Also known as a third molar, is the third molar back, and usually has 2 or more roots. There is often not enough space in the dental arch, often leading to impaction and non-function. This makes them difficult to access for hygiene, predisposing them to dental and periodontal complications, including causing damage to adjacent teeth. Wisdom teeth are unique in that their anatomy is highly variable, including the number of roots and their proximity to critical anatomy like the maxillary sinus, inferior alveolar nerve and lingual nerves.
Oral and Maxillofacial surgeons have extensive training to identify and mitigate these risks for their patients.
