Stomatopyrosis

Stomatopyrosis means a constant or frequent burning, scalding, or tingling feeling in your mouth even though the lining of the mouth looks normal. The burning is usually felt on the tongue but can affect the lips, palate, or the whole mouth. Doctors often call this condition burning mouth syndrome (BMS). By definition, symptoms are present most days for months, and the mouth exam is normal, with no sores or visible disease causing the pain. NCBI+2PMC+2

Pain from stomatopyrosis is real and distressing. In many people, there is no single clear cause that explains the burning. When no cause is found, it is called primary (idiopathic) BMS. When a cause is found—like a medicine side effect, nutritional deficiency, dry mouth, infection, reflux, or an allergy—it is called secondary BMS. Treating the underlying cause can help when it is secondary BMS. Cleveland Clinic

Stomatopyrosis—now usually called burning mouth syndrome (BMS)—means a persistent burning, scalding, or tingling feeling in the mouth (often the tongue) with normal-looking oral tissues and no obvious cause. By modern criteria, the burning occurs most days for >2 hours/day for >3 months. Many patients also notice dry mouth and altered taste. BMS is thought to be a chronic neuropathic orofacial pain disorder. Before diagnosing BMS, clinicians rule out other conditions (e.g., thrush, nutritional deficiency, medication side-effects, Sjögren’s, diabetes, allergy, oral lichen planus). PMC+3NIDCR+3ICHD-3+3

BMS is more common in women (especially after menopause), can significantly affect quality of life, and often coexists with anxiety, sleep problems, and other centralized pain complaints. Evidence over the last decade points to small-fiber and central pain processing changes; for many people it behaves like other neuropathic pains. aaom.com+1

Other names

Doctors and dentists have used many names for this same problem. Common synonyms include glossodynia, glossopyrosis, stomatodynia, orodynia, oral dysesthesia, burning tongue, and sore mouth. These names refer to burning pain or changed sensation in the mouth or tongue without visible disease. PubMed+2OUP Academic+2

---

Types

Primary (idiopathic) stomatopyrosis / BMS.
This is burning of the mouth with no identifiable local or systemic cause after careful evaluation. The oral tissues look normal, and tests do not show a specific explanation. Scientists think it may relate to nerve dysfunction that changes how the mouth senses taste and pain. ICHD-3+1

Secondary stomatopyrosis / BMS.
This is burning of the mouth due to another condition. Examples include oral candidiasis, iron or vitamin deficiencies, diabetes, reflux, medication effects, allergic reactions to dental materials or foods, and Sjögren’s syndrome. When the cause is treated, symptoms often improve. Cleveland Clinic+1

---

Causes

Primary BMS has no single proven cause. The items below are common contributors or causes of secondary BMS-like symptoms that should be checked and treated when present.

1. Oral yeast infection (candidiasis).
   Thrush can irritate the tongue and mouth and create a burning feeling. A swab or culture can confirm it, and antifungals can help. Medscape

2. Dry mouth (xerostomia) or low saliva function.
   Dry mouth can make the tongue feel sore or burning and worsen taste changes. Salivary flow can be measured, and saliva substitutes or cause-based treatments may reduce burning. Cleveland Clinic+1

3. Acid reflux (GERD or LPR).
   Backflow of acid into the throat and mouth can irritate mucosa and cause a burning feeling. Treating reflux may lessen symptoms. Cleveland Clinic

4. Nutritional deficiencies.
   Low iron, folate, vitamin B12, zinc, or other micronutrients have been reported in people with burning mouth; correction can help some patients. BMJ Open+1

5. Hormonal changes (especially after menopause).
   Falling estrogen can change taste and oral pain perception, and BMS is more common in post-menopausal women. Cleveland Clinic

6. Diabetes or poor glucose control.
   High blood sugar and neuropathy can alter oral sensation and saliva, leading to burning symptoms. Medscape

7. Sjögren’s syndrome and autoimmune conditions.
   These can cause dry mouth, altered taste, and burning. Autoantibodies and salivary tests help identify them. Medscape

8. Medication effects and polypharmacy.
   Several drugs (including some antihypertensives and antidepressants) and multiple medicines together are associated with BMS symptoms in older adults; reviewing and adjusting medications may help. PMC+1

9. Allergic contact reactions to dental materials or flavorings.
   Allergy to metal, acrylics, or flavoring agents can cause burning; patch testing sometimes identifies triggers, and replacing the allergen can help. Ovid+1

10. Ill-fitting dentures or oral appliances.
    Mechanical irritation or allergic components in dentures may cause burning sensations that improve with adjustment or material change. Wiley Online Library

11. Psychological stress, anxiety, or depression.
    Stress can heighten pain perception and change oral habits like clenching, which can worsen symptoms; addressing mental health can help. MDPI

12. Teeth grinding or jaw clenching (bruxism).
    Clenching and grinding strain oral tissues and nerves, sometimes aggravating burning or tingling. Night guards and habit therapy may help. Cleveland Clinic

13. Mouthwashes with alcohol or irritating flavors.
    Alcohol-based rinses and strong mint/cinnamon flavors can sting or burn sensitive mucosa; switching to gentle products can reduce symptoms. Medscape

14. Neuropathic changes in taste and pain pathways.
    Research shows altered small-fiber function and taste nerve (chorda tympani) changes in many patients with BMS, supporting a neuropathic mechanism. ScienceDirect+1

15. Thyroid disease (hypothyroidism).
    Low thyroid function can affect mucosa, nerves, and saliva and has been linked to BMS-like complaints. Screening and therapy may help. Medscape

16. Anemia.
    Low hemoglobin or iron deficiency can cause tongue soreness, altered taste, and burning that improve with correction. Medscape

17. Geographic tongue and other benign tongue variants.
    These conditions can coexist and sometimes add to burning or tingling sensations in sensitive tongues. Cleveland Clinic

18. Dehydration and mouth breathing.
    Reduced moisture and airflow dryness irritate tissues and can trigger burning or dryness sensations. Medscape

19. Reactions to foods, spices, or additives.
    Some people react to acidic, spicy, or cinnamon-containing foods, which can cause or worsen burning. Elimination can help identify triggers. Cleveland Clinic

20. Infections other than candida (rare).
    Bacterial or viral infections of the mouth can sometimes burn; cultures or swabs help rule these out when suspected. NCBI

Diagnostic tests

There is no single “BMS test.” Diagnosis relies on your history, a normal mouth exam, and ruling out other causes. These are common tests clinicians use.

A) Physical exam–based evaluations

1. Comprehensive oral exam.
   The dentist looks carefully at the tongue, gums, cheeks, and palate to confirm there are no sores, white patches, ulcers, or other visible problems that could explain the pain. A normal exam supports BMS. ICHD-3

2. Salivary gland assessment at the chair.
   The clinician looks for pooling of saliva, mucosal wetness, and salivary duct flow to screen for dry mouth during the visit. Cleveland Clinic

3. Denture and bite evaluation.
   They check for sharp edges, friction, pressure points, and stability of dentures or appliances that could irritate tissues. Wiley Online Library

4. TMJ and muscle palpation.
   Gentle pressure on jaw muscles and joints to look for clenching-related tenderness that can aggravate burning sensations. Cleveland Clinic

5. Skin and mucosal inspection elsewhere.
   Looking for signs of systemic conditions (e.g., lichen planus, thrush, nutritional changes) that may present in or around the mouth. PMC

B) Manual or bedside tests

6. Sialometry (saliva flow test).
   Saliva is collected over a few minutes (resting and stimulated) to measure flow. Results help confirm dry mouth or show normal flow despite dryness sensation. Cleveland Clinic+1

7. Oral swab/culture or KOH smear.
   A swab checks for candida or other microbes; treating positive results may reduce burning. NCBI

8. Patch testing for contact allergy.
   Small amounts of suspected allergens (metals, fragrance/flavor agents, dental materials) are placed on the skin for 48–72 hours to look for immune reactions that might explain burning. Ovid+1

9. Taste testing (electrogustometry or simple taste strips).
   Taste thresholds can be measured; many BMS patients have altered taste sensitivity. Wiley Online Library

10. Reflux screening questionnaires or empirical trial.
    Simple symptom tools or a trial of anti-reflux therapy can help identify reflux-related burning. Cleveland Clinic

C) Laboratory / pathological tests

11. Complete blood count (CBC) and iron studies.
    Looks for anemia and low iron stores (ferritin) that can cause sore, burning tongue. Medscape

12. Vitamin levels (B12, folate, B1/B2/B6) and zinc.
    Deficiencies are reported in BMS and may improve with correction. BMJ Open+1

13. Glucose or HbA1c.
    Screens for diabetes or poor control that can contribute to neuropathic burning. Medscape

14. Thyroid function tests (TSH, free T4).
    Checks for hypothyroidism as a reversible cause. Medscape

15. Autoimmune tests when indicated (e.g., ANA, SSA/SSB).
    Used when Sjögren’s or another autoimmune cause is suspected due to dryness and other features. Medscape

16. Oral lesion biopsy (only if something looks abnormal).
    If the exam reveals a lesion, a small sample can check for conditions like lichen planus or dysplasia. BMS itself has a normal exam and does not need biopsy. Cleveland Clinic

D) Electrodiagnostic and sensory-function tests

17. Quantitative sensory testing (QST).
    Measures heat or mechanical pain thresholds on the tongue and lips; many studies show altered thresholds in BMS, supporting a neuropathic component. Nature+1

18. Electrogustometry.
    Applies tiny electrical stimuli to taste areas to measure taste nerve function; abnormalities can appear in BMS. Wiley Online Library

E) Imaging tests

19. Dental radiographs or cone-beam CT (when needed).
    Used to rule out dental disease, apical infections, or bony problems if symptoms or exam suggest a local cause. Cleveland Clinic

20. MRI or CT of head/neck (selected cases).
    Used when neurological causes are suspected or to exclude other pathology; imaging is normal in typical primary BMS. Cleveland Clinic+1

Non-pharmacological treatments (therapies & other measures)

1. Education & reassurance
   Understanding that BMS is real neuropathic pain—not infection or cancer—reduces fear. Education sets realistic goals (symptom control, not instant cure) and improves adherence to therapies. Mechanism: lowers threat-driven attention and catastrophizing that can amplify pain perception. NIDCR+1

2. Gentle oral care & irritant avoidance
   Use soft brushes; avoid alcohol-based mouthwashes, tobacco, and very spicy/acidic/salty foods during flares. Purpose: decrease mucosal irritation that can worsen burning sensations. Mechanism: reduces peripheral sensory triggering on already sensitized nerves. Mayo Clinic

3. Saliva support (hydration, sugar-free gum/lozenges, humidifier)
   Frequent sips of water, sugar-free gum/lozenges (xylitol), and a bedside humidifier can ease dryness and burning. Mechanism: moisture and gentle chewing stimulate salivary flow and dilute irritants. NIDCR

4. Over-the-counter saliva substitutes
   Carboxymethylcellulose or xylitol gels/sprays (e.g., “dry mouth” products) used as needed give temporary moisture and reduce friction during talking/eating. Mechanism: forms a protective film and retains moisture 1.5–4 hours. ADA+2Mayo Clinic+2

5. Cognitive-behavioral therapy (CBT)
   Short, structured sessions target rumination (“Why is this burning?”), sleep, and coping skills. Trials show CBT helps pain intensity and distress in BMS. Mechanism: reframes threat signals and reduces central pain amplification. PubMed+1

6. Brief group CBT / psychoeducation classes
   Group formats teach pacing, relaxation, and flare plans; they can improve pain and anxiety efficiently. Mechanism: shared learning and skills practice reduce attention to pain signals. J-STAGE

7. Relaxation & breathing (diaphragmatic breathing, progressive muscle relaxation)
   Simple home practices calm the autonomic system and can reduce “pain-volume” during spikes. Mechanism: lowers sympathetic arousal linked to heightened oral burning. PMC

8. Mindfulness-based approaches
   Brief daily mindfulness can decrease pain unpleasantness and improve sleep. Mechanism: changes attention and appraisal of oral sensations. PMC

9. Sleep hygiene
   Consistent sleep/wake times, reducing caffeine late day, and treating snoring or mouth-breathing can lower next-day burning. Mechanism: better sleep dampens central pain sensitivity; nasal breathing reduces oral dryness. Mayo Clinic

10. Nutritional correction
    Check and treat correctable problems (iron, ferritin, B12, folate, zinc, glucose/HbA1c). Purpose: remove secondary causes that mimic or worsen BMS. Mechanism: restoring nutrients supports nerve function and taste buds. NIDCR+2Office of Dietary Supplements+2

11. Topical clonazepam “melt & spit” (compounded) training
    Although clonazepam is a drug, the technique (placing solution/lozenge, bathing the area, and spitting out to minimize systemic exposure) is a non-systemic strategy your care team may teach. Mechanism: local GABA-ergic calming of hypersensitive mucosal nerve endings. PubMed+1

12. Capsaicin oral rinse protocol guidance
    Clinicians may supervise very low-dose capsaicin rinse titration for desensitization. Mechanism: repeated TRPV1 activation depletes substance P and reduces burning over time. PMC

13. Low-level laser therapy (LLLT)/photobiomodulation
    Clinic-based LLLT to the tongue/oral mucosa has reported pain reductions in some trials; often combined with other care. Mechanism: photobiomodulation may modulate small-fiber activity and local inflammation. PMC

14. Repetitive transcranial magnetic stimulation (rTMS)
    Specialist centers may offer short courses targeting prefrontal areas; RCTs suggest benefit for pain. Mechanism: non-invasive neuromodulation reduces cortical pain network hyperexcitability. SpringerLink

15. Taste training & zinc-friendly diet if indicated
    When dysgeusia is prominent and zinc deficiency is present, clinicians may pair diet changes with replacement. Mechanism: supports taste receptor function and reduces metallic/bitter taste that can amplify burning. Office of Dietary Supplements

16. Allergy/irritant swap-outs
    If contact allergy suspected (e.g., cinnamal, menthol, dental materials), patch-test guided substitutions may reduce triggers. Mechanism: removing allergens lowers peripheral nociceptor firing. PMC

17. Menopause symptom management (non-hormonal options)
    Hot-flash stabilization, mood/sleep care, and vaginal estrogen (if indicated) may indirectly help BMS comorbidities, though HRT itself generally does not fix BMS. Mechanism: addresses associated factors rather than BMS directly. maaom.memberclicks.net

18. Dietary pattern for nerve health
    Balanced protein, B-vitamin-rich foods, and hydration support nerve recovery; avoid very hot drinks. Mechanism: reduces thermal and chemical irritation while supporting micronutrients. NIDCR

19. Mouth-breathing/sleep apnea management
    Treat nocturnal mouth-breathing and OSA to reduce dryness-driven burning. Mechanism: improved nasal airflow and saliva preservation. Mayo Clinic

20. Self-management plan (flare card)
    A simple written plan (cool water, saliva gel, breathing exercise, short quiet break) lowers panic and pain spirals during flares. Mechanism: rapid, repeatable coping interrupts central amplification. NIDCR

Drug treatments

Important: Most medicines below are off-label for BMS; evidence quality varies (many small trials). Doses are typical starting ranges—not prescriptions. Always individualize with your clinician.

1. Clonazepam (topical or low-dose oral) – benzodiazepine
   Typical: 0.25–0.5 mg let-dissolve on the sore area for 1–3 minutes then spit, 1–3×/day; or 0.25–0.5 mg oral nightly. Purpose: calm hyperactive oral nerve endings and reduce burning. Mechanism: GABA-A modulation; topical minimizes systemic effects. Side-effects (systemic): sedation, dependence risk—avoid long-term oral use. FDA safety comes from clonazepam labeling. PubMed+2PubMed+2

2. Gabapentin – antiepileptic for neuropathic pain
   Typical: start 100–300 mg at night; titrate to 900–1800 mg/day in divided doses if tolerated. Purpose: reduce neuropathic pain. Mechanism: alpha-2-delta subunit binding modulates excitatory neurotransmission. Side-effects: dizziness, somnolence; caution with CNS depressants. FDA Access Data+1

3. Pregabalin – antiepileptic/neuropathic pain agent
   Typical: 25–50 mg at night; titrate toward 150–300 mg/day. Purpose: similar to gabapentin with sometimes faster onset. Side-effects: dizziness, weight gain; taper off slowly. FDA Access Data+1

4. Amitriptyline (low dose at night) – tricyclic antidepressant (TCA)
   Typical: 5–10 mg hs; slowly to 10–25 mg hs. Purpose: improve sleep and dampen neuropathic pain signals. Mechanism: serotonin-norepinephrine reuptake inhibition and sodium channel effects. Side-effects: dry mouth, constipation, QT risk—avoid in certain heart conditions. FDA Access Data+1

5. Nortriptyline (alternative TCA)
   Typical: 10 mg hs; titrate carefully to 25–50 mg hs if needed. Purpose/mechanism: as above with often better tolerability than amitriptyline. Side-effects: anticholinergic effects, QT risk; monitor. FDA Access Data+1

6. Duloxetine – SNRI with pain indications
   Typical: 20–30 mg daily, potentially 30–60 mg/day. Evidence for neuropathic pain relief may translate to some BMS cases. Side-effects: nausea, insomnia or sleepiness; black box for suicidality; note 2024 class II recalls for select lots (not a reason to stop abruptly—discuss with clinician). FDA Access Data+1

7. Sertraline (SSRI, selected cases)
   Typical: 25 mg daily then 50 mg; chosen when mood/anxiety drive symptom focus. Purpose: reduce comorbid anxiety/depression that can magnify pain. Side-effects: GI upset, sexual dysfunction; black box warning. FDA Access Data+1

8. Topical capsaicin (very low-dose rinse/gel under clinician guidance)
   Purpose: desensitize TRPV1 pain receptors in mucosa. Mechanism: repeated activation depletes pain neuropeptides. Note: the Qutenza® capsaicin patch is FDA-approved for PHN/diabetic neuropathy skin pain—not oral use—but its labeling informs capsaicin safety and handling. Side-effects: transient intense burning—must be guided. PMC+1

9. Lidocaine viscous 2% (short-term numbing before meals)
   Typical: dilute small amounts as directed; avoid overuse. Purpose: brief anesthesia for eating/speaking. Risks: rare systemic toxicity if swallowed excessively; special caution in children. FDA Access Data+1

10. Pilocarpine (Salagen®) for prominent xerostomia
    Typical: 5 mg two to three times daily (if dry mouth is a driver and no contraindications). Purpose: stimulate salivary flow in true hyposalivation. Side-effects: sweating, flushing; avoid in certain cardiovascular/respiratory conditions. FDA Access Data+1

11. Cevimeline (Evoxac®) for Sjögren-type dryness
    Typical: 30 mg three times daily (specialist guidance). Purpose: M3 agonist increases saliva; consider when dryness is central. Side-effects: sweating, vision changes; avoid in uncontrolled asthma, narrow-angle glaucoma. FDA Access Data+1

12. Clonazepam + LLLT combination (specialist protocol)
    Combining topical clonazepam with photobiomodulation can help some refractory cases; used in clinics with protocols. Mechanism: peripheral desensitization + neuromodulation. ClinicalTrials.gov

13. Alpha-lipoic acid (ALA) — see Supplements section; sometimes co-prescribed with gabapentin
    Trials show modest benefit; more in long-term assessment; quality varies. Use as adjunct, not a stand-alone “cure.” PubMed

14. Short trial of low-dose benzodiazepine nighttime use (e.g., clonazepam) for sleep-pain cycles
    Only as brief bridge therapy with clear exit plan; risk of dependence. FDA labeling underscores dependence/withdrawal warnings. FDA Access Data

15. SNRIs/TCAs switching strategy
    If one class fails or side-effects limit use, a cautious switch (e.g., from SSRI to TCA or SNRI) may help. This is individualized and relies on broader neuropathic pain data rather than BMS-specific labels. PubMed

16. Topical clonazepam solution (compounded) titration
    Pharmacy-compounded 0.5 mg/mL solutions under dental/OMFS supervision have retrospective and prospective support for pain reduction. PubMed+1

17. Pregabalin as second-line after gabapentin
    Chosen when gabapentin response is partial or intolerable; similar cautions on dizziness, edema, and tapering. FDA Access Data

18. Nortriptyline daytime micro-dosing
    Tiny daytime doses (e.g., 10 mg) may help some with constant burning; balance sedation vs. dryness. Monitor cardiac risk in older adults. FDA Access Data

19. Sertraline for comorbid panic/rumination that escalates burning
    Helps reduce attention to symptoms and improve coping; not a direct analgesic. Follow SSRI safety labeling. FDA Access Data

20. Duloxetine when allodynia and “centralized” pain dominate
    Chosen from neuropathic pain playbook with careful monitoring and shared decision-making. Be aware of recent manufacturing recalls in certain lots; don’t stop abruptly without medical advice. FDA Access Data+1

Systematic reviews find CBT, topical clonazepam, capsaicin, and certain laser approaches show the most consistent benefits; overall trial quality is variable, so multimodal care works best. PMC+1

Dietary molecular supplements

Supplements are adjuncts. Check interactions and lab status first; quality of evidence ranges from low to moderate.

1. Alpha-lipoic acid (ALA) 600 mg/day
   Description: An antioxidant cofactor studied most in BMS; several RCTs and meta-analyses show modest symptom improvement, sometimes increasing over months. Function/mechanism: antioxidant and small-fiber nerve support; may modulate mitochondrial and nociceptive signaling. PMC+2PubMed+2

2. Vitamin B12 (dose individualized; common oral 1000 mcg/day if deficient)
   Description: Correct deficiency to support nerve/taste function; deficiency is a known oral burning mimic. Function/mechanism: cofactor in myelin and DNA synthesis; deficiency can cause glossitis and neuropathy. Office of Dietary Supplements

3. Folate (dose per deficiency status)
   Description: Correct low folate when present to support mucosa and nerves. Mechanism: nucleotide synthesis and methylation pathways relevant to nerve repair. NIDCR

4. Iron (elemental iron per labs; e.g., 45–65 mg/day)
   Description: Treat iron deficiency/ferritin depletion that can worsen glossal burning and taste changes. Mechanism: supports epithelial and neural enzymes; corrects anemia-related hypoxia. NIDCR

5. Zinc (dose per RDA and labs; avoid excess)
   Description: Zinc deficiency can aggravate dysgeusia; careful replacement may help taste-related discomfort. Mechanism: cofactor for taste receptor and epithelial repair enzymes. Office of Dietary Supplements

6. Omega-3 fatty acids (EPA/DHA 1–2 g/day combined)
   Description: Anti-inflammatory support with general neuropathic pain plausibility; evidence in BMS is indirect. Mechanism: resolvins and membrane effects may reduce neuroinflammation. PMC

7. Vitamin D (dose per baseline level)
   Description: Low D is common in chronic pain; repletion may support neuromuscular function; evidence in BMS is indirect. Mechanism: neuroimmune modulation. PMC

8. Probiotics (strain-specific; exploratory)
   Description: Some patients with taste changes and burning report benefit; evidence is preliminary. Mechanism: gut–immune–neural crosstalk affecting inflammation and nociception. PMC

9. Coenzyme Q10 (100–200 mg/day)
   Description: Antioxidant/mitochondrial support; limited direct BMS data, occasionally used in neuropathic symptom programs. Mechanism: mitochondrial electron transport and oxidative stress reduction. PMC

10. Capsaicin capsules (very low dose, supervised)
    Description: Swallowed capsaicin has been used in phytotherapy trials; may reduce oral burning via central and peripheral desensitization; start only with clinician oversight due to GI side-effects. Mechanism: TRPV1 desensitization and substance-P depletion. ScienceDirect

Immunity-booster / Regenerative / Stem-cell drugs

There are no approved stem-cell drugs or “immunity boosters” for BMS. Below are evidence-based, legal medicines that support nerve function or dryness in specific situations; none “regenerate” nerves by themselves.

1. Pregabalin (see above): supports neuropathic pain control while nerves calm; mechanism: alpha-2-delta modulation; dose individualized. FDA Access Data

2. Gabapentin (see above): similar role; adjust dose to effect and side-effects. FDA Access Data

3. Amitriptyline/Nortriptyline (low dose): small nightly doses aid sleep-dependent nerve recovery and central pain down-regulation. FDA Access Data+1

4. Pilocarpine: in true hyposalivation, salivary stimulation protects mucosa and may indirectly reduce burning by improving lubrication. FDA Access Data

5. Cevimeline: similar saliva-stimulation effect, especially in Sjögren’s. FDA Access Data

6. Topical clonazepam: local GABAergic desensitization may allow peripheral nerve endings to “quiet” over time without systemic exposure. PubMed

---

Surgeries

BMS is a functional neuropathic pain without visible lesions; surgery is not recommended and offers no proven benefit. Dentists may adjust denture fit or replace irritating materials if contact allergy is confirmed, but that is not surgery for BMS itself. Any surgical idea (nerve section, biopsy beyond diagnosis) risks harm without evidence of benefit and should be avoided for primary BMS. NIDCR+1

---

Preventions

1. Keep regular dental and medical checks to spot treatable causes (thrush, deficiency, diabetes, medication effects) early. NIDCR

2. Use gentle, alcohol-free oral care; avoid tobacco. Mayo Clinic

3. Sip water often; use sugar-free xylitol gum/lozenges during long talking sessions. NIDCR

4. Limit very hot drinks and very spicy/acidic foods during flares. Mayo Clinic

5. Manage stress with brief daily relaxation or mindfulness. PMC

6. Protect sleep: consistent schedule; treat snoring/mouth-breathing. Mayo Clinic

7. Review medicines with your clinician (ACE inhibitors, SSRIs, etc.) if symptoms started after a new drug. NIDCR

8. Correct nutritional gaps (B12, iron, folate, zinc) when present. Office of Dietary Supplements+1

9. If you wear dentures, ensure fit and hygiene; remove at night. maaom.memberclicks.net

10. Create a written “flare plan” you can follow automatically. NIDCR

---

When to see a doctor

Seek care if burning lasts more than a few weeks, if you have dry mouth, taste change, tongue color change, weight loss, mouth sores, fever, or trouble swallowing, or if symptoms follow a new medication. Anyone with diabetes, Sjögren’s, thyroid disease, recent dental work, or nutritional concerns should be assessed early to rule out secondary causes before labeling it primary BMS. Urgent review is needed for progressive lesions, bleeding, severe pain, or systemic symptoms. NIDCR

---

What to eat and what to avoid

Eat more: cool water; foods at lukewarm temperature; soft proteins (eggs, yogurt); non-acidic fruits (ripe banana, melon); steamed vegetables; whole grains; B-12-rich foods if not restricted (fish, dairy, eggs); olive-oil-based dishes; sugar-free xylitol gum/lozenges to stimulate saliva; balanced meals to stabilize energy and stress. Office of Dietary Supplements+1

Avoid or limit during flares: very hot drinks; strong chili/pepper and vinegar; alcohol and alcohol-based mouthwashes; tobacco; highly salty or acidic snacks; cinnamon-flavored products if they sting; frequent citrus sucking; carbonated sodas; rough, dry crackers; very dry mouth-breathing at night (use a humidifier). Mayo Clinic+1

Frequently asked questions

1. Is BMS dangerous or cancer?
   No. It is painful but benign; the mouth usually looks normal. Doctors must first rule out other conditions before calling it BMS. NIDCR

2. What causes it?
   Likely a mix of nerve hypersensitivity (peripheral small fibers) and central pain processing. It can be “primary” (idiopathic) or “secondary” (due to another condition like deficiency, dryness, thrush, or medication). PMC

3. How is it diagnosed?
   By history plus a normal oral exam and tests to exclude mimics (CBC, iron/ferritin, B12, folate, zinc, glucose/HbA1c, thyroid, oral culture if needed). NIDCR

4. Will it go away?
   Some improve over months; others need long-term management. Early, multimodal care improves outcomes. PMC

5. Which treatment works best?
   Best evidence supports CBT, topical clonazepam, capsaicin protocols, and select laser/photobiomodulation—often combined with saliva care and sleep support. PMC

6. Are medicines a cure?
   No single cure exists. Neuropathic pain agents (e.g., gabapentin, pregabalin, TCAs/SNRIs) can lower pain; many are off-label in BMS. Benefits must be balanced with side-effects. PubMed

7. Is topical clonazepam safe?
   When compounded and spit out after mucosal bathing, systemic exposure is low; still, clinicians supervise and limit duration. Oral long-term benzodiazepines carry dependence risk. PubMed+1

8. Do vitamins help?
   They help only if you are deficient (B12, iron, folate, zinc). Testing guides dosing. ALA has modest evidence as an adjunct. Office of Dietary Supplements+1

9. Is hormone therapy useful for postmenopausal BMS?
   Generally no; HRT is not an established treatment for BMS itself. maaom.memberclicks.net

10. Can dry mouth cause burning?
    Yes. Treating true hyposalivation (e.g., with pilocarpine or cevimeline when appropriate) and using saliva substitutes can help. FDA Access Data+1

11. Does BMS damage the tongue?
    Despite severe burning, tissues are typically normal; the problem is sensory nerve signaling. NIDCR

12. Are capsaicin rinses safe?
    They can sting intensely at first and must be clinician-guided. Evidence suggests benefit with careful protocols. PMC

13. What about Qutenza® patches?
    They are FDA-approved for certain skin neuropathies, not oral use; they inform capsaicin safety concepts but aren’t applied inside the mouth. FDA Access Data

14. Could antidepressants help if I’m not depressed?
    At low doses, TCAs/SNRIs can reduce neuropathic pain independent of mood effects; your doctor weighs risks/benefits. PubMed

15. When should I seek urgent care?
    New ulcers, masses, bleeding, fever, difficulty swallowing, weight loss, or rapidly worsening pain need prompt evaluation to exclude other diagnoses. NIDCR.
