Sounds like you've been dislocating your Jaw...I'd get it checked out by a doctor. Not something to play with. They have some newer mouth pieces that are supposed to more shock absorbent. You could try moving your lower jaw left and right hoping to slide it back into joint. The mandible is kind of free floating attached by powerful muscles. I'd also look into wearing head gear.
