Oral and dental diseases include tooth decay (cavities), gum disease (periodontal disease), tooth loss, and oral cancer, which are largely preventable through good oral hygiene like brushing and flossing and professional dental care. These conditions can cause pain, difficulty eating and speaking, and can even affect overall health, being linked to heart disease, insulin is low or not working well. সহজ বাংলা: রক্তে চিনি বেশি থাকার রোগ।" data-rx-term="diabetes" data-rx-definition="Diabetes is a condition where blood sugar stays too high because insulin is low or not working well. সহজ বাংলা: রক্তে চিনি বেশি থাকার রোগ।">diabetes, and respiratory issues.  

Oral and Dental diseases refers to various conditions affecting teeth and gums, primarily tooth decay (cavities) and periodontal (gum) disease, both often beginning with plaque buildup from bacteria in the mouth. Other common issues include oral cancer, tooth loss, dry mouth, and oral thrush, which can impact speaking, eating, and overall well-being. Good oral hygiene, regular dental care, and managing systemic conditions like insulin is low or not working well. সহজ বাংলা: রক্তে চিনি বেশি থাকার রোগ।" data-rx-term="diabetes" data-rx-definition="Diabetes is a condition where blood sugar stays too high because insulin is low or not working well. সহজ বাংলা: রক্তে চিনি বেশি থাকার রোগ।">diabetes are crucial for prevention and treatment.  

Most oral health conditions are largely preventable and can be treated in their early stages. Most cases are dental caries (tooth decay), periodontal diseases, tooth loss and oral cancers. Other oral conditions of public health importance are orofacial clefts, noma (severe gangrenous disease starting in the mouth mostly affecting children) and oro-dental trauma.

Prevalence of the main oral diseases continues to increase globally with growing urbanization and changes in living conditions. This is primarily due to inadequate exposure to fluoride (in the water supply and oral hygiene products such as toothpaste), availability and affordability of food with high sugar content and poor access to oral health care services in the community. Marketing of food and beverages high in sugar, as well as tobacco and alcohol, have led to a growing consumption of products that contribute to oral health conditions and other NCDs.

Disease classification for the three major forms of periodontitis

The 2018 Disease Classification of Periodontal Diseases and Conditions breaks down the category of periodontitis into three forms and each of these forms are further broken down into two or more subcategories.

  1. Necrotizing periodontal diseases
    1. Necrotizing gingivitis
    2. Necrotizing periodontitis
    3. Necrotizing stomatitis

  3. Periodontitis
    1. Stages: Based on severity[a] and complexity of management[b]
      • Stage I: Initial periodontitis
      • Stage II: Moderate periodontitis
      • Stage III: Severe periodontitis with potential for additional tooth loss
      • Stage IV: Severe periodontitis with potential for loss of the dentition
    2. Extent and distribution:[c] Localized, generalized; molar-incisor distribution
    3. Grades: Evidence or risk of rapid progression,[d] anticipated treatment response[e]
      • Grade A: Slow rate of disease progression
      • Grade B: Moderate rate of disease progression
      • Grade C: Rapid rate of disease progression

Other conditions affecting the periodontium

The 2018 Disease Classification of Periodontal Disease and Conditions contains a category for other conditions that may have an effect upon the health of the periodontium.

  1. Systemic diseases or conditions affecting the periodontal supporting tissues
  2. Other periodontal conditions
    1. Periodontal abscesses
    2. Endodontic periodontal lesions
  3. Mucogingival deformities and conditions around teeth
    1. Gingival phenotype
    2. Gingival/soft tissue recession
    3. Lack of gingiva
    4. Decreased vestibular depth
    5. Aberrant frenum or muscle position
    6. Gingival excess
    7. Abnormal colour
    8. Condition of exposed root surface
  4. Traumatic occlusal forces
    1. Primary occlusal trauma
    2. Secondary occlusal trauma
    3. Orthodontic forces
  5. Prostheses and tooth-related factors that modify or predispose to plaque-induced gingival diseases/periodontitis
    1. Localized tooth-related factors
    2. Localized dental prostheses-related factors

Peri-implant diseases and conditions

The 2018 Disease Classification of Periodontal Disease and Conditions divides this category into four subcategories

  • Peri-implant health
  • Peri-implant mucositis
  • Peri-implantitis
  • Peri-implant soft and hard tissue deficiencies

Autoimmune Teeth Diseases

Doctor visit helper

Prepare before seeing a doctor

A simple rural-patient checklist to help you explain symptoms clearly, ask better questions, and avoid unsafe self-treatment.

Safety note: This is not a prescription or diagnosis. For severe symptoms, pregnancy danger signs, children with serious illness, chest pain, breathing difficulty, stroke-like weakness, or major injury, seek urgent care.

Which doctor may help?

Start with a registered doctor or the nearest qualified health center.

What to tell the doctor

  • Write when the problem started and how it changed.
  • Bring old prescriptions, investigation reports, and current medicines.
  • Write allergies, pregnancy status, diabetes, kidney/liver disease, and major past illnesses.
  • Bring one family member if the patient is weak, elderly, confused, or a child.

Questions to ask

  • What is the most likely cause of my symptoms?
  • Which danger signs mean I should go to hospital quickly?
  • Which tests are necessary now, and which can wait?
  • How should I take medicines safely and what side effects should I watch for?
  • When should I come for follow-up?

Tests to discuss

  • Vital signs: temperature, pulse, blood pressure, oxygen saturation
  • Basic physical examination by a clinician
  • CBC, urine test, blood sugar, or imaging only when clinically needed

Avoid these mistakes

  • Do not use antibiotics, steroid tablets/injections, or strong painkillers without proper medical advice.
  • Do not hide pregnancy, kidney disease, ulcer, allergy, or blood thinner use.
  • Do not delay emergency care when danger signs are present.

Medicine safety and first-aid guide

This section is for patient education only. It does not replace a doctor, pharmacist, or emergency care.

Safe first steps

  • Avoid heavy lifting, sudden bending, and prolonged bed rest.
  • Use comfortable posture and gentle movement as tolerated.
  • Discuss physiotherapy, X-ray, or MRI only when clinically needed.

OTC medicine safety

  • For mild back pain, pain-relief medicine may be discussed with a doctor or pharmacist.
  • Avoid repeated painkiller use if you have kidney disease, stomach ulcer, uncontrolled blood pressure, or are taking blood thinners.

Avoid these mistakes

  • Do not start antibiotics without a proper medical decision.
  • Do not use steroid tablets or injections casually for quick relief.
  • Do not delay emergency care because of home remedies.

Get urgent help if

  • Back pain with leg weakness, numbness around private area, loss of urine/stool control, fever, cancer history, or major injury needs urgent care.
Medicine names, dose, and timing must be decided by a qualified clinician or pharmacist after checking age, pregnancy, allergy, other diseases, and current medicines.

For rural patients and family caregivers

Patient health record and symptom diary

Write your symptoms, medicines already taken, test results, and questions before visiting a doctor. This note stays on your device unless you print or copy it.

Doctor to discuss: Doctor / qualified healthcare provider
Tests to discuss with doctor
  • Basic vital signs: temperature, pulse, blood pressure, oxygen level if needed
  • Relevant blood, urine, imaging, or specialist tests only after clinical assessment
Questions to ask
  • What is the most likely cause of my symptoms?
  • Which warning signs mean I should go to emergency care?
  • Which tests are really needed now?
  • Which medicines are safe for my age, pregnancy status, allergy, kidney/liver/stomach condition, and current medicines?

Emergency warning signs such as chest pain, severe breathing difficulty, sudden weakness, confusion, severe dehydration, major injury, or loss of bladder/bowel control need urgent medical care. Do not wait for online information.

Safe pathway to proper treatment

Care roadmap for: Oral and Dental Diseases

Use this simple roadmap to understand the next safe steps. It is educational and does not replace examination by a doctor.

Go to emergency care if you notice:
  • Severe or rapidly worsening symptoms
  • Breathing difficulty, chest pain, fainting, confusion, severe weakness, major injury, or severe dehydration
Doctor / service to discuss: Qualified healthcare provider; specialist depends on symptoms and examination.
  1. Step 1

    Check danger signs first

    If danger signs are present, seek emergency care and do not wait for online information.

  2. Step 2

    Record the symptom story

    Write when symptoms started, severity, medicines already taken, allergies, pregnancy status, and test results.

  3. Step 3

    Visit a qualified clinician

    A doctor, nurse, or qualified healthcare provider can examine you and decide which tests or treatment are needed.

  4. Step 4

    Do only useful tests

    Do tests after clinical assessment. Avoid unnecessary tests, random antibiotics, or repeated medicines without diagnosis.

  5. Step 5

    Follow up and return early if worse

    If symptoms worsen, new warning signs appear, or treatment is not helping, return for review quickly.

Rural patient practical tips
  • Take a written symptom diary and all previous prescriptions/test reports.
  • Do not hide medicines already taken, even herbal or over-the-counter medicines.
  • Ask which warning signs mean urgent referral to hospital.

This roadmap is for education. A real diagnosis and treatment plan requires history, examination, and clinical judgment.
