What is hyperdontia?
Hyperdontia is a dental condition where an individual develops extra teeth beyond the typical number. Normally, children are born with 20 primary teeth, which are eventually taken place by 32 permanent teeth as they grow. However, in cases of hypodontia, individuals have additional teeth known as supernumerary teeth.
Primary teeth, also called baby teeth, usually emerge by the time a child is three years old and fall out by the age of 12. These are replaced by permanent teeth, which typically finish erupting by the time a person turns 21. If someone has more than 20 primary teeth or more than 32 permanent teeth, they are diagnosed with hyperdontia.
The exact cause of hypodontia is not fully understood, but research suggests a genetic component may play a role. It is also commonly associated with conditions like cleidocranial dysplasia, Ehlers-Danlos syndrome, Gardner syndrome, or cleft lip and palate. Hyperdontia is relatively rare, affecting about 1–4% of the population in the United States, and most cases involve just one extra tooth.
Managing Hyperdontia
The approach to managing hyperdontia depends on the specific situation and the complications posed by the supernumerary teeth. In several cases, orthodontic treatment can help align the teeth, while in others, extraction might be necessary to prevent crowding or other issues.
For children, it is recommended to have an oral evaluation by the age of seven. Early dental checkups not only monitor overall dental hygiene but also help detect conditions like hyperdontia before they become problematic.
If you or your child might be experiencing hyperdontia, it is important to consult a dental professional. Contact our Arlington office today to book a consultation and get the expert care you need.
