I found this site and these posts because my husband has been experiencing the same thing with his gums. Over the last few weeks he has had terrible pain in his lower gum area (tongue side). This is alongside his wisdom tooth, which has never been removed and is currently being used to chew food. The dentist is totally puzzled, he has never seen anything like it before. He has pulled several bone-like shards out of my husband's gum. The dentist said it looks like bone to him. My husband's wisdom tooth was loose, and although his xrays look good, the dentist feels like the tooth is either dead or dying. Two days ago he performed a root canal on that tooth. He said he thought this would resolve the problem. It's been two days now and my husband is in such bad pain he can no longer stand it. I called the dentist and he is going to drill back open the tooth and drain it.
I know these posts are very old, but I would like to hear "the rest of the story" from previous posters.
Any help would be appreciated.
