A 14-year-old female presented with a biocortically impacted maxillary right canine causing a severe root resorption of the adjacent central incisor. Cone-beam computed tomography (CBCT) revealed direct contact between the impacted canine and incisor root, with only one-third of the incisor's root structure intact. Surgical removal of the canine was followed by endodontic microsurgery on the central incisor with minimal apical resection and mineral trioxide aggregate (MTA) for root-end filling. Internal bleaching addressed MTA-induced discoloration, and comprehensive orthodontic and esthetic treatments were completed. Over a 15-year follow-up, the incisor remained functional, asymptomatic, and stable, demonstrating that early diagnosis and conservative multidisciplinary management can preserve compromised teeth, maintain alveolar bone, and support successful orthodontic treatment.
