Bruxism refers to clenching and grinding of the teeth. Often, teeth clenching and grinding occurs at night while you sleep, and is referred to as nocturnal bruxism. Bruxism can be a very damaging condition, affecting the teeth, gums, facial muscles, and temporomandibular joint. Most frequently, patients with this issue have a genetic predisposition for bruxism, but stress often contributes to the frequency and intensity of teeth grinding. Headaches, facial soreness, jaw pain, and gum recession commonly accompany bruxism.

The treatment for bruxism usually involves the fabrication of a protective splint (night guard) to be worn while sleeping.
