My back crown just came off but there's no pain. Why not? Never had a root canal.

Apparently the nerve must not be exposed but you do need to go see the dentist .

Yes but “seeing the dentist” and you’re talking thousands of dollars @janbb. If it were hundreds of dollars I’d call him now. He’d expose that nerve in no time. He’d drill that silver thing all out , do a root canal ($1,000 +) then put on a new crown ($1,000). Which would pop off like the rest of them do. Then he charges more to replace it. They don’t “just glue it back on” anymore.

@Aster the other option is go to local Dental school and have them “pull the offending” object out.

A crown is used when the tooth was too damaged to just fill. You usually get one after a root canal because they need to drill out a lot of tooth to get to the root but if the tooth was damaged in another way (very large cavity for example) then a crown is used to protect what is left. I imagine the silver thing is the peg that the dentist built up to securely seat the crown on. Basically its all that’s left of the original tooth. The crown is there to protect the peg because it is much softer than the material they make the crown out of. It doesn’t hurt to chew now because the peg is still protecting the nerve but sooner or later it will crack and you will know about it. The glue used to bond crowns doesn’t last forever and 10 years is a pretty good run. If you still have the intact crown then your dentist should be able to re-bond it to the peg, however if you leave it too long the peg will change shape and the crown wont fit any more and you’d need a new a crown. Basically the longer you leave it the more expensive its going to be to fix.

The silver thing is the build up- what they place to make the crown fit when there’s not enough tooth left. They can probably re-cement it.

Yes, as our Jelly dentist, @trailsillustrated, said, a re-cement is likely all you need.
