Hyperdontia: What Causes It and How Is It Treated?

Dr. Degel Oct 24, 2016

Hyperdontia is a condition in which a person has supernumerary teeth, the clinical term for extra teeth that can grow anywhere in the mouth. The condition can occur in anyone regardless of his or her age, gender, or ethnicity; however, it is most common among:

  • People with Ehler-Danlos syndrome or Gardner syndrome
  • Children born with Down syndrome or cleft lip
  • The Chinese and South American population
  • Males

Although there have been extreme cases of hyperdontia involving 20 or more supernumerary teeth and teeth growing outside of the mouth, most cases are mild and involve one or two extra teeth. Indeed, most people who have supernumerary teeth are unaware of this fact until the teeth have been identified during an oral exam at Astoria Dental Group. It is then that Dr. Clifford Degel or Dr. Carmen Every-Degel explains hyperdontia causes and treatment at our Queens, NY dental practice, helping patients to understand that their extra teeth can be effectively treated and their oral health can be made optimal.

As with any dental condition, hyperdontia can only be definitively diagnosed with a thorough oral exam. To schedule yours, please contact Astoria Dental Group today.

What Are the Causes of Hyperdontia?

A person should generally have no more than 20 primary (“baby”) teeth and 32 primary (“adult”) teeth. Any teeth in excess of these amounts are considered supernumerary. Supernumerary teeth usually appear with primary teeth. In many cases, people with hyperdontia develop only one extra tooth, and often that tooth does not erupt. This is why many people who have hyperdontia are unaware that they are affected by the condition.

The causes of the condition are currently unknown. Many dental experts believe, however, that there is at least a genetic component to hyperdontia. It is also highly uncommon for hyperdontia not to be accompanied by some sort of syndrome.

What Are the Treatments for Hyperdontia?

If it is determined that you have supernumerary teeth and that they are not causing any oral health problems whatsoever, then our dentists may recommend doing nothing whatsoever. Supernumerary teeth can and often do either cause oral health problems or put patients at risk for oral health problems. For example, the extra teeth can:

  • Cause dental crowding or other forms of malocclusion
  • Become impacted
  • Prevent normal primary teeth from erupting properly
  • Fuse with normal primary teeth
  • Increase the risk of periodontal disease, cavities, and infections
  • Cause tumors or cysts to form

In some cases, orthodontic treatment may be sufficient to correcting the oral health problems created by hyperdontia; however, in most cases, our dentists will likely recommend surgical extraction of the supernumerary tooth or teeth.
