Talon cusp is a developmental dental anomaly, normally located on the palatal surface of the anterior teeth, that can occur in both primary and permanent dentition. The aim of this article is to relate a clinical case of talon cusp that interfered with both the occlusion and appearance of the patient. During anamnesis, the patient told of difficulty masticating. Clinical examination revealed labial inclination of the maxillary central incisors, featuring an overjet of about 5 mm, with interposition of the lower lip and an Angle Class I occlusal relationship. A treatment plan was devised in which gradual grinding of both talon cusps, the fitting of a removable orthodontic device, and clinical and radiographic follow-up were carried out.
