What is Hyperdontia?

What is it?

Hyperdontia is the condition of having supernumerary teeth, or teeth that appear in addition to the regular number of teeth. They can appear in any area of the dental arch and can affect any dental organ.The prevalence of hyperdontia is between 1% and 4% of the population with a male to female ratio of 2:1; the majority of cases are limited to a single tooth. There have been reported cases of over 30 supernumerary teeth in one person, but such large numbers are rare.

Symptoms:

The main symptom of hyperdontia that you will notice is extra teeth that grow directly behind or close to your usual primary or permanent teeth. These teeth usually appear in adults. They’re twice as common in men than they are in women.

Extra teeth are categorized based on their shape or location in the mouth.

Shapes of extra teeth include:

  • Supplemental- The tooth is shaped similarly to the type of tooth that it grows near.
  • Tuberculate- The tooth has a tube or barrel-like shape.
  • Compound OdontomaThe tooth is made up of several small, tooth-like growths near each other.
  • Complex Odontoma- Rather than a single tooth, an area of tooth-like tissue grows in a disordered group.
  • Conical, or peg-shaped- The tooth is wide at the base and narrows out near the top, making it look sharp.

Causes:

Their is no clear cause of hyperdontia.There have been studies that suggest that there may be a genetic factor in hyperdontia consisting of an autosomal dominant trait with low penetrance (only sometimes producing supernumerary teeth in a carrier of the mutated gene). Other possible causes include environmental factors and over activity of the dental lamina during tooth development. The dental lamina is a zone of cells that initiates the formation of the tooth germ, which forms the tooth.

Treatment:

Treatment for hyperdontia can vary from person to person. The most common approach is an extraction. Since hyperdontia commonly occurs around the permanent anterior incisors of the maxillary arch (next to your top front teeth), it can be an orthodontic and a cosmetic concern. It is always best to talk with your dental health professional at Gentle Dental Family Care in Kew Gardens about the proper treatment for you.
