Definition:

Supernumerary teeth, also known as hyperdontia, is a term used to describe extra teeth that develop in addition to the 32 permanent teeth that we are predisposed to have.

The most common supernumerary teeth develop in between the maxillary central incisors, and are known as mesiodens. These teeth look like pegs. Molars that form in the area of the wisdom teeth are also a common type of supernumerary teeth, and are typically referred to as supernumerary wisdom teeth.

Also Known As: Hyperdontia
