There is a certain risk of nerve damage when wisdom teeth are extracted very close to the nerve, and the most common damage to the inferior alveolar nerve is when the mandibular third molar is extracted, as described below. If the wisdom teeth are very close to the nerve, most of the damage to the nerve during extraction is due to the compression of the nerve by the instruments, resulting in edema of the nerve. Incomplete numbness of the skin of the lower lip and chin, or abnormal sensations such as burning and tingling, usually occur after injury to the inferior alveolar nerve. After regular treatment, the inferior alveolar nerve injury can mostly be recovered within six months, while some patients cannot recover, but the area of numbness usually shrinks and some pain sensation is restored. It is recommended to visit a regular medical institution to receive professional treatment.
