Talon cusp is a rate dental anomaly manifested as an accessory cusplike structure on the tooth crown. This article reports four cases of taln cusp that caused clinical problems related to appearance, occlusal interference, tooth displacement, caries, and tongue irritation. The cases presented were associated with other dental abnormalities, suggesting per se that genetic inheritance may be the causative factor. Clinical and radiographic characteristics of this developmental anomaly and modes of treatment are described.
