An 11-month-old boy with a talon cusp in the maxillary right primary central incisor is reported. The patient came to our hospital with an abnormal tooth morphology. An intraoral examination showed that 8 teeth had emerged into the oral cavity, among which 1 tooth was identified with the cusp-like structure on the palatal side that extended from the cingulum to the incisal edge and appeared to be T-shaped in the occlusal view. The incisal edge of the affected tooth was displaced labially and the cusp-like structure was located in the dental arch. Since there were no signs or symptoms to be treated immediately, we decided to carry out periodical examinations. As the patient aged, the height of the cusp decreased. The horn-like extended pulp space was identified in radiographs taken at the age of 3Y0M and 5Y5M. There have been no other signs or symptoms of the affected tooth, except for labial displacement, during the 4.5-year follow-up period.
