I got a crown on a tooth that they have rejected for payment. Their "expert dentist" looked at x-rays and said I needed periodontal work in my whole mouth before they would pay. I got actual measurements taken over my mouth which proved him wrong. My dentist also says that at my age the healing time after the work they insist he do could easily cause more problems than they solve even if I did really need it. What they requested was "state of the art" years ago. Perhaps their "expert" should get refresher courses or retire.
