If it is nerve pain, you should see either an oral facial pain specialist or a neurologist. I personally would recommend an oral facial pain specialist as they deal with that in particular. But either one is good.
The oral surgeon said it was not my teeth and said he thought it might be nerve pain. I am really worried becaue i have read horro stories with this type of pain. have you ever heard of this before. I have a constant toothache and can range from either side and intensity of pain.,
Well, if the ENT says it not a sinus problem, it probably isn't although your description definitely sounds like it would be a sinus problem. Sometimes I'll prescribe antibiotics before sending a patient to the ENT, especially if they have any nasal symtpoms prior to their pain. Do you have pain when leaning over or pain to pressure being applied on your cheek/eye area? I hate to contradict what your ENT has said since he/she has seen you and done a scan but judging by what the endodontist and the general dentist indicate, it seems there isn't a source of tooth pain.
