Begin sitting upright. Open your mouth, and hold your chin with one hand so your thumb is on one side and your fingers are on the other side of your lower jaw. As you pull down with your hand, try to close your jaw. Once the jaw is closed, hold the bite for 3 seconds, then relax and repeat. Make sure you give a consistent amount of resistance with your hand throughout the exercise. Do not clench too hard, as that may exacerbate the condition.
