Hyperdontia refers to a condition where a person develops more than the normal amount of teeth, which are twenty primary (baby) teeth and thirty-two permanent (adult) teeth. Usually, primary teeth start to erupt (grow) around six months and have all fall out by twelve years. These primary teeth are then usually replaced by the permanent teeth. However, hyperdontia is a disorder which results in extra teeth (supernumerary teeth) which can occur in any part of the dental arch. Most often, supernumerary teeth are permanent teeth incisors in the maxillary (upper) arch or the mandibular (lower) arch, or they may also be present in the premolar or molar region (either erupted or impacted).
This condition is quite rare and usually only results in one extra tooth. However multiple supernumerary teeth are possible too. This disorder usually occurs in combination with other disorders or syndromes, such as a cleft palate, Gardner’s Syndrome, or cleidocranial dysplasia. Hyperdontia can cause numerous problems, such as teeth blockage, crowding or displacement.
Although the cause of hyperdontia is not clear, there are treatment options available that you should discuss with your dentist, orthodontist or oral surgeon. If you or a loved one suffers from hyperdontia, you can choose to visit The Aga Khan University Hospital to tend your dental requirements.
