I had a canal done on my lower right first molar ten years ago. For the past month, I have been having an off and on pain in the tooth. The dentist said nothing wrong showed on the x-ray. Since the pain continued, he referred me to an Endodontist.
The also took x-ray and said there could be an infection in there. He went in and cleaned it up. The pain did not stop so I went back to the Endodontist. He said the tooth should be extracted now because of a possible hidden infection, which is causing the pain. Is it possible that an infection does not show up in the sometimes? Should I have this tooth pulled or get a second opinion? Any advice? Thanks so much.
