[|AI|]  Hi, thanks for your query. There are several issues that can cause your lip, chin, or jaw to be numb after a root canal procedure. The first is that, in the process of filling the space normally taken up by your tooth pulp, the dentist has used too much filling material. Doing this sometimes results in the material penetrating to the main sensory nerve and chemically burning it. It is very common for overfill in rear teeth to cause lip and chin numbness. Once infection is present from perforation, however, medications may work, but if the problem gets bad enough, extraction might become necessary for you, just as it is with infection from under filling. Visit endodontist for this. Hope this is helpful.
