I was eating and felt something odd in my food. It was the gold cap off my back tooth with part of my tooth. The tooth broke off at the gum line. I am sure I have had a root canal on this tooth. I am not in any pain. I have a tooth behind it and have had the wisdom tooth out. I have had trouble with this tooth and the one behimd it numerous times. I am 57 yrs old. What do I need to do?
