He overlooked some pretty extensive cavities I've obviously had for a while (they didn't hurt so I had no idea since I was getting regular six-month cleanings and check-ups for years). I don't think he was very thorough with his x-ray examination. He was much more concerned with lightening my front tooth than the vital stuff. He was also very rude to me and canceled an appointment I had after I was already sitting in the chair with my mouth prepped. I found it unprofessional, to say the least, and irritating because he apparently found my time much less valuable than his (I'm a cost accountant and I missed work during a really busy time for that canceled appointment). I may be the exception to the rule, but I did not have a good experience with Dr. Dunlap.
