Long story, but to summarize:
I had a root canal, went in a couple weeks ago to have it prepped for a crown. The dentist was worried at first cuz there is a crack in the tooth, but after working on it he figured it was salvageable and he put some kind of rubber stuff around the gum line and temporarily capped it to get the crown in a couple weeks.
I was chewing something a couple minutes ago and the entire top of my tooth came off. Now it's a nub about 1/4 inch (totally guesstimating that). No pain, and it's all sealed up.
Is there any salvaging this, or is it gone?
