Talon cusp is an uncommon dental developmental anomaly that typically appears as an accessory cusp-like structure projecting from the cingulum to the cutting edge in primary or permanent anterior teeth. This article presents 11 cases of talon cusp in seven patients. Three patients had unilateral talon cusps, one of which affected a permanent maxillary central incisor and included an unusual concurrent combination of dental anomalies; the other two affected permanent maxillary lateral incisors. The remaining eight talon cusps were observed bilaterally, with six affecting the permanent maxillary lateral incisors and the other two affecting the permanent maxillary canines.
