To massage the masseter muscles on each side of your
jaw, place your thumb inside your
mouth and squeeze the thick muscle
in your cheek (toward the back of your mouth) with your fingers. To get at the harder-to-reach jaw muscles inside your mouth, use your index finger to probe for tender areas behind the teeth, and use the finger to massage these spots.
Other home-care therapies, such as moist heat or cold packs on the face, vitamin supplements, or biofeedback are useful for some people.
