This paper reviews the nomenclature, prevalence, definition, etiology, association with other dental anomalies, diagnosis and treatment planning of talon cusp in the primary anterior teeth. Most of the reported cases have involved the primary maxillary central incisors. However, talon cusps on the primary maxillary lateral incisors are associated with high percentages of anomalies in the permanent successors. This paper reported three such rare cases and dentists should be aware of such additional anomalies.
