Also known as a third molar and usually has 2 or more roots. There is often not enough space in the dental arch for these teeth to erupt resulting in the wisdom teeth being impacted and non-functional. This makes them difficult to access for hygiene, predisposing them to dental and periodontal complications, causing damage to adjacent teeth and their surrounding bone. 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.
