Chris - Thanks for that reminder about stretching exercises. My surgeon or prosthodontist didn't initally give me anything. When I saw my oncologist for the first time he became concerned. I was only able to open my mouth about 14cm. He immediately order a thera-bite and I began exercises 3 -4 times a day. I made good progress up to about 22cm, and then got stuck! I can't seem to do more. Any other suggests? They suggested doing it more often but when you are in pain anyway it is hard to subject yourself to more pain.
