How can a mouth guard help with headaches?

Dawn Marcus
Neurology
Jaw muscles, like other muscles in the head and neck, are naturally in balance. When they get out of balance, muscle tightness can occur. Tight and tender jaw muscles can lower headache threshold. Helping these muscles relax using relaxation techniques and mouth guards or mouth splints can help reduce headache frequency and severity. The Nociceptive Trigeminal Inhibition (NTI) mouth splint has been approved by the Food and Drug Administration (FDA) for the prevention of migraine. This acrylic mini-splint fits over the front teeth to reduce jaw clenching. In one study, migraine sufferers who also had tenderness of the jaw muscles wore this splint at night and during times of stress. After 2 months, their headache frequency was reduced by two-thirds.
