A good dentist I'm sure, but difficult to deal with. A couple of years ago she decided to no longer take United Healthcare insurance even though she was under contract with that insurer. We did get it straightened out, but it took awhile. Today she refused to allow the hygienist to clean my teeth because she wanted to take a set of prophylactic X-rays. I refused since my primary care dentist is in Washington State and I have all my prophylactic X-rays done there. I had some X-rays taken in September 2021 but they were not good enough for Dr. Schmahl. I told her that she could take an X-ray if she saw something suspicious in her exam, but that was not good enough. The only reason I go to her is to maintain a relationship so if something happens dental-wise in AZ, I have someone to go to. I would only let her do emergent work. But she would not listen and refused my cleaning. Never again. It should be noted that I have very good dental health and have only had one cavity filled in the last 20 years. read more
