Bruxism is a parafunctional habit of the masticatory system which involves abnormal teeth grinding and clenching. The disorder is quite common, but with little research on this topic, planning a prosthetic rehabilitation for patients with this condition can be a challenging task. The first part of this literature review provides information about bruxism in detail, namely the epidemiology, etiology, and its treatment. In the second part, the relationship between bruxism and prosthetic treatments is discussed. An emphasis is put on the possible harmful consequences of bruxism on prosthetic restorations and the patient's dentition, and how a dentist can prevent these unwanted outcomes.
