What dental condition is referred to as avulsion?

Avulsion refers specifically to the traumatic loss of a tooth from its socket as a result of injury, such as a fall or sports-related incident. This condition is characterized by a complete separation of a tooth from the alveolar bone, meaning it is not merely a loosening or dislodgment but rather a complete removal. Immediate dental care is crucial in cases of avulsion, as the timely re-implantation of the tooth can often lead to better outcomes for retaining the tooth.

Other conditions listed, such as loss of a tooth due to decay, infection of the gums, or severe tooth abrasion, describe different dental issues. Loss of a tooth due to decay involves progressive destruction of the tooth structure by cavities, while gum infections concern periodontal disease affecting the supporting structures around the teeth. Severe tooth abrasion involves wear of the tooth surface due to mechanical action, not an abrupt loss of a tooth. Hence, the correct identification of avulsion as a specific trauma-related incident underscores its unique nature compared to other dental conditions.
