Dr. Green was very attentive and did a thorough examination. It turned out that I did not actually have any gum problem and my dentist had erroneously attributed my toothache to gum recession. Dr. Green identified a crack in my filling and sent me back to my dentist to take care of it. He checked my tooth very carefully and identified the problem. The charge was only $40. His receptionist is very courteous, friendly, and helpful. I recommend this doctor based on my experience.
