My upper veneer bite down over my lower teeth. I grind when sleeping. The 2 left veneer next to my left front tooth keep falling. I've been back to her office 4 times, those 2 fell out again (1 last week and 1 last night). Do I have a case here to ask her to pay for service from a more qualified dentist who may be able to perform bonding? Or regardless whether I grind or not, a dentist should still be able to do their work overcome this as part of the whole deal. Thanks.
