sure---i do range of motion primarily--mostly i use a therabite to assure that im not deviating either to the right or to the left. if you dont have a threabite(they are expencive--mine was given tome) you can simply stand in front of the mirror and use your fingers.
open your mouth as wide as you can, put finger on bottom teeth and help yourself open further. hold for 5 seconds and repeat 5 times.
slide to the side as far as you can put your hand on your jaw bone and push---hold for 5 seconds and repeat 5 times. the above exercises should be done 5 times a day.
also you should do some kind of exercise that will strengthen your core like yoga or pilates--avoid anytning that jostles the head
i will go find the thread i made on jaw exercises and see if i cant make it a sticky so that you all can see it and referr to it from time to time.
