Dr. Chao did a very extensive examination and then charged me $3500 for what turned out to be, basically, a lot of tooth cleaning. In the meantime, I had very extensive problems including persistent infection which eventually required oral surgery and an extraction. Dr. Chao lead me to believe that spending all of this money for tooth cleaning (root planing performed by a dental hygienist) would resolve wobbly teeth and a lot of other problems. It didn't. I don't think he caused any harm he just charged me a lot of money for a treatment that was near certain to be ineffective. I left with the feeling that he is mostly interested in making money and not much interested in actually correcting or preventing problems.
