What is hyperdontia?

When a child is born, he or she will have 20 primary teeth and 32 permanent teeth. But sometimes kids are born with additional teeth, and our team at Wermerson Orthodontics calls this oral condition "hyperdontia." Primary teeth are the first set of teeth that erupt in your child's mouth, typically by the time they are 36 months old, and are shed by the time your child reaches the age of 12. Permanent teeth then take the place of the primary teeth and are usually fully-erupted by the time your son or daughter reaches 21 years of age. Anyone who develops more than 20 primary teeth or more than 32 permanent teeth has hyperdontia, and the additional teeth are referred to as supernumerary teeth.

While the cause of hyperdontia is not entirely clear, it is believed that there may be a genetic factor. Oral professionals have found that patients with extra teeth often have syndromes like cleidocranial dysplasia, Ehler-Danlos syndrome, Gardner syndrome, or cleft lip and palate. The prevalence of hyperdontia affects between one and four percent of the population in the United States, and the majority of cases are limited to a single tooth.

So, what is the best way to deal with hyperdontia? It really depends on the case. The treatment plan your doctor suggests varies according to the potential problem posed by the supernumerary teeth, as well as their type. Orthodontic treatment may certainly may help, but extraction can also be a good option. We recommend that children receive an oral evaluation or checkup no later than the age of seven. In addition to hygiene evaluation, this helps ensure your child does not experience hyperdontia problems.
