Tooth avulsion significantly damages the supporting periodontium and usually results in pulpal necrosis in permanent teeth with completed apical root formation. However, when the root of a permanent avulsed tooth is incompletely developed, the possibility of retaining pulp viability or achieving revascularisation of the pulp can be considered. Treatment factors such as extraoral time, extent of damage to the surrounding bone and soft tissue, and tooth storage media, when replantation is delayed, will influence healing and tooth retention. A case report in the management of a 6-year-old patient following multiple avulsions of teeth with immature apical development is presented.
