Does any one else have this problem? I have always gritted my teeth, and use a night gaurd. I have had a problem for a few years with my facial muscles tightening, and causing extreme pain and headaches at times. To releive the pressure I would open my mouth and sort of pop the joint. The last three days it has been a different kind of pain.On the right side it hurts in general , but chewing and talking is really painful. What most concerns me is when I open my mouth and look in the morror I can actully see where the joint in sticking out like a knob on the side it also clicks when I open my mouth .I have not been injured. Why would this happen. Should I go to a dentist or doctor of some sort?Does anyone else have this?
