Hyperdontia is the term used by dentists to describe when extra teeth grow inside a patient’s mouth. The jaw is designed to accommodate a certain number of teeth only, so of course having extra teeth taking up space can have negative side effects.
The average adult bite consist of 32 permanent teeth. Children have 20 milk teeth. Milk teeth are also referred to by dentists as primary teeth. These teeth fall out as children grow up, and they are replaced by permanent, lifelong teeth. Most sufferers of Hyperdontia have extra primary teeth, although there are some cases of extra permanent teeth forming too.
How does one recognise ‘extra teeth’?
The extra teeth that grow from Hyperdontia look different to regular teeth – molars, premolars, canines and incisors.
There are several types of extra teeth that are found in the mouth. Supplemental teeth take the shape of the teeth surrounding them, while compound odontomas are several small teeth in a cluster, which are similar to Complex odontoma.
Tuberculate are tube-like shaped teeth, and Conical, or peg-shaped teeth are wide at the base, and sharp at the tip.
The extra teeth are also classified by the location where they appear in the mouth. Mesiodens grow behind the incisors. Distomolars are in line with molars, while Paramolars grow around them.
What are the side effects of Hyperdontia?
There are no ‘symptoms’, except that some people may experience a pressure on the jaw. Most people don’t experience pain.
If the extra teeth are starting to affect your dental hygiene or other teeth, like delaying the emergence of permanent teeth, Healthline suggests removing them as soon as possible. This will help avoid any lasting effects, such as gum disease or crooked teeth.
Most people have Hyperdontia due to an underlying genetic condition.
