X-ray of a human skull with #Hyperdontia
Hyperdontia is an oral condition characterised by having an excess number of #teeth. The standard number of primary teeth is 20 and the standard number of permanent teeth is 32. A person who develops more than 20 primary teeth or more than 32 permanent teeth has hyperdontia. The additional teeth are referred to as supernumerary teeth.
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. There have been reported cases of over 30 supernumerary teeth in one person, but such large numbers are rare.
