What is Hyperdontia?

Have you ever heard of people having “extra” teeth? The medical term for this condition is called Hyperdontia. You may also hear us call the extra teeth “supernumerary teeth”. Normally a child is born with 20 primary teeth and 32 adult teeth. Primary teeth are the first set of teeth that erupt and typically erupt between birth and age of 36 months. Permanent teeth then take the place of the primary teeth and are usually fully-erupted 21 years of age.

The cause of hyperdontia is not clear however, it is thought to be genetics. Hyperdontia affects between 1 and 4 percent of the population in the US, most 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 Dr. Fleming suggests will vary according to the potential problem posed by the supernumerary teeth, as well as their type. Orthodontic treatment certainly may help, but extraction of the extra tooth can also be a good option. We recommend a child receive an oral evaluation no later than the age of 7. This will help us to determine if your child has hyperdontia and the proper course of action.

If you suspect you or your child may be suffering from hyperdontia, please give Fleming Orthodontics a call to schedule a complimentary appointment.
