I am very impressed with Dr Lazerson. I had to have tooth number 4 removed, it was an old root canal that had been infected for years, but was sitting dormant. I did not know this tooth was causing a lot of problems until it started to really hurt. I did not know but this root canal had been causing me to have headaches and sinus problems for years. After the tooth was removed all my symptoms went away. Dr Lazerson is very proffesional and a kind Doctor. Thank you Robert Edwards, Marietta
