Talon cusp is a rare developmental anomaly presenting as a wisp like structure arising from the cervical region of anterior teeth. They are predominantly seen in permanent dentition with a male predilection and are commonly seen associated with incisors and on the lingual/palatal surface. The aetiology appears to be multifactorial with a possible likelihood of genetic and environmental involvement routing to disturbances in tooth development at the morphodifferentiation stage. Over the years, few cases of talon cusp among the family members have been reported which strongly supports the genetic influence. We report rare presentations of talon cusp among two family members involving the facial surface of incisors.
