Relating 2 my other q you asked who i seen a oral surgeon he said its atypical facial pain but 1 tooth hurts wen i drink cold fluids@sounds hollow ?

Check that tooth: Have your regular dentist thoroughly check that tooth... May have a carious lesion that the oral surgeon did not pick up.

Many Causes: Without more info, it is impossible to diagnose your condition, but you may want to look more closely at the one tooth. A definite possibility is that the tooth has an undiagnosed carious lesion (cavity), that has possibly gone into the nerve space (canal). This could be the reason for the "hollow" feeling. If this is the case, it must be addressed asap.

See Endodontist: Endodontists are experts in diagnosing head and facial pain. A place to start are pulp tests, and other tests they perform to rule out a dental origin for your pain. If no tooth is found to be causing the pain, then other causes are looked for, such as neuralgia, neuritis, or other medical conditions. The doctor duplicating your pain will allow for proper diagnosis and treatment!

Same: The symptoms of a tooth and atypical facial pain can be the same and make diagnosis more challenging. Keep working with a dentist that is familiar with both to get a good diagnosis and treatment.

Endodontist: See an endodontist. Get another oral surgery opinion. If you end up with the diagnosis of atypical facial pain, see an orofacial pain specialist.
