I was given a series of exercises early on by my Speech/Language Pathologist to do during and after treatment. While I definitely experienced some stiffness and range of motion issues, they were relatively minor and short lived. That being said, I still do them at least twice a day 11 weeks post treatment to keep things loose.
Keep up with the exercises! Opening your mouth as wide as you can, placing (up to) three fingers in and gently forcing it open and holding for 10 seconds, repeat ten times. Opening your mouth as wide as you can and moving your jaw left then right, ten repetitions. Same thing with mouth closed. Those were a couple that made a big difference in the long run.
The Therabite is a mechanical device that replaced the fingers in the above exercise. I didn't need it as my fingers proved sufficient. Also, fingers and tongue depressors are WAY less expensive than the Therabite!
