Mobile Teeth: Pathology, Grading, and Management
Tooth mobility refers to the degree of movement of a tooth in its socket. While a slight degree of physiologic mobility is normal (especially in anterior teeth), increased mobility usually indicates underlying pathology.
๐ฆท I. PATHOLOGY OF MOBILE TEETH
1. Physiological Mobility
-
Slight movement (up to 0.2 mm) is considered normal.
-
Due to periodontal ligament elasticity.
2. Pathological Causes
A. Periodontal Causes (Most common)
-
Chronic periodontitis: destruction of periodontal ligament and alveolar bone.
-
Acute periodontal abscess
-
Trauma from occlusion (TFO)
B. Periapical Pathology
-
Apical periodontitis
-
Periapical abscess
C. Traumatic Causes
-
Dental trauma (accident or sports injuries)
-
Bruxism (grinding of teeth)
D. Orthodontic Treatment
-
Excessive or uncontrolled orthodontic forces
E. Systemic Conditions
-
Osteoporosis
-
Diabetes mellitus
-
Leukemia
-
Hormonal changes (e.g., pregnancy, menopause)
F. Neoplastic Conditions
-
Malignancies invading jawbones
G. Iatrogenic Causes
-
Over-instrumentation in endodontics or surgery
๐งช II. GRADING OF TOOTH MOBILITY (MILLER'S CLASSIFICATION)
| Grade | Description |
|---|---|
| Grade 0 | Normal mobility (physiologic) |
| Grade I | Slight mobility (<1 mm in horizontal direction) |
| Grade II | Moderate mobility (>1 mm but <2 mm in horizontal direction) |
| Grade III | Severe mobility (>2 mm in horizontal direction and/or vertical mobility – i.e., depressible in socket) |
๐ ️ III. MANAGEMENT OF MOBILE TEETH
A. Diagnosis & Investigations
-
Complete history & clinical examination
-
Radiographs (IOPA, OPG)
-
Periodontal probing
-
Occlusal analysis
-
Blood tests (CBC, glucose, HbA1c if systemic cause suspected)
B. Management Based on Cause
1. Periodontal Therapy
-
Scaling & Root Planing: To remove plaque and calculus
-
Periodontal Surgery: Flap surgery, regenerative procedures if bone loss is present
-
Splinting: Temporary or permanent splints to stabilize mobile teeth
-
Occlusal Adjustment: Eliminate traumatic occlusion
2. Endodontic Therapy
-
RCT if mobility is due to periapical pathology
3. Orthodontic Correction
-
Re-evaluate and reduce excessive orthodontic forces
4. Restorative Measures
-
Replace missing adjacent teeth to distribute occlusal load
-
Crown placement to reinforce structure (in certain cases)
5. Extraction
-
Grade III mobility with severe bone loss and hopeless prognosis
6. Treatment of Systemic Causes
-
Diabetes control, hormonal therapy, managing osteoporosis
-
Hematological evaluation for leukemia if suspected
๐ชท IV. AYURVEDIC VIEW (Optional - if needed for integrative practice)
In Ayurveda, mobile teeth can be considered under "Danta Chala" – a symptom seen in diseases like Dantaharsha, Dantashotha, and Asthigata Rogas.
Management may include:
-
Gandusha/Kavala: Oil pulling with Tilataila or medicated decoctions (e.g., Triphala)
-
Dantadhavana: Herbal tooth powders (Triphala, Lavanga, Saindhava, etc.)
-
Local lepa or pratisarana with astringent herbs
-
Rasayana Therapy: Ashwagandha, Shatavari for bone health
-
Asthidhatu Vardhaka Chikitsa: Use of Laksha, Guggulu, Shankha Bhasma, etc.
๐งพ V. PREVENTION AND MAINTENANCE
-
Good oral hygiene (brushing, flossing, mouthwash)
-
Regular dental check-ups
-
Control of systemic conditions
-
Night guards in bruxism
-
Balanced occlusion
-
Adequate calcium and Vitamin D intake
