What Are Talon Cusps?

A talon cusp is a growth on the inner surface of the tooth (facing the tongue). The name comes from their shape, which is similar to a talon or claw. This rare condition occurs before the calcification stage, most likely because of evagination, which is when a protrusion on a tooth extends the structure’s original position.

Incidence Rates of Talon Cusps

Talon cusps are rare, affecting only 1% to 6% of the population. They mostly appear on permanent teeth and are very rarely found on baby teeth, though it is possible. Most talon cusps are found on an upper tooth, specifically the top central incisors, the maxillary lateral incisors, and the canines.

Causes of Talon Cusps

Doctors and scientists have not found an exact cause of talon cusps. It is likely a combination of environmental and genetic factors that each play a part in the formation of talon cusps.

Effects on Dental Health

A small talon cusp on a tooth may not have any effect on your dental health and you can chew, speak, brush your teeth and other daily functions without any problem. A large talon cusp, however, can worsen problems like gum irritation, cavities, and mouth injuries, and in some instances, they can even cause challenges with eating or speaking.

Treating Talon Cusps

Small talon cusps may not need treatment if they are not a hindrance to your daily life. A talon cusp should be treated if it is causing a dental issue, like frequent cavities, or if it affects your quality of life, like your ability to speak or chew. In these cases, your doctor may recommend a root canal of the talon cusp tooth or other treatments.
