but don't wait. pick up the phone and ask your dentist.
we wouldn't know. please tell us what he said.
this doesn't sound normal.
ohhh, actually it may be. I just remembered that some materials, like composites shrink a LOT when exposed to cool not alone cold temperatures. What happens is that... well, Amalgam
is not bound to the tooth..it does not fall out because of the shape of the hole that was carved in your tooth by the dentist. It doesn't shrink much in the first place, but if it did, it would not pull the outer walls and the lower floor of the tooth together. Composites and porcelain fillings are bound glued to the tooth.
Some shrink like 3 or 4 times more than calcium hydroxy apetite and then they would pull on the tooth. This eventually leads to hairline cracks and eventually a crown as the tooth is cracked.
It all depends on the material he used. Very common problem for non Amalgam
type fillings. Even if he used a material that shrinks a lot hen exposed to cold... just don't eat cold things.
Easy. no need to drill again.
