John - I too got little benefit from the Thera-bite. Months of PT and painful exercises did almost nothing to increase the movement of my jaw. Like you, I had resigned myself to a tiny opening. My ent described the muscles like rubber bands before rad, and like shoe leather after rad. Poor me, stuck with a tiny mouth. Not even a large enough opening to insert a denture. Then I went back to teaching, talking alot, having to project my voice to the back of the classroom. Lo and behold, my jaw began to loosen.

My last radiation was in 9 of 03 and I am STILL recovering jaw movement! Its exciting and very encouraging. Don't believe for a moment that you are stuck forever with that limited motion. When the muscles are completely healed, they will begin to stretch a bit. With your encouragement and effort, you may still get more motion back. I'll never be Grand Canyon mouth again, but I am better than I was a year ago!!

Keep the Thera-bite. Its a great conversation starter..... Tom
