Dr. Knight did a few of tooth amputations for me. He is incredibly professional and is very gentle and caring. He follows up on each surgery carefully for years afterwards. He does all these monitoring startng from every 3 month and then 6 months and then annually for a few years. Each monitoring examination takes about 10 minutes but does it free of charge. Dr. Knight is the best doctor I have ever met in my life. I wish every doctor is like Doctor Knight and we will all have peace fo mind about our health!
