All you need to know about hyperdontia!

Posted in Dentist

What is hyperdontia? – It is a condition that results in the growth of too many teeth in your mouth. Supernumerary teeth, the extra teeth in the mouth can grow anywhere in the curved areas where these teeth attach to your jaw. These curved areas are sometimes called dental arches.


The standard number of primary teeth or deciduous teeth is 20, whereas, the standard number of secondary or permanent teeth is 32. People with hyperdontia have extra primary or permanent teeth, but extra primary teeth are more common.


What causes hyperdontia?


The accurate cause of hyperdontia is not known yet, but according to experts it is associated with several hereditary conditions, such as:


  • Gardner’s syndrome – it is a genetic disorder that results in skin cysts, colon growths, and skull growths.
  • Fabry disease – this syndrome causes painful hands and feet, inability to sweat, abdominal pain, and a red or blue skin rash.
  • Ehlers-Danlos syndrome – a genetic condition that leads to loose joints that can be easily dislocated, scoliosis, easily bruised skin, and painful joints and muscles.  
  • Cleft palate and lip – these are birth defects that cause an opening in the roof of the mouth or upper lip, ear infections, and trouble while speaking or eating.


Signs & symptoms of hyperdontia


The most important and obvious symptom of hyperdontia is the development of extra teeth behind or close to the primary or permanent teeth. These teeth usually appear during adulthood. Hyperdontia is more common in men as compared to women.


Diagnoses of hyperdontia


If the extra teeth have already grown in then it’s very to diagnose. If they aren’t grown in fully, they’ll still be visible on a routine dental X-ray. Your dentist may also ask you to undergo a CT scan to get a detailed look at your mouth, jaw, and teeth.


Treatment for hyperdontia


It is very important to detect and treat supernumerary teeth as soon as possible because these extra teeth cause both cosmetic and functional problems for the affected individual. Generally, the treatment involves is the removal of the supernumerary teeth when possible.
