It could be TMJ, heat helps and you need to pop up your jaw back into place. To do so, open your mouth and put your thumb on the left side of your jaw and point your middle finger towards your right ear. Then push right and close your mouth at the same time, you should hear a popping noise. Do that once a week. It should help.
