What is talon cusps?

Talon cusps are highly unusual dental anomalies where an additional cusp, resembling a talon or pointy projection, emerges from the cingulum or lingual ridge of an anterior tooth. Talon cusps can occur in either primary or permanent teeth and are most commonly found in the maxillary lateral incisors.

Some of the common characteristics of talon cusps include an abnormal appearance, sharpness or pointedness, over-eruption, pulp tissue exposure, and susceptibility to plaque accumulation leading to caries or periodontal disease. In some cases, the talon cusp can also interfere with occlusion, bite, and speech.

The exact causes of talon cusps are not well understood but may be associated with genetic or developmental factors. Treatment for talon cusps varies based on the severity of the anomaly but may include smoothing or reshaping the talon cusp to reduce discomfort and improve oral hygiene. In rare cases, the talon cusp may need to be removed entirely.
