Wisdom Teeth Removal: Understanding the Importance and When It's Necessary

Not everyone needs wisdom teeth (third molars) extracted. Indications for removal include:

• Impaction: Tooth fails to erupt fully—mesioangular, vertical, horizontal, or distal. Risks: pericoronitis, caries, periodontal defects on adjacent tooth.
• Crowding/orthodontic relapse: Pressure on second molars may shift alignment.
• Infection: Recurrent pericoronitis, abscess, cellulitis.
• Cyst/tumor: Dentigerous cyst, ameloblastoma (rare) associated with impacted tooth.
• Damage to adjacent teeth: Resorption of second molar roots.
• Prophylactic: Some surgeons recommend removal in late teens/early 20s before roots fully form (easier surgery, faster healing).

Decision factors: Age, impaction type, symptoms, pathology, patient preference, anesthesia tolerance. Panoramic or CBCT imaging guides planning. Asymptomatic, fully erupted, functional, and hygienic wisdom teeth may be retained with monitoring.
