Hi, I'm hoping someone can guide me with my recent problems. I had a lower molar crack & then break 2 yrs ago. I had root canal and then a crown. Everything was great until the last few months when the crowned tooth became hyper sensitive and impossible to chew on. At the same time teeth on the opposite side upper and lower are all hyper sensitive to cold. Off to the dentist I went, had the exam and multiple x-rays. She said their was no infection, no decay, nothing she could causing pain (which was significant at the time). She said only thing she could see was that one of the root canals was slightly too deep?? She suggested leaving it alone and see if it settled. As it was a couple of days before Christmas I agreed. I have avoided chewing on the side with the crown, but it is still very sensitive to touch and the hyper sensitivity continues on the opposite side.

My question is, should I just have this tooth removed? Is that the only option? I have a very small mouth and never got wisdom teeth, also had my largest molars removed as a teen to make room for the wisdom teeth that never arrived? I am 52, and don't really want to take the tooth out unless absolutely necessary. Any assistance would be great thanks.
