Damage to the inferior alveolar nerve is a risk of lower wisdom tooth removal (and other surgical procedures in the mandible). [20] This means there is a risk of temporary or permanent numbness or altered sensation to the lip +/- chin on the side the surgery is taking place.
Coronectomy should be considered if there are signs that the patient is at a high risk of nerve damage during extraction: Lower wisdom tooth is shown to be close to the inferior alveolar canal radiographically: [6] Signs of narrowing or diversion of the canal; Roots are darkened/ Canal is interrupted; Interruption of lamina dura
Temporary and permanent inferior alveolar nerve (IAN) damage is a known complication of the surgical removal of impacted lower third molars, happening in 1 in 85 patients and 1 in 300 extractions, respectively. Studies have shown that certain risk factors may increase the likelihood of IAN damage.
This risk increases 10 fold if the tooth is close to the inferior dental canal containing the inferior alveolar nerve (as judged on a dental radiograph). [8] These high risk wisdom teeth can be further assessed using cone beam CT imaging to assess and plan surgery to minimise nerve injury by careful extraction or undertaking a coronectomy ...
The most common treatment for recurrent pericoronitis is wisdom tooth removal. The risks of wisdom tooth removal are roughly proportional to the difficulty of the extraction. Sometimes, when there is a high risk to the inferior alveolar nerve, only the crown of the tooth will be removed (intentionally leaving the roots) in a procedure called a ...
The most common location of dry socket: in the socket of an extracted mandibular third molar (wisdom tooth). Since alveolar osteitis is not primarily an infection, there is not usually any pyrexia (fever) or cervical lymphadenitis (swollen glands in the neck), and only minimal edema (swelling) and erythema (redness) is present in the soft tissues surrounding the socket.

Facial nerve branches. Facial nerve should be examined for any potential damage when buccal mucosa is involved. Soft tissues injuries are presented commonly in association with dental trauma. Areas normally affected are lips, buccal mucosa, gingivae, frenum and tongue. The most common injuries are lips and gingivae.
