The presence of a talon cusp can cause clinical problems. This article reports the case of a patient presenting a talon cusp affecting the permanent maxillary right central incisor causing clinical problems related to caries, displacement of the tooth, occlusal position and tendency to dental traumatism. The management of this tooth included caries removal and reduction of the cusp. Pulp-capping with calcium hydroxide was required because of the presence of pulp horn extensions in the talon cusp.

Intra-oral radiographs showed coronal dilaceration of the germ of the permanent central incisor and the presence of a calcified tissue mass in the area of the trauma which was identified after surgical removal as the permanent upper left lateral incisor. Immediate treatment and long-term options are discussed.
