Avulsion is a critical dental injury in which a tooth is completely removed from its socket due to trauma, making up 0.5–3% of all dental injuries.
In an avulsion injury, damage occurs to the periodontal ligament, the neurovascular bundle, cementum, alveolar bone and gingiva.
Complex treatment is therefore necessary as multiple components of the tooth are affected.
Moreover, instant action taken at the site of incident will improve overall tooth prognosis.
The teeth most commonly affected are maxillary central incisors, followed by maxillary lateral incisors and then mandibular central incisors.
