Wisdom Teeth Removal: Indications and Necessity

When Third Molar Extraction Is Recommended

Not all wisdom teeth need removal. Extraction is indicated when risks of retention outweigh surgical risks.

Common Indications

Impaction: Partial or full bony/soft tissue impaction → pericoronitis, caries, cyst, damage to 2nd molar.
Pathology: Cysts, tumors, infection (pericoronitis, cellulitis).
Caries/Periodontal Disease: Non-restorable decay or bone loss affecting adjacent teeth.
Orthodontic/Prosthetic Reasons: Interference with alignment, denture placement.
Prophylactic (Controversial): Asymptomatic, disease-free impacted teeth—evidence insufficient for routine removal (AAOMS, NICE guidelines vary).

Decision Factors

Surgical Risks

Nerve injury (IAN, lingual) – temporary/permanent paresthesia.
Dry socket (alveolar osteitis).
Infection, bleeding, sinus communication (maxillary).
Jaw fracture (rare, deep impactions).

Shared Decision-Making

Discuss with oral surgeon: imaging (panorex/CBCT), risks/benefits, anesthesia options, recovery timeline. No universal mandate for asymptomatic teeth.
