About 5 or 6 years ago when I was in middle school, I had to have a root canal on one of my bottom teeth. since then I have gotten braces put on and taken off my teeth. I still have a wire on the back of my bottom teeth. I have never had an actual problem with my root canal. Recently im starting to feel soreness and at sometimes intense pain starting from where my lower lip and lower gum meet to the starting of the top of my chin. I hurts to put pressure on it. When i put pressure on it , it sends a pain sensation through, I guess, My nerves to one of my teeth. I was thinking it might be because the wire on the back of my lower teeth had came off but im starting to think otherwise. Also i thought about this new found pain to be related to my root canal i had 5 or 6 years ago, but the strange thing id that the pain sensation is going to another tooth instead of the one I had a root canal on. It also hurts when I make facial expression that involve my muscles uncle my lower lip. (example: when going to kiss). To my knowledge I have not hit this area that is sore to make it hurt.
