What is Hyperdontia?

Most children are born with 20 primary teeth and 32 permanent teeth. Some children are born with more than this amount, and we refer to this as hyperdontia. Primary teeth are the first set of teeth that develop in your child’s mouth. Permanent teeth take the place of primary teeth and by the time your child is 21, he or she should have 32 permanent teeth.  Anyone who develops more than 32 permanent teeth has hyperdontia. These extra teeth are known as supernumerary teeth. 

The causes of hyperdontia are not entirely figured out, but research suggests there may be a genetic factor involved. Hyperdontia is affects between one and four percent of the U.S. population. The majority of those with hyperdontia have only one extra tooth.

Hyperdontia can be treated by orthodontic treatments, but treatments vary on a case by case basis. Orthodontic treatment may definitely help, but tooth extraction is also a great way to take care of the issue.  We recommend that children receive an oral hygiene evaluation no later than age seven. This is a great way to see if your child has hyperdontia.
