Bruxism and endodontics: how to manage cracked teeth

Bruxism is a repetitive masticatory muscular activity characterized by the grinding and clenching of teeth and/or thrusting of the mandible. This activity can occur during the day (awake bruxism) or at night (sleep bruxism) and patients can potentially generate mandibular forces of up to 900N. This has been known to crack or break unrestored teeth, indirect restorations and even implant fixtures. This article provides an overview of the endodontic considerations in those who experience bruxism and who have cracked teeth. CPD/Clinical Relevance: Bruxism can affect tooth structural integrity and pulp vitality, and can compromise tooth survival.
