I am the sax and woodwind player. Glad to have heard from another woodwind player. I also get pain in my teeth as you describe, also jaw, toungue, lip, face. I am going to try getting as close to eliminating caffeine, chocolate, nuts, and saturated fats as I can to see if diet helps, as I have heard that it does. My job in the West Point Band's Jazz Knights for 14 of my 23 years in the Army was performing baritone sax.
