I had restorative work done one lower left side. Since I have jaw pain and constant headache. My teeth hurt on top and bottom of that side. Saw another dentist he said my bite was off and he tooth down the tooth. I still have pain. I have been treated for sinus infection and TMJ with no success. I am now grinding at night and have cracked a crown on upper left side. I have no cavities or infection in my teeth. It has been a month. At first it would bother me after I ate. Now I just have a constant headache with some jaw pain and teeth hurt. Can you help me??
