I had just the beginnings of trismus when I was in treatment. I noticed my mouth would only open maybe 2/3 to 3/4 as much as it did before cancer. My doc said I had to exercise the jaw, ie open it as much as I could, to the point of pain. He also said take your fingers and try to stretch it open even more.

I did this every day while driving to and from radiation treatment. Today, one year later I think I have normal mouth opening and closing. My dentist concurs when she examines my teeth.

take care, you will get there
