Anyone ever experienced trismus after having dental work done? I had a rear molar worked on 2 weeks ago, and now I can't open my jaw enough to place anything larger that my pincky finger into it. Went to the oral surgeon yesterday, he told me I had trismus, caused by a spasm in my muscle of the jaw due to the needle from the novacain. His suggestion to increase how far my mouth will open, start with 7 tongue depressors, insert between my teeth, and add a new one everyday until I can get 27 in there. Hurts like heck, but willing to give it a try. Haven't been able to eat anything other that pasta & ice cream ( not good for my figure) for a weeks now. Just curious if anyone else has ever experienced this, used this form of treatment and did it work and how long did it take.
