Dentoalveolar trauma is a severe traumatic injury involving alveolar bone and dental structures. Like any trauma, it can leave irreparable sequelae and even cause tooth loss. The aim of this study is to report on the case of a dentoalveolar trauma in a 10-year-old male patient and the treatment performed with 12-month follow-up. The child had lateral luxation and displacement of teeth 11 and 21 in labial direction after a fall from his own height. The patient was examined at a hospital, received medication and was referred to a dental clinic. At the dental office, the teeth were repositioned, as well as received endodontic treatment and dental reanatomization. Two months after the trauma, root resorption was observed externally, which remained stable for 12 months. It was concluded that post-trauma treatment should be immediate and that follow-up sessions should be done carefully to minimize sequelae and to receive better prognosis.
