An orofacial pain specialist may help although I don't know for sure.
You may want to try the American Academy of Orofacial Pain and find a doctor through there.

I have been seen by a neurologist but not a orofacial pain specialist. I have seen primary care dr 2x - 3 diff dentists - 2 oral specialists & had several x-rays & an MRI & blood work. neuro guy says all looks ok - basically all agreed there can be non specific nerve pain that shows up after this but noone can figure out for certain or get me relief
Have you gotten a referral to an orofacial pain specialist?
