tn is a shooting lighting like pain in one of three plces on your face. the nerve has 3 branches so your lower line of your jaw, the midline of your cheek or your tepmle and cheek. the pain comes in waves lasts for a few min and stops then comes back, over and over again. eating is a problem. it sets it off. if it were dental i'm not sure what to tell you to look for on that. because mine was tn and not dental. tn is hard to dx dr can only go off what you tell them you feel. and by what drugs do and don't work. i am not an expert just a pt. hope you start feeling better-shelly
