I was having sensitivity to a molar for about 2 years. The dentist tried to 'save' the tooth by giving me a coating on the tooth. It helped for a while, but then the sensitivity increased, and eventually there was pain while chewing. I was advised to get a root canal. While trying to do the root canal I was extremely uncomfortable even though I was given three shots of anesthetic. She explained that she was able to clean out one canal but two were so inflamed that she could not get the anesthetic into the area. She closed the tooth and told me to come back in two days, the pulp would be dead. Went back and even after three shots of anesthetic still they could not touch the tooth without extreme pain up the side of my head. She gave me an antibiotic, but after three days on it I still can not get through a day without taking some kind of painkiller. Is this normal?View Thread
