Tooth avulsion is a type of dentoalveolar trauma that causes great concern regarding the patient’s prognosis. Proper storage of avulsed teeth is essential for treatment success. This article aims to present a case report describing an avulsed tooth successfully treated, which was replanted late and developed extensive external inflammatory root resorption with a root fracture but remained stable and asymptomatic after five years of follow-up due to appropriate therapy.. A 10-year-old female patient suffered an avulsion of tooth 11 during school play. The avulsed tooth was kept in the mouth, and reimplantation was performed at a clinic about two hours later, with semi-rigid splinting and lip suturing. After six months, the patient showed swelling, pain, and extensive root resorption, initiating endodontic treatment. In conclusion, despite the avulsion and severe root resorption, the reimplantation succeeded, and the treatment proved effective in maintaining the tooth’s physiological and aesthetic functions.
