What is Hyperdontia?

Babies are born with 20 primary teeth and 32 permanent teeth, but sometimes children are born with a few extra teeth. Our team at Wells Family Dentistry calls this oral condition “hyperdontia.” Your child’s primary teeth are the first set of teeth that erupt in their mouth, normally by the age of 36 months and are shed by the time your child is 12-years-old. Permanent teeth will take the place of their primary teeth and are normally completely erupted by time your child is 21-years-old. Those who develop more than 20 primary teeth or more that 32 permanent teeth have hyperdontia. The extra teeth are called supernumerary teeth.

We are not entirely clear what causes hyperdontia, but it is believed there could be a genetic factor. Patients with extra teeth often have other syndromes like cleidocranial dysplasia, Ehler-Danlos syndrome, Gardern syndrome or cleft lift and palate. In the United States, there about one to four percent of the population is affected by hyperdontia and most of these cases are only one additional tooth.

The best way to deal with hyperdontia depends on the case. A treatment plan suggested by Dr. James Wells will vary depend on what the potential problem your supernumerary teeth pose on your other teeth, as well as their type. Orthodontic treatment can help, but extracting the additional teeth is also a good option.

We recommend that children receive an oral evaluation or checkup by Dr. James Wells no later than the age of seven. In addition to hygiene evaluation, this helps ensure your child does not experience hyperdontia problems.

If you suspect you or your child may be suffering from hyperdontia, please give us a call to schedule an appointment at our convenient Morehead City, NC office to be evaluated.
