A month or two ago the top of one of my teeth (lower middle-right) broke off. It didn't hurt. I'm not having a problem with it, but my wife is concerned that if I don't get it "taken care of" (whatever that means), I will end up with an abscess. Is this a valid concern? If I do see a dentist about it, what is
he likely to do - put a cap on it, or...?
