Bruxism is generally defined as the grinding, clenching, or gnashing of the teeth and can occur when awake as well as during sleep. Bruxing when awake, along with other oral habits such as jaw or mouth posturing, cheek biting, and nail biting, often occur without cognitive awareness, especially during periods of concentration, or stressful situations. Once the activity is brought to the attention of the individual it often can be stopped or modified. Bruxism during sleep is distinct from bruxism when awake and occurs in relationship to arousals. Furthermore, it is beyond volitional control. It is also likely that the etiology differs between diurnal and sleep bruxism (1). Whether bruxism occurs during the day when awake or at night during sleep, the occasional outcomes of tooth wear and jaw pain are familiar to most dentists.
