Bruxism is defined as clenching or grinding of the teeth and is a common parasomnia. It occurs in children and adults. It is more common in smokers. Patients usually complain of soreness in the teeth, jaw or temperomandibular joint as well as headache or neck muscle pain. It is associated with stress and certain medications (Levodopa, SSRI antidepressants). A mouth guard could be employed to prevent tooth damage. Other medications use to treat it include benzodiazepines, muscle relaxers and Botulinum toxin. Psychotherapy, relaxation therapy and biofeedback as well as hypnosis have been tried. Unfortunately, no treatment has been demonstrated to be completely effective.

A true cure is often difficult. There are many treatments available for bruxism, depending on the cause. Some options include dental appliances such as mouth guards, stress management, behavior therapy, biofeedback therapy and some medications, such as muscle relaxants.
