Jason PY - 2021 T2 - The Atlas of Emergency Medicine, 5e AB - Avulsion is the total displacement of a tooth from its socket. There is usually a history of trauma; however, infectious etiologies may result in complete disruption of the periodontal ligament from the affected tooth. Various degrees of bleeding from the socket and surrounding gingiva may be noted, and there may be underlying alveolar fracture depending on the mechanism of injury. Prompt inquiry into the location of any unaccountable tooth is indicated. Radiographic evaluation to rule out aspiration, soft tissue entrapment, impaction, or dentoalveolar fracture is required when teeth are missing.
