I'm not sure what you mean here lol!!
It shouldn't be flat it should still have been built up with cusps, a crown sounds like it would be better, but given the tooth behind has had RCT on it, that will need a crown too.
Can you ask around for recommendations for a new dentist???
Yeah de going to ask for a new dentist!
Tooth that has the filling fall out and replaced... Nope hasn't been built up with cusps and no mention ever of a crown on it. It's literally how I described it.... It's flat she literally drilled away then flattened it with a filling. I'll definitely be asking a new dentist for another opinion on those teeth if they can be fixed with a crown etc.
