Reworking a root canal
5 replies 116 views
About 15 years ago I had root canal work on a lower jaw molar tooth, with the nerves removed, filler inserted, and a gold crown on top. Today I had xrays done and the dentist said there was a light area just below the crown, and just below the end of the tooth. I saw the xrays, and confirm what was said. He said this suggested bone loss due to bacteria, and the tooth needed to be reworked ie replace the old filler inside the roots, and add a new crown. Does this sound plausible? I generally trust my dentists, but I’m curious how bacteria can get inside the filler inside the tooth roots, and given the high cost, I’d like to understand the rationale.
