I am 26 and have not been to the dentist is years. My teeth have been find up until a few months ago where one of my back molars where starting to hurt. I am not sure if it is a cavity or more and worry that I may need to have a root canal done. What are some of the signs to having to have a root canal. And if I do need a root canal are there any complications I should know about before having one done?
