I just finished a root canal with Dr. Cannon. I had heard from co-workers how awful a root canal was. I kept waiting for the pain. It was a breeze. The tooth was a bit sore after the numbing medicine wore off, however I did not even need to take Tylenol. I have had a couple of fillings done by Dr. Cannon in the past. I am very happy with his services. I find his staff very nice and would recommend him to anyone.
