Dr. North has been my dentist for over 18 years. A few years ago, I moved to the other side of town and thought I would try a dentist closer to home. I went to one recommended by a friend and discovered I had 3 cavities,needed sealers and a host of other work. I called Dr. north and asked him for a second opinion. He said everything was fine. There was one spot we might want to keep an eye on, but it wasn't worth filling. That was over 5 years ago and I still haven't had that cavity. I highly recommend Dr. North.
