Traumatic dental injuries (TDIs) occur frequently in children and young adults, comprising 5% of all injuries. Twenty‐five percent of all school children experience dental trauma and 33% of adults have experienced trauma to the permanent dentition, with the majority of the injuries occurring before age 19. Dental avulsion is one of the most common among these dental injuries. When the tooth is knocked out, the blood supply to the pulp is interrupted and the periodontal ligament cells are exposed to injuries caused by the external environment. In recent years, research findings have shown the possibility of complete healing under favorable conditions: replanting the tooth according to the criteria required by the guideline such as the extra oral time which should be very short, the time of pulp removal after replantation, and the appropriate storage medium. This set of criteria may lead to a slower progression of the phenomenon of resorption with a better prognosis over time; however, there is a high risk of complications such as external root resorption in case of delayed replantation. This case report presents a case of replantation of avulsed maxillary central incisor and lateral incisor after an extended extra-alveolar period of 1.5 hours.
