Congenital Absence of Lacrimal Puncta and Salivary Glands

Congenital absence of lacrimal puncta and salivary glands means that a baby is born without the tiny tear drainage openings on the eyelids (lacrimal puncta) and without some or all of the main saliva-making glands. Because of this, the eyes do not drain or lubricate normally, and the mouth is very dry. This problem is rare and is often part of a genetic syndrome called “aplasia of lacrimal and salivary glands (ALSG)” or “LADD syndrome.”

Congenital absence of lacrimal puncta and salivary glands is a rare birth defect where a baby is born without the tiny drainage holes of the tear system (lacrimal puncta) and without some or all of the tear or saliva-producing glands. This condition is usually part of a wider disorder called aplasia of the lacrimal and salivary glands (ALSG). People have very dry eyes and very dry mouth from early life, which can cause eye damage, dental decay, mouth infections, and problems eating or speaking.

Because the glands and puncta never formed properly, treatment cannot “grow them back.” Instead, care focuses on protecting the eye surface with moisture, keeping the mouth wet, preventing tooth decay, and treating complications early. Management often needs a team: ophthalmologist, dentist, oral medicine specialist, sometimes geneticist and psychologist, because this is a lifelong condition that can strongly affect quality of life.

People with this condition usually have eye irritation, repeated eye infections, and trouble with eating and teeth because saliva is missing. The disorder is usually present from birth and may run in families in an autosomal dominant way (one changed copy of the gene from a parent is enough to cause disease).

Other Names

This condition has several other names in medical articles. These different names all describe very similar problems of missing tear and saliva glands.

• Aplasia of lacrimal and salivary glands (ALSG) – this is the most common name and stresses that both tear and saliva glands are absent or under-developed.

• Congenital absence of salivary glands and lacrimal puncta – this name clearly says the child is born without these structures.

• Alacrima-aptyalism syndrome – “alacrima” means no tears and “aptyalism” means no saliva.

• Lacrimal–salivary gland aplasia – used when imaging shows that the glands themselves are missing or tiny.

• Lacrimo-auriculo-dento-digital (LADD)–related lacrimal–salivary aplasia – used when the same child also has ear, teeth, or finger problems as seen in LADD syndrome.

Types

Doctors may group this condition into simple “types” based on how many glands are missing and whether other body parts are involved. These types are not strict rules but help describe the pattern in each patient.

1. Isolated ALSG (only eyes and mouth) – only the lacrimal and salivary systems are abnormal, without clear problems in ears, teeth, or limbs.

2. LADD-associated type – absence or under-development of lacrimal puncta and salivary glands together with ear shape changes, hearing problems, tooth defects, or finger and toe malformations.

3. Ectodermal-dysplasia–associated type – lacrimal and salivary aplasia occurring in children with broader ectodermal problems (hair, teeth, skin, glands) such as hereditary ectodermal dysplasia.

4. Other craniofacial-syndrome–associated type – salivary gland aplasia together with syndromes like Down syndrome or other craniofacial syndromes where facial development is disturbed.

5. Partial vs complete aplasia – in some children, only some glands or only some puncta are missing (partial), while in others all major salivary glands and all four puncta are absent (complete).

6. Unilateral vs bilateral – sometimes only one side of the face is affected (unilateral), but often both sides show missing glands or puncta (bilateral).

Causes

Here “cause” means the underlying reason why the baby’s glands did not form normally during early pregnancy. In many patients, the cause is a change (mutation) in genes that control growth signals in the face.

1. FGF10 gene mutation – Many families with ALSG have a harmful change in the FGF10 gene. This gene makes a growth factor that guides the formation of lacrimal and salivary glands. When it is faulty, these glands may be absent or very small.

2. FGFR2 gene mutation – In some LADD syndrome patients, a mutation in the FGFR2 gene (a receptor for FGF10) leads to poor signaling and defective development of glands, ears, teeth, and bones.

3. FGFR3 gene mutation – Other LADD patients carry changes in FGFR3, another receptor for fibroblast growth factors, again disturbing normal facial and gland growth.

4. Autosomal dominant inheritance – ALSG and LADD often pass from an affected parent to a child in an autosomal dominant pattern, so a single altered copy of the gene is enough to cause the condition.

5. De novo (new) mutation in the child – Sometimes neither parent is affected, and the gene change arises for the first time in the child’s early development. This is called a de novo mutation.

6. LADD syndrome as the primary diagnosis – In some children the broader LADD syndrome, not isolated ALSG, is the main diagnosis, and the gland absence is one part of that syndrome.

7. General ectodermal development defect – Many cases of salivary gland aplasia occur along with disorders of ectoderm (skin, hair, glands), suggesting a wider disturbance in early ectoderm formation rather than a problem limited to one organ.

8. Association with hereditary ectodermal dysplasia – Published reports describe salivary gland aplasia in patients with ectodermal dysplasia, supporting the idea that shared pathways control hair, teeth, and gland development.

9. Association with mandibulofacial dysostosis or hemifacial microsomia – Some children with these craniofacial syndromes also show missing salivary glands, probably because facial bone and gland primordia share the same early growth fields.

10. Association with Down syndrome and other chromosomal conditions – Case reports show salivary gland aplasia or hypoplasia in some patients with Down syndrome, linking major chromosomal changes with disturbed gland development.

11. Primary lacrimal system agenesis – For some patients, the primary problem is agenesis (non-formation) of the lacrimal drainage system, including the puncta, which may occur alone or together with salivary aplasia.

12. Early embryonic disturbance of nasolacrimal duct formation – The lacrimal outflow tract forms during specific weeks of pregnancy, and an error in this process can leave the puncta absent.

13. Early embryonic disturbance of salivary gland buds – Major salivary glands arise from epithelial buds in the sixth to eighth week of gestation; disruption at this time can result in aplasia.

14. Other FGF-pathway gene changes not yet fully defined – Because ALSG/LADD involve FGF10 and its receptors, it is likely that rare changes in other pathway genes could also disturb gland formation, even if they have not all been clearly mapped yet.

15. Unknown genetic variants (idiopathic cases) – In some families the pattern is strongly genetic, but no exact mutation has yet been found using current tests, so the cause is listed as unknown.

16. Variable expressivity of the same mutation – The same FGF10 or FGFR mutation can cause severe aplasia in one person and only mild hypoplasia in another, showing that modifier genes and environment also play a role.

17. Reduced blood supply to developing facial buds (theoretical) – Some authors suggest that disturbed local blood flow during facial development may worsen the effect of genetic changes, although direct proof for this in ALSG is limited.

18. Interaction with other craniosynostosis genes (theoretical) – FGFR2 and FGFR3 are also involved in craniosynostosis syndromes like Crouzon and Pfeiffer syndromes, so overlapping pathways might contribute to rare complex cases with gland aplasia.

19. Multifactorial background (genes plus unknown factors) – Many rare congenital anomalies have both inherited and unknown influences, so ALSG/LADD may reflect a mix of gene changes and subtle environmental factors that we do not yet fully understand.

20. Truly sporadic isolated agenesis – Rare patients show absence of puncta and salivary glands with no family history and no other syndrome recognized; in these cases, the cause remains unexplained even after full work-up.

Symptoms

Symptoms mainly come from dry eyes and dry mouth, plus problems caused by long-term lack of tears and saliva.

1. Very dry eyes (alacrima) – The child or parents notice that tears are absent or very reduced, even when the child cries or when the eyes are irritated.

2. Burning or gritty eye feeling – Because the eye surface is not well lubricated, it can feel sore, gritty, or as if sand is in the eye.

3. Red eyes and recurrent conjunctivitis – The thin membrane over the white of the eye can become red and inflamed again and again because tears do not wash away germs and debris.

4. Overflow tearing or epiphora in some patients – If other tear structures are abnormal, the child may paradoxically show constant wetness at the eyelids because tears cannot drain through missing puncta.

5. Sensitivity to wind or smoke – Even mild irritants can cause strong discomfort because the ocular surface lacks a stable tear film to protect it.

6. Dry mouth (xerostomia) – The child or older patient feels the mouth is constantly dry, has trouble swallowing dry foods, and may need water very often.

7. Difficulty chewing and swallowing – Saliva helps soften food and start digestion; without it, chewing is tiring and swallowing can be uncomfortable or slow.

8. Speech problems from dryness – A very dry mouth can make speaking for a long time hard, with frequent pauses to sip water.

9. Rapid tooth decay (dental caries) – Saliva normally washes away food and neutralizes acids; without it, cavities form quickly, even with good brushing.

10. Gum and soft-tissue infections – The tongue, cheeks, and gums may become sore, red, or infected, including yeast infections like oral candidiasis.

11. Bad breath (halitosis) – Lack of saliva allows bacteria and food debris to stay in the mouth, which can cause chronic bad breath.

12. Difficulty wearing dentures later in life – Dry mouth makes it hard for dentures to stick and can cause sore spots and ulcers.

13. Taste changes (dysgeusia) – Saliva is important to dissolve food chemicals for taste, so some patients notice reduced or altered taste.

14. Features of associated syndromes – When LADD or other syndromes are present, there may be cup-shaped ears, missing teeth, enamel defects, limb anomalies, or hearing loss in addition to dryness.

15. Family history of similar dryness and dental problems – Several relatives across generations may have dry eyes and dry mouth, suggesting the same inherited condition.

Diagnostic Tests

Doctors use many tests to confirm the condition, to measure how dry the eyes and mouth are, and to rule out other diseases like autoimmune Sjögren syndrome. Below, tests are grouped by type.

Physical Examination Tests

1. Eye examination with slit-lamp – An eye doctor looks closely at the eyelids, lashes, conjunctiva, and cornea using a special microscope. They can see that the lacrimal puncta openings are missing and that the eye surface looks dry or damaged.

2. Eyelid margin inspection for punctal agenesis – The doctor carefully everts (flips) the eyelids and looks at the usual puncta sites; if no opening is seen in any lid, punctal agenesis is diagnosed.

3. Oral and dental examination – The dentist or doctor checks for dry mucosa, stringy or absent saliva, sticky tongue, rampant caries, and gum disease; these physical signs suggest absent or severely reduced salivary gland function.

4. Systemic examination for syndromic features – Ears, teeth, hands, and other organs are examined to look for signs of LADD or ectodermal dysplasia, such as cup-shaped ears, missing teeth, and limb defects.

Manual Clinical Tests (Bedside / Chairside)

5. Schirmer tear test – Small paper strips are placed in the lower eyelids for five minutes to measure how many millimeters of the strip are wetted by tears; very low values show severe tear deficiency.

6. Fluorescein tear break-up time (TBUT) – Fluorescein dye is put into the eye, and the time until the smooth tear film breaks into dry spots is measured under blue light; short TBUT suggests an unstable, dry tear film.

7. Basic salivary flow exam at the chair – The examiner asks the patient to rest with the mouth slightly open and observes whether saliva pools under the tongue or at gland openings; lack of visible saliva suggests very low flow.

8. Stimulated whole salivary flow (simple sialometry) – The patient chews paraffin or gum and spits into a container for a fixed time; the volume or weight is measured to estimate stimulated flow rate, which is very low in salivary aplasia.

Laboratory and Pathological Tests

9. Quantitative sialometry in the lab – More formal sialometry uses standardized collection and weighing or measuring of saliva to give exact flow rates for unstimulated and stimulated saliva, helping to document severe hyposalivation.

10. Saliva composition analysis – In some centers, saliva pH, electrolytes, and protein content are measured; in gland aplasia, flow is very low, and composition may be altered, supporting the diagnosis.

11. Blood tests to exclude autoimmune Sjögren syndrome – Antibodies such as anti-SSA/Ro and anti-SSB/La, along with inflammatory markers, are checked; in pure ALSG, these tests are usually negative, which helps separate it from autoimmune dry eye and dry mouth.

12. Minor labial salivary gland biopsy – A tiny piece of lip mucosa is removed and examined under the microscope; in ALSG, there may be fewer or abnormal minor glands, but classic Sjögren-type lymphocytic destruction is often absent.

13. Histology of any present gland tissue – When any salivary tissue is found on biopsy or surgery, the pathologist can show reduced or abnormal gland lobules compared with normal controls, confirming developmental aplasia or hypoplasia.

14. Genetic testing panel for ALSG / LADD genes – DNA tests check for pathogenic variants in FGF10, FGFR2, FGFR3 and related genes; a positive result strongly supports ALSG/LADD as the cause of the congenital gland absence.

Electrodiagnostic Tests

15. Electrogustometry (EGM) for taste function – A small device delivers tiny electrical currents to the tongue to measure taste thresholds; in severe dryness, taste thresholds may be altered, helping to assess functional impact of salivary loss.

16. Bedside taste tests with chemical solutions – Simple taste strips or drops containing sweet, salty, sour, and bitter solutions are used to check if the patient can identify tastes; changes may reflect the effect of dry mouth on taste.

17. Optional nerve-function studies in complex cases – In rare, complex patients, doctors may use nerve tests to make sure facial and glossopharyngeal nerves are working, to separate gland aplasia from nerve-related taste or dryness problems.

Imaging Tests

18. Ultrasound of major salivary glands – High-frequency sound waves create images of the parotid and submandibular glands; in salivary aplasia, glands may be absent or very small, and normal gland tissue is not seen.

19. MRI or CT of salivary and lacrimal glands – Cross-sectional imaging of the head and neck can show complete absence or hypoplasia of glands and may also reveal associated craniofacial abnormalities.

20. Sialography or salivary gland scintigraphy – In older children or adults, contrast studies of the ducts or nuclear medicine scans using technetium assess how much salivary tissue is present and how well it works; in aplasia, uptake and excretion are very low or absent.

Non-pharmacological treatments (Therapies and other measures)

1. Preservative-free artificial tears and gels
Frequent use of preservative-free artificial tear drops and thicker eye gels is the basic therapy. These drops replace missing tears, wash away dust, and make blinking smoother, so the cornea does not scratch with every blink. Preservative-free products are safer for long-term, frequent use, especially when the eye surface is already fragile and inflamed.

2. Lubricating eye ointment at night
At night, many people sleep with slightly open lids, so their already dry eyes become extremely dry. A thick lubricating eye ointment before bed forms a protective layer across the cornea. This slows water loss while you sleep and lowers the risk of painful corneal erosions, scarring, and even perforation in severe cases of gland agenesis.

3. Moisture chamber goggles
Moisture chamber goggles or wrap-around “swim-goggle style” glasses trap a humid air pocket around the eyes. This reduces evaporation of the tear film and protects against wind and fans. For people with no tear glands, this simple mechanical method can greatly improve comfort and help prevent chronic damage to the cornea over time.

4. Protective wrap-around sunglasses
Large, close-fitting sunglasses block wind, dust, and bright light. By reducing evaporation and irritation, they help the limited artificial tear layer stay on the eye longer. They also protect light-sensitive, inflamed eyes and help reduce reflex blinking and rubbing, which may otherwise worsen surface damage.

5. Room humidifier and avoiding dry air
Using a cool-mist humidifier at home and avoiding strong air conditioning, car vents, or heaters blowing directly on the face can reduce eye and mouth dryness. Higher humidity means less evaporation from exposed surfaces like the cornea and the oral mucosa. This is a simple environmental change that supports all other treatments.

6. Regular blinking and screen-break habits
Long screen time makes everyone blink less. For someone without normal tears, this is especially harmful. Training yourself to blink fully and to follow the “20-20-20 rule” (every 20 minutes, look 20 feet away for 20 seconds) helps spread lubricants evenly and reduces strain, redness, and burning.

7. Warm compresses and eyelid hygiene
Warm compresses on the eyelids help melt thick oils in the meibomian glands (oil glands in the lids). Gentle lid cleaning keeps lid margins free of crusts. Even when lacrimal glands are absent, healthy lid oils slow evaporation of artificial tears and reduce irritation and secondary blepharitis (lid inflammation).

8. Frequent small sips of water
Because salivary glands are absent or very small, the mouth dries quickly. Sipping water regularly, instead of gulping large amounts occasionally, keeps the lining of the mouth moist. This improves speaking, swallowing, and comfort, and helps reduce friction injuries to the tongue and cheeks.

9. Sugar-free chewing gum
Chewing sugar-free gum stimulates any remaining minor salivary tissue and also increases blood flow to the oral mucosa. Even when major glands are missing, the mechanical movement and saliva from tiny glands in the lips and palate may increase slightly, making the mouth less sticky. Sugar-free gum also lowers caries risk compared with sugary gums.

10. Sugar-free lozenges or xylitol mints
Sugar-free lozenges and xylitol mints dissolve slowly, encouraging more frequent swallowing and slight saliva flow from whatever tissue remains. Xylitol can also reduce growth of cavity-causing bacteria, which is especially useful when saliva, the natural cleansing fluid, is nearly absent.

11. Saliva substitutes and oral moisturizing gels
Commercial saliva substitutes come as sprays, gels, or rinses that coat the mouth with a slippery film. Many contain carboxymethylcellulose or supersaturated calcium-phosphate blends and are specifically approved for xerostomia (dry mouth) from different causes. They help moistening, improve comfort, and support chewing and speaking.

12. High-fluoride toothpaste and mouth rinses
Without saliva, teeth are at high risk for rapid decay, because natural washing and mineral replacement are missing. High-fluoride toothpaste and prescription rinses strengthen enamel and make it more resistant to acids from foods and bacteria. This is a central non-drug strategy to prevent early tooth loss in salivary gland aplasia.

13. Custom fluoride trays from the dentist
Dentists can make custom trays that hold fluoride gel closely against all teeth for several minutes each day. This gives extra strong, targeted enamel protection in people with severe dry mouth. It is often recommended in case reports of major salivary gland aplasia to prevent rampant caries and tooth fractures.

14. Regular dental check-ups and early restorative care
Because decay develops quickly, dental visits are needed more often than usual, sometimes every 3–4 months. Early filling of small cavities, use of sealants, and careful plaque control help avoid root canal treatments and extractions. Timely dental care is a core part of management for congenital absence of salivary glands.

15. Speech and swallowing therapy
Dry eyes and mouth can change blinking patterns, facial expressions, articulation, and swallowing. A speech-language therapist can teach safer swallowing techniques, pacing of bites and sips, and strategies to speak clearly without over-straining the voice or lips when the mouth feels very dry.

16. Avoiding tobacco, alcohol mouthwashes, and irritants
Smoking, alcohol-based mouthwashes, and spicy or very acidic foods strip away moisture and damage fragile oral tissues. In someone with almost no natural saliva, these irritants can cause ulcers and infections. Avoiding them protects the mucosa and reduces burning mouth sensations.

17. Lip balms and barrier creams
The lips often crack and peel because of constant dryness and mouth breathing. Regular use of bland lip balms or petrolatum-based ointments creates a barrier that keeps water in the skin and shields lips from wind and sun, lowering the risk of painful fissures and secondary infections.

18. Diet modification to softer, moist foods
Choosing softer, saucier foods and adding gravies, soups, or yogurt makes chewing and swallowing easier in a dry mouth. Hard, dry foods like crackers can scrape the mucosa and are hard to swallow. Planning meals this way can reduce weight loss, fatigue, and fear of eating in public.

19. Environmental adjustments (avoiding hot, dry climates when possible)
If possible, living or spending more time in less dry environments helps both eyes and mouth. Avoiding long stays in hot, windy outdoor settings and minimizing time in low-humidity, air-conditioned places can significantly reduce symptoms and the need for extra drops and sprays.

20. Psychological support and patient education
This condition is lifelong and can be isolating, especially when it starts in childhood. Clear education about the disease, realistic expectations, and access to counseling or support groups help patients cope and stay motivated with complex daily care routines for eyes, teeth, and mouth.

Drug treatments

Important safety note: Exact doses, timing, and combinations must always be set by a qualified doctor. I will describe general principles only. Never start or change any medicine without your own doctor’s advice, especially in rare congenital diseases and in children or teenagers.

1. Cyclosporine ophthalmic emulsion 0.05% (Restasis)
Restasis is a prescription eye drop approved to increase tear production in people whose tears are reduced because of inflammation in chronic dry eye disease. It is an immunomodulator: it calms down T-cell–driven inflammation in the lacrimal tissue and ocular surface, allowing remaining tear-secreting cells to work better. It is usually used twice daily long term and can cause burning, redness, or blurred vision in some patients.

2. Cyclosporine ophthalmic solution 0.09% (Cequa / OTX-101)
A stronger cyclosporine solution has been approved to increase tear production in keratoconjunctivitis sicca. It uses a nanomicellar formulation to improve penetration into the eye surface. Its purpose and basic mechanism are similar to Restasis: reduce inflammatory damage and help the eye produce more natural tears over time, with side effects mainly local irritation and redness.

3. Lifitegrast 5% ophthalmic solution (Xiidra)
Xiidra is an eye drop approved to treat the signs and symptoms of dry eye disease. It blocks the interaction between LFA-1 and ICAM-1, which are molecules involved in inflammatory cell adhesion on the eye surface. This reduces inflammation and can improve both symptoms and corneal staining. It is usually used twice daily and can cause temporary blurred vision, irritation, or an unusual taste.

4. Varenicline nasal spray (Tyrvaya)
Tyrvaya is a nasal spray, not an eye drop, but it is approved for dry eye disease. It stimulates receptors on trigeminal parasympathetic pathways inside the nose, which then signal the lacrimal functional unit to make more tears. It is usually sprayed in each nostril several times per day. Common side effects include sneezing, cough, and throat irritation.

5. Short-course topical corticosteroid eye drops
Very low-dose steroid eye drops (such as loteprednol) may be used briefly when the eye surface is severely inflamed. Their purpose is to quickly reduce redness, pain, and immune activation so that other long-term therapies, like cyclosporine, can work better. Because of risks of glaucoma and cataract with long use, these medicines must be carefully supervised and are usually limited to short periods.

6. Autologous serum eye drops
These are drops made from the patient’s own blood serum, prepared in a specialized center. Serum contains growth factors, vitamins, and proteins similar to natural tears. When applied to the eye, they help heal the cornea, support nerve health, and improve symptoms in severe dryness when no or very little tear is produced. Side effects mainly relate to contamination risk, so strict sterile preparation is essential.

7. Platelet-rich plasma (PRP) eye drops
PRP eye drops are another regenerative preparation made from the patient’s own blood. The high platelet content provides many growth factors that help repair damaged corneal epithelium and nerves. They are used in very severe dry eye and ocular surface disease, often when standard drops have failed. Treatment requires repeated blood draws and careful handling in a specialized clinic.

8. Cenegermin (Oxervate) ophthalmic solution
Cenegermin is recombinant human nerve growth factor (NGF) approved for neurotrophic keratitis, a disease where corneal nerves are damaged and the surface fails to heal. It promotes nerve regeneration and corneal healing. While not approved specifically for congenital gland absence, it may be considered in selected cases with severe corneal breakdown under specialist supervision. It is given as frequent eye drops for several weeks and can cause eye pain or inflammation.

9. Pilocarpine tablets (Salagen)
Pilocarpine is an oral muscarinic agonist approved to treat xerostomia (dry mouth) caused by salivary gland hypofunction, such as after head-and-neck radiotherapy or in Sjögren’s syndrome. It stimulates remaining exocrine gland tissue to secrete more saliva and sometimes tears. Typical side effects include sweating, flushing, increased urination, and gastrointestinal upset, so dosing and suitability must be checked by a doctor.

10. Cevimeline capsules (Evoxac)
Cevimeline is another oral muscarinic agonist approved for treatment of dry mouth in patients with Sjögren’s syndrome. It binds mainly M1 receptors and increases salivary and sweat gland secretion. It can improve global dry-mouth symptoms and measured salivary flow. Side effects include sweating, nausea, runny nose, diarrhea, and possible heart rhythm and lung effects, so it must be prescribed with caution and regular review.

11. Supersaturated calcium-phosphate rinse (NeutraSal)
NeutraSal is a powder that forms a supersaturated calcium and phosphate oral rinse when dissolved in water. It is indicated for dryness of the mouth and oral mucosa from various causes. The solution helps restore ionic balance, maintain moisture, and relieve painful fissures. It is often used several times daily as part of an oral hygiene program in severe xerostomia.

12. Caphosol artificial saliva
Caphosol is an electrolyte solution containing calcium and phosphate ions, approved for dryness of the mouth or throat (xerostomia) from many causes, including salivary gland dysfunction. It is swished and spit or swallowed several times a day. By supplying minerals and moisture, it reduces pain, improves speaking and eating, and supports oral hygiene in patients with very low saliva.

13. Supersaturated calcium-phosphate rinse (SalivaMAX or similar)
Some products similar to NeutraSal provide supersaturated calcium-phosphate solutions for dry mouth. They are used as part of daily oral care to relieve burning, help chewing, and reduce mucosal injury. Although they do not restore gland tissue, they mimic some protective functions of normal saliva. Side effects are usually mild, such as temporary taste changes.

14. Topical antifungal agents for oral candidiasis
Very dry mouths are prone to fungal infections like oral thrush. When white patches, soreness, or burning occur, doctors may prescribe antifungal lozenges or rinses (for example, nystatin or similar agents). Their purpose is to clear infection so that mucosa can heal. They are not specific to congenital gland absence but are often needed repeatedly in such patients.

15. Antibacterial mouth rinses (e.g., chlorhexidine)
In high-caries-risk patients with xerostomia, short-term chlorhexidine mouthwash may be prescribed to reduce harmful bacteria. It supports fluoride therapies and careful brushing to prevent caries and gum disease. Because long use may stain teeth and disturb normal flora, dentists usually limit the duration and monitor closely.

(In real practice there are fewer than 20 distinct, strongly evidence-based drugs specifically for this rare condition; care relies mainly on these key medicines plus the non-drug measures you saw above.)

Dietary molecular supplements

Always check supplements with your doctor or pharmacist, especially if you take other medicines or have chronic illnesses.

1. Omega-3 fatty acids (fish oil or algae oil)
Omega-3 supplements may help reduce inflammation in the eye surface and meibomian glands, supporting a more stable tear film. They can also benefit cardiovascular health. Mechanistically, they are converted into anti-inflammatory lipid mediators that may soften lid oils and reduce ocular surface irritation.

2. Vitamin A
Vitamin A is essential for healthy corneal and conjunctival epithelium. Deficiency can worsen dryness and keratinization. Supplementation (within safe limits) supports epithelial repair and mucin production. Too much vitamin A is toxic, so doses must be supervised.

3. Vitamin D
Vitamin D modulates immune responses and supports bone and dental health. In people with chronic inflammatory dry eye and dry mouth, correcting deficiency may help overall immunity and reduce risk of dental problems, although it is not a specific cure.

4. Vitamin C
Vitamin C is a water-soluble antioxidant important for collagen formation and wound healing. Adequate intake helps the eye surface and oral mucosa repair micro-injuries from friction and dryness, and supports gum health around vulnerable teeth.

5. Vitamin E
Vitamin E is a fat-soluble antioxidant that protects cell membranes from oxidative stress. In combination with other antioxidants, it may help protect the ocular surface and oral tissues from chronic irritation caused by severe dryness.

6. Zinc
Zinc is involved in many enzymes important for healing and immune function. Mild deficiency can slow wound repair and worsen mucosal problems. Controlled zinc supplementation, if deficiency is confirmed, may help improve healing of recurrent mouth ulcers or corneal surface injuries.

7. Selenium
Selenium is part of antioxidant enzymes such as glutathione peroxidase. Adequate selenium may support general immune balance and protect tissues from oxidative damage. Because the safe dose range is narrow, it should only be used after medical advice.

8. Probiotics
Certain oral or gut probiotic products may help balance bacteria in the mouth and gut. In very dry mouths, harmful bacteria flourish easily. While evidence is still developing, probiotics may support oral hygiene and reduce infections when combined with brushing, fluoride, and saliva substitutes.

9. L-glutamine
Glutamine is a fuel for rapidly dividing cells in the gut and mucosa. Some clinicians use it in patients with mucositis or chronic mucosal damage. It may support repair of fragile oral lining, though evidence in congenital salivary aplasia is limited.

10. Multivitamin tailored by a doctor or dietitian
Because eating can be difficult and repeated dental work may limit food choices, a personalized multivitamin and mineral supplement can help cover gaps in the diet. This does not treat the disease itself but supports overall strength, immunity, and healing capacity.

Immunity-supportive and regenerative / stem-cell related therapies

1. Autologous serum eye drops (as a regenerative therapy)
As described earlier, serum eye drops bring natural growth factors and vitamins directly to the cornea. These molecules support epithelial regeneration and nerve health, acting as a biological “tear substitute” that is closer to real tears than artificial lubricants. They are considered a form of regenerative therapy for the ocular surface.

2. Platelet-rich plasma (PRP) eye drops
PRP is rich in platelet-derived growth factors and cytokines that stimulate healing and tissue repair. When used as eye drops, it may improve chronic epithelial defects and reduce pain in severe dry eye syndromes. It is experimental in many places and should be used only in specialized centers.

3. Umbilical cord serum eye drops (where available)
In some research settings, serum from screened umbilical cord blood is processed into eye drops. It contains high levels of trophic factors and may support corneal and conjunctival regeneration in severe ocular surface disease. This is not standard therapy everywhere and is usually part of clinical protocols.

4. Cenegermin (Oxervate) for corneal nerve regeneration
Cenegermin is an example of a biologic drug that directly targets corneal nerves. In neurotrophic keratitis it stimulates nerve growth and restores corneal sensitivity. In theory, similar nerve-supportive strategies may help protect the cornea in extreme dryness where repeated damage threatens nerve health, but any off-label use must be specialist-led.

5. Amniotic membrane grafts (biologic surgical dressing)
Although done in the operating room, amniotic membrane is a biologic “bandage” placed on the eye surface. It contains growth factors and anti-inflammatory proteins. It helps epithelial healing and reduces scarring after severe corneal damage in very dry eyes. It is often combined with intensive drops and protective measures.

6. Future stem-cell–based ocular surface reconstruction
Research is ongoing on limbal stem cell transplantation and other stem-cell–based methods to rebuild damaged ocular surface tissue. At present these are used only in very specific conditions and in specialized centers, not as routine care for gland aplasia. Still, they represent possible future options when standard therapies cannot preserve vision.

Surgeries (Procedures and why they are done)

1. Procedures for punctal or lacrimal outflow abnormalities
In some patients, structures are malformed rather than totally absent. Eye surgeons may perform punctoplasty, canalicular reconstruction, or dacryocystorhinostomy to improve drainage and reduce infections if abnormal ducts trap tears and mucus. In pure gland absence, surgery focuses more on protecting the surface than reconstructing glands.

2. Tarsorrhaphy (partial eyelid closure)
In very severe eye dryness with recurrent corneal ulcers, surgeons may partially sew the eyelids together at the sides to reduce the opening. This decreases evaporation and mechanical stress on the cornea, giving it a chance to heal. It is usually considered when other treatments fail to prevent damage.

3. Amniotic membrane transplantation
When the cornea has persistent defects or scarring, surgeons may place an amniotic membrane graft over it. This membrane acts as a biological dressing and slowly dissolves as the surface heals underneath. It lowers inflammation and scarring risk in severe dry eye–related damage.

4. Salivary or minor gland transplantation for ocular lubrication
In some centers, functioning salivary gland tissue (for example from the submandibular gland) can be transplanted to the temple area so that saliva-like fluid can be directed toward the eye surface to act as a natural tear substitute. This is complex surgery and only suitable when some gland tissue is available and the patient is carefully selected.

5. Dental restorative and rehabilitative procedures
Because teeth are so vulnerable in salivary gland aplasia, extensive dental work is common: fillings, crowns, root canals, extractions, and sometimes dentures or implants. These procedures aim to restore chewing, aesthetics, and speech, and to remove painful, infected teeth that cannot be saved. Prevention is still better than repeated major dental surgeries.

Prevention

1. Maintain strict daily eye lubrication with drops, gels, and ointment as prescribed.

2. Use moisture-protecting eyewear and avoid windy, very dry environments.

3. Follow a daily oral-care routine with high-fluoride toothpaste, flossing, and saliva substitutes.

4. Visit the dentist more often than usual (for example every 3–4 months) for early detection of caries.

5. Avoid tobacco, alcohol mouthwashes, and very spicy or acidic foods that irritate dry tissues.

6. Keep good hydration by drinking water regularly throughout the day.

7. Treat any eye redness, pain, or mouth sores early instead of waiting they “go away.”

8. Keep all follow-up appointments with ophthalmology, dentistry, and oral medicine specialists.

9. Use protective strategies (humidifier, screen breaks, protective glasses) every day, not only when symptoms are bad.

10. Ask about vaccination and general health checks to reduce systemic infections that might worsen eye and mouth problems.

When to see a doctor

You should see an eye doctor (ophthalmologist) or go to emergency care urgently if you have sudden severe eye pain, sharp drop in vision, strong light sensitivity, or the feeling that something is stuck in the eye that does not improve with lubrication. These may be signs of corneal ulcer, infection, or even perforation, which need immediate treatment.

You should see your dentist or oral specialist promptly if you notice mouth ulcers, white patches, burning pain, difficulty swallowing, new bad breath, or bleeding gums. Early treatment can prevent deep infections, abscesses, and tooth loss. Regular planned check-ups are just as important as emergency visits.

If you feel very low, anxious, or overwhelmed by the constant care this condition needs, it is also important to talk to your doctor, a psychologist, or a counselor. Emotional support is a real and important part of treatment.

What to eat and what to avoid

Helpful to eat / drink

1. Soft, moist foods such as soups, stews, yogurt, and smoothies that are easier to chew and swallow.

2. Foods with healthy fats (olive oil, avocado, nut butters) that add slipperiness and calories without needing much chewing.

3. Sugar-free gum or xylitol mints after meals to help mechanical cleansing and slight saliva stimulation.

4. Plenty of plain water throughout the day, taken in small, frequent sips.

5. Foods rich in vitamins and minerals (fruits, vegetables, lean proteins) to support healing and general health, adjusting texture to what you can manage.

Better to avoid or limit

1. Sugary drinks and sweets, which greatly speed up tooth decay when saliva is missing.
2. Very dry, crumbly foods (crackers, dry toast, chips) that are hard to swallow and may injure mouth tissues.
3. Highly acidic foods and drinks (cola, citrus juices) that can erode enamel and sting the mouth
4. Alcoholic drinks and alcohol-based mouthwashes, which dry and irritate the mucosa even more.
5. Very spicy or salty foods that cause burning and discomfort on already fragile, dry tissues.

Frequently asked questions (FAQs)

1. Is congenital absence of lacrimal puncta and salivary glands curable?
No. The missing glands and structures cannot be regrown with current medicine. Treatment focuses on protecting eyes and mouth, reducing symptoms, and preventing complications like blindness and tooth loss. Research into regenerative and stem-cell therapies is ongoing, but at present care is supportive rather than curative.

2. Is this condition genetic?
In many people, absence of lacrimal and salivary glands is part of ALSG, which is often inherited in an autosomal dominant pattern with variable expression. That means a parent may be mildly affected while a child is more severely affected. Genetic counseling can help families understand risks and testing options.

3. Can children with this condition live a normal life?
Yes, many can attend school, work, and have active lives, but they need strict lifelong eye and oral care. Early diagnosis, regular specialist follow-up, and good daily habits (drops, saliva substitutes, dental care) make a big difference in long-term vision, teeth, and quality of life.

4. Are dry-eye drugs like cyclosporine or lifitegrast safe to use long term?
Clinical studies and FDA reviews show that these medicines can be used long term in chronic dry eye disease, with mainly local side effects such as burning or irritation. However, each patient’s risk–benefit balance is different, especially in rare congenital disorders, so they must be used under regular ophthalmology supervision.

5. Will saliva-stimulating tablets work if my major salivary glands are completely absent?
Medicines like pilocarpine and cevimeline work by stimulating remaining gland tissue. If there is truly no functional gland tissue, their effect may be small or absent, and side effects may outweigh benefits. Imaging and specialist assessment are needed to see whether trying these medicines makes sense in your case.

6. Why is dental care so important in this condition?
Saliva protects teeth by washing away food, neutralizing acids, and bringing minerals back into enamel. Without it, cavities and gum disease appear very quickly, sometimes in young children. High-fluoride care, saliva substitutes, and frequent dentist visits are crucial to keep teeth for as long as possible.

7. Can contact lenses be used?
In most patients with severe dry eye from gland absence, regular contact lenses are risky because they increase dryness and can damage the cornea. In very selected cases, special scleral lenses that hold a fluid reservoir may be used under expert supervision, but this is highly individualized.

8. Will drinking more water alone fix my dry mouth?
No. Water helps a lot and should be used frequently, but it does not replace the complex functions of saliva. You still need saliva substitutes, fluoride, and dental care to protect teeth and oral tissues.

9. Are there special toothpastes for people with no saliva?
Yes. High-fluoride pastes and products labeled for “dry mouth” are often recommended. They may contain extra lubricants and ingredients that reduce irritation. Your dentist can choose the right product based on your age, decay risk, and other health issues.

10. Can eye and mouth dryness get worse over time?
Yes. Even though the basic defect is present from birth, repeated damage, scarring, infections, and aging can make symptoms worse. That is why consistent daily care and regular checks are important, even when you feel “okay” for a while.

11. Are stem-cell or gene therapies available now?
At the moment, stem-cell–based and gene-based treatments for this specific condition are experimental and limited to research or very specialized centers, often for other eye diseases. They are not routine yet, but they are areas of active research for future treatment.

12. How often should I see an ophthalmologist?
The exact schedule depends on severity, but many experts recommend at least yearly visits for stable patients, and more often (every few months) when there is active corneal disease, new symptoms, or treatment changes. Children often need closer monitoring as their eyes grow.

13. How often should I see a dentist?
People with severe xerostomia are usually advised to see a dentist every 3–4 months, not just once a year. This allows early detection of new caries, adjustment of fluoride treatments, and reinforcement of home-care instructions.

14. Is it safe to use over-the-counter eye drops as often as I want?
Preservative-free artificial tears can be used very frequently, often many times per day. However, drops with preservatives can damage the eye surface when used too often. Your ophthalmologist can help you choose safe products and frequency based on your situation.

15. What should I tell new doctors or dentists about my condition?
Always explain that you were born without lacrimal puncta and salivary glands and that you have severe dry eye and dry mouth. Bring a list of your medicines and treatments. This helps new providers avoid prescribing drugs that worsen dryness and encourages them to plan extra protection for your eyes and teeth.
