Hey all,
Background:
My wife was having some minor tooth/jaw pain that slowly escalated over a period of 2 weeks. She then got a cold and subsequently a sinus infection. She began experiencing facial pain that was so severe we made a few trips to the hospital. After no diagnosis that seemed correct, doctors threw her on carbamazepine for TN. It may have worked, it is tough to say as she still wakes up in the night in pain (I think this is from grinding). The pain has now localized to one tooth and a number of dentists concur, the tooth is a problem. She has no feeling on one side (can't feel cold during the ice test), but pain when the ice is applied to the other side. They believe half of the root is necrotic and want to root canal or extract tomorrow.

She has been on antibiotics for 8 days now for the sinus and the pain seems to have subsided in the tooth. She is now hesitant to have the tooth worked on, but my feeling is that if the root has died something needs to be done anyways. TN can not be ruled out, and we can't say for certain if the carbamazepine has worked or the antibiotics have helped. I guess my question is, should she have the work done? Does this sound like a tooth related issue? The pain was always face and teeth and jaw and eventually localized to the tooth. At night, possibly after grinding the bad tooth, she wakes up with pain in the upper jaw and the sinus above. Sound like a tooth thing, or is there more going on here?

Thanks!
