Abstract: An apparatus for inhibiting or preventing the clenching action of the human jaw. A lightweight clamping appliance to be worn outside the mouth to inhibit the bite due to the placement of pressure at both sides of the face, beneath the maxilla and above the mandible. A two arm clamp, structurally sized for placement around the outline of the face, with a curved sliding mechanism for altering the length between said arms, and a soft cushioned pad at the end of each clamp arm that can be secured in the desired position. A mechanism for adjusting the applied pressure or tension of the device to individual comfort levels and locking the tension level in place positioned comfortably under the chin area. The elements of the appliance that come into contact with the face during application have cushioned surfaces. An attachable chin cushion provides additional support to the wearer.
