Go back: And have it checked. 6 months later all should be well with that tooth. Please be ready to describe the pain as sharp or dull, constant or intermittent. If anything makes it better or worse, etc.

Perio or Endo: The way i understood the question: a root canal was done on a tooth with an old crown and there is now pain 6 mos after which wasn't there in the first place prior to the procedure. Please correct me if i misunderstood the question. Rct is recommended on a tooth which nerve is either dying or is already necrotic. In this case, there's a possible periodontal or endodontic reinfection or both.

See your dentist: You are having a recurrent infection, you need to go back to the dentist and have him check it again, if you did not have a new crown placed you may be having bacteria going back under the tooth and causing a new infection. Best of luck.
