Thanks for the response. I had primary surgery on lower right side - removed about 4 lower back teeth, shaved jaw and did a tongue flap to cover - I had no real residual pain after surgeries - all from radiation (and yes brushing my teeth and using Therabite and when hitting tongue right side also causes real pain). I had IMRT 33 days/treatments to entire oral cavity (both sides of mouth) - from parotids (caught part of them) down to my adam's apple; I also had amifostine injections during treatment (supposed to decrease residual mucositis).
