Dr. Cuellar is a very nice lady. She is a very poor dentist. I have a very ill fitting crown that fit poorly from the day that she cemented it in. I have consulted with another dentist, and he agrees that it needs to be redone. This second dentist does not do crowns, so he has no financial incentive to recommend another crown. Any dentist should have seen how poorly this crown fit and returned it to the lab that made it. Food sticks between my gum and the crown. I should have known better when I was consistently the only patient in her office.
