At Marana Dental Center getting my insurance claims was a nightmare. They messed up the paperwork repeatedly, I had 3 teeth crowned and they kept filling for the same tooth # 4 over and over again, never filling for teeth 5 and 6. So my insurance paid for one tooth. It took almost a year with my intervention to get it right. The lady who does insurance claims actually filled 13 times for the same tooth, which had already been paid for - she is completely incompetent.
As for Dr. Brewton, my 3 crowns are the worst I've had. And I have 3 other crowns for comparison. One hurts all the time. My current dentist says that I may end up needing a root canal on that tooth - and we must remove the cap and do it again. It has only been 14 months. Needless to say I was not impressed.
