Patients can choose the appropriate treatment method according to their own situation and the doctor’s suggestion. 1. Clinical observation: the damage to the nerve caused by tooth extraction is mostly transient, and the nerve may be pressed or touched in the process of tooth extraction. After the anesthetic, there is numbness of the lips and tongue. Generally with the healing of the wound will be able to recover naturally, without special treatment. 2. Medication: Methylcobalamin tablets, vitamin B12, vitamin B1 and other nutritive nerve drugs can be used to help nerve function recovery. If the numbness is gradually reduced, it means that the damage is gradually recovering. 3.
