What is the term for extra teeth beyond the normal count?

The term for extra teeth beyond the normal count is hyperdontia. This condition refers to the presence of one or more supernumerary teeth, which are teeth that develop in addition to the normal dental formula. The typical human adult has 32 teeth, and when an individual has more than this, it is classified as hyperdontia.

This condition can manifest in various forms, such as additional incisors, canines, or molars, and is usually diagnosed through dental examinations or imaging. Recognizing hyperdontia is important as it may lead to complications, such as crowding, misalignment of the teeth, and other dental issues that may require intervention.

The other terms refer to different dental conditions. Hypodontia describes the absence of one or more teeth in the dental arch, oligodontia indicates the absence of six or more teeth, and anodontia refers to the complete absence of all teeth. Each of these conditions represents a deficit in tooth count, contrasting with hyperdontia, which involves an excess.
