Bruxism or teeth grinding, defined as the habitual nonfunctional and forceful contact between occlusal surfaces, can occur while awake or asleep. The etiology is multifactorial and has been reported to include central factors (eg, emotional stress, parasomnias, traumatic brain injury, neurologic disabilities) and morphologic factors (eg, malocclusion, muscle recruitment). The occlusal wear that may result from bruxism is important to differentiate from other forms of occlusal loss of enamel (eg, erosion caused by diet or gastroesophageal reflux). Reported complications of bruxism include dental attrition, headaches, temporomandibular dysfunction, and soreness of the masticatory muscles. Evidence indicates that juvenile bruxism is self-limiting and does not persist in adults. The spectrum of bruxism management ranges from patient/parent education, occlusal splints, and psychological techniques to medications.
