I have developed trismus as well. My RO gave me a large handfull of tongue depressors and said that they will do what the expensive devices will do. My dentist said pretty much the same thing. My dentist also gave me a brochure on TMJ with exercises that you can do at home for it. (Possibly the same kind of exercises that you would receive at PT, but I'm not sure) I've been using the tongue depressors and they seem to work ok, but I still can't open my mouth as wide as I used to be able to. I guess I'll just keep working on it. Hope this helps.

Nine years out. New normal with limitations, but surviving and living life to the fullest.
