| Abstract: |
A bite plate is provided to protect a user's teeth from damage due to teeth grinding and/or long term interdigitating pressure, as during cervical traction. The device defines a trench for receiving at least some of the upper teeth of a user and is self fitting to accommodate both narrow and wide dental arches. Once inserted into the mouth the device snugly engages the front teeth and remains positioned, keeping the teeth of the upper and lower jaws from directly engaging and being damaged.
