A talon cusp is an uncommon anomaly in the primary dentition (10%) as compared to the permanent dentition (90%). Since it was first reported in 1977, there have been only 37 documented cases in normal children. Most cases involve the primary maxillary central incisors, and very few cases involve primary maxillary lateral incisors. Here, we present a rare case report of a 10-year-old child who had talon cusp on deciduous maxillary right lateral incisor associated with supernumerary permanent successor. The tooth with talon cusp was extracted and the underlying supernumerary permanent successor erupted in the oral cavity. The patient was kept on recall to conservatively manage the supernumerary tooth.
