Bruxism is the term used to describe the involuntary clenching and grinding of teeth. Often, this occurs during sleep, known as nocturnal bruxism. This condition can cause significant damage to the teeth, gums, facial muscles, and temporomandibular joint. While genetic predisposition plays a role in bruxism, stress often exacerbates the frequency and intensity of teeth grinding. Symptoms such as headaches, facial soreness, jaw pain, and gum recession are common with bruxism.

Treatment typically involves the creation of a protective splint, known as a night guard, to be worn during sleep.
