Hyperdontia is an oral condition characterized by having an excess number of teeth. The standard number of primary teeth is 20 and the standard number of permanent teeth is 32. The additional teeth are referred to as supernumerary teeth. Supernumerary teeth can occur in any part of the dental arch, but the most common supernumerary teeth are permanent, anterior incisors, in the maxillary (upper) arch. The prevalence of hyperdontia is between 1% and 4% of the population with a male to female ratio of 2:1; the majority of cases are limited to a single tooth.
