I had a root canal a week ago, my face swelled up and got bruised, I now have trismus. When I called the dentist, he said it would get better and that the muscles were reacting to the injuction. I am having trouble opening my mouth more than 2 to 3 fingers width. I have pain in my jaw and face. I am worried about it. From what I can find, use warm compresses, use warm salt water and do passive exercises on the jaw.This is not wat i expected.
I am SO sorry you are having this. Trismus can last a month or more, but whether that is all of your problem, I don't know.
I hope whatever it is will resolve itself for you shortly.
Best to you,
Gellia
