Hyperdontia is a dental condition in which a patient is diagnosed with having supernumerary teeth or an excess number of teeth. These extra teeth are in addition to the regular number of teeth and they can occur in any part of the dental arch.
Typically, by the age of 36 months, a baby will develop twenty primary teeth. This set of teeth falls off by the time a child reaches the age of twelve. In place of these primary teeth, a permanent set of 32 teeth develop in the mouth. This permanent set of teeth are usually completely developed by the age of twenty one.
However, in some people, the number of primary teeth can be in excess of the standard number of 20 teeth, or in the case of permanent teeth, the number may exceed beyond 32. When this happens, the person is diagnosed with hyperdontia.
Is Hyperdontia a Common Dental Condition?
In most cases, the number of excess teeth is limited to one. Cases where a person is diagnosed with multiple number of teeth is a rare occurrence. The condition is prevalent among one to four percent of the population.
What causes Hyperdontia?
Although the specific reasons for hyperdontia are not known, it is believed the genetics plays a role in the development of this condition. In addition to genetics, other potential factors could include either environmental factors or an overactive dental lamina (cells which contribute towards the formation of tooth germ) which could happen at the time when teeth develop.
What are the Conditions Associated with Hyperdontia?
A number of conditions are associated with hyperdontia. These include the following:
• Cleidocranial dysplasia – condition where the collarbones are underdeveloped or absent.
• Ehler-Danlos syndrome – a disorder affecting the connective tissues (skin, blood vessel walls, joints).
• Gardner syndrome – a condition characterized by the presence of tumors inside and outside the colon.
• Cleft lip and palate – an opening or split in the upper lip or the roof of the mouth.
• Down syndrome: a rare hereditary disorder leading to delay in physical growth and mild to moderate disability in the person’s intellectual capacity.
How is Hyperdontia Treated?
Early detection of hyperdontia is important; the sooner the condition is diagnosed the easier it is for the dental professional to create a treatment plan which aligns well both on a functional level and on a cosmetic level.
The treatment usually involves the removal of the extra teeth if possible. If however, there is a delay in diagnosing the condition, then the development of the surrounding teeth could be impacted or the space for the growth of adjacent teeth could be severely restricted which could impact the direction of the development of the teeth. If this happens then the patient will be gently pushed to consider orthodontic treatment.
A common condition seen with hyperdontia is the formation of tumors and cysts which again makes it critical for the patient to seek treatment quickly.
