The denture is for my right maxillary molar, a relatively inconspicuous location, so I should be thankful for that. I had had a root canal for this tooth (and I don't even remember when.) Eventually the tooth had rotted off so all that was left was just the root. My previous dentist installed a jacket and that worked fine for a long time.
Jackets don't last forever, though. The first time it came off I was chewing through a piece of meat. it was disconcerting but a visit to the dentist put it back in its place. The damage was already done, though. The next it came off, it was embarrassing: I was sucking on a mint candy. The dentist told me if it came off one more time, there was no more putting it back. And indeed, the jacket came off a third and final time, because I was chewing on chocolate taffy.
