Tooth, Supernumerary

Definition:

Objective: Extra tooth or teeth

Comments:

The most frequent supernumerary tooth is a mesiodens, which occurs between the two maxillary central incisors. Often it fails to erupt, but creates a large anterior diastema, and would not be detected on physical examination (requires X-ray evaluation). This designation excludes coexistence of primary and permanent dentition due to delayed loss of the former.
