Had a root canal (abscess) about 5 years ago on my upper molar (#14, I think). This tooth had previously been crowned. In short, the dentist's file broke off in my tooth (pretty far into the procedure) and he was unable to retrieve it. He reattached the crown and informed me that I may or may not have future problems. It never felt completely 100% normal, but wasn't painful...until today! Now it is sending me into orbit! I cringe at the thought of losing any teeth.
Is the only way to get rid of this infection to pull this tooth?
What will my options be?
Could the solution be as simple as an antibiotic prescription?
