Dental avulsion

Medical condition

Dental avulsion is the complete displacement of a tooth from its socket in alveolar bone owing to trauma, such as can be caused by a fall, road traffic accident, assault, sports, or occupational injury. Typically, a tooth is held in place by the periodontal ligament, which becomes torn when the tooth is knocked out. Avulsions of primary teeth are more common in young children as they learn to move independently (walk and run) and also from child abuse.
