He spotted that a filling in one tooth was getting loose when I had a routine dental exam in mid-August, and recommended a replacement. When I confirmed with him that it wasn't in need of immediate replacement, I put it off until after NASFiC. He does say that the tooth in question will probably need a crown someday, as it actually has two fillings in it and a hairline crack connecting them, but for now he'll just keep an eye on it at each check-up.
