My left upper molar #14 started hurting a couple years ago, no one knew why, I had a root canal, it hurt very bad after that so I had it extracted. My gums
itch in that area, they are sometimes red and swollen around the tooth
behind the extraction area. My bite on that side is also WAY off. Can't chew on thay side, mu upper left teeth are very sensitive. Sometimes they ache. I also have ear pain and a sore
feeling on the left side of my face. Is this TMJ or some other problem?
