Just a question, the tooth where I had the root canal done roughly 10 months ago, it's the one right up the top back left hand side, should it be tender to touch still ? When the dentist did the percussion test a few weeks ago it was the only one that hurt on that side & when he probed inside it with a instrument it was real sensitive, he didn't really seem to want to know much about that though, it's also tender to touch by finger. Just wondered if this meant something wasn't right in there or that's normal for a tooth that had a root canal done ?

Kind regards Mark
