I have two teeth, molars, on the right side of my mouth. One is on the top and the other is on the bottom. I've had them for a couple of years now, but they are starting to cause some serious pain. I really don't want to pull them, but a rootcanal seems scary. I don't even know what they do for a rootcanal, and will that help at all? I just wanted to know what the best course of action would be for my situation?
