You must have heard the term “missing teeth”. On the contrary, some people have extra tooth which, like missing teeth, can lead to malformations. In fact, when the number of teeth exceeds the standard number, they are considered as abnormal teeth; this is known as hyperdontia or extra teeth. Only one to four percent of the world’s population suffer from this malformation.
Hyperdontia affects only a small portion of the population and the prevalence of this malformation in men is approximately twice that in women. Patients born with cleft lip or palate are at a higher risk for extra teeth. In addition, patients with Ehler-Danlos or Gardner’s syndromes are also at a greater risk for developing hyperdontia. Given the complications of the extra teeth, they are recommended to be extracted as soon as possible to avoid serious complications. The dentist may first physically examine the tooth to determine if surgery is needed.
Replacement of original tooth with extra tooth
Perhaps this question may have also arisen to you that “whether the original tooth can be replaced with the extra tooth to correct the complication at the same time?” It depends on the location of extra tooth. Sometimes a single extra tooth is located between two anterior teeth, which affects the whole face and thus should be extracted. However, sometimes there is an extra tooth at the end, and the extra tooth is able to replace the original one by extracting the permanent tooth. Normally, equal number of teeth should be present in the upper and lower jaws same. The teeth cannot be matched in the case of an extra tooth in one of the jaws. The extra tooth can be orthodontically placed between two molar teeth when a tooth is dropped or pulled out. As a result, extra teeth, like missing teeth, are problematic.
So the important thing is to determine the location of the extra tooth in the mouth and also the number of tooth .Is there any space for the extra tooth in the mouth? If there is, the extra tooth will not be definitely pulled out.
Paying attention to the extra tooth root
The root of extra tooth should be also taken into consideration. Sometimes the extra teeth lack good roots and are tilted, small or deflected at the end. It is very difficult to move extra teeth with deflected roots. The extra tooth root may be actually like a hook at the bottom and cannot be moved. Moreover, the type of oral disease should be considered.
Extra tooth extraction
Sometimes, extra teeth need to be extracted. For example, if the tooth is partially or completely decayed, the orthodontist may decide to pull it out from the mouth. To this end, the tooth is slowly moved back and forth to be separated from the root.
In some cases, the patient may have one or more extra teeth or so-called supernumerary teeth in the jaw. Patients usually have only one extra tooth, but there may be multiple teeth in some cases, known as hyperdontia.
An extra tooth growing in the anterior region of the maxilla is called mesiodens. Teeth crowding can be treated through fixed orthodontics by an orthodontist. For more information on the cost of orthodontics, please contact Dr. Jamilian, orthodontist.
Extra tooth FAQs
1-Is extra tooth hereditary?
Genetic studies show that some children may inherit this disease. However, between one to two percent of healthy children might also experience Hyperdontia.
2-What can we do to prevent Hyperdontia?
Children’s teeth must be examined by an orthodontist after the age of six to prevent any possible serious problems.
3-What problems Hyperdontia can cause?
They populate the mouth and cause irregularity in the permanent teeth, speech problems, chewing problems, deformity in the face, and delay in the growth of the permanent teeth, which can lead to more damage if not treated in time.
4-Why the extra tooth tilts the adjacent teeth?
Hyperdontia prevents the adjacent teeth from growing out which leads to a crowded mouth and irregularity in the permanent teeth.
5-In which jaw Hyperdontia is more common?
Although Hyperdontia can happen in any area on the jaws, its occurrence on the upper jaw is more common.
6-What are the dangers of having Hyperdontia?
The root of the extra tooth can deteriorate the root of permanent teeth after reaching them.
7-What should we do if an extra tooth is growing?
You should visit a dentist because in most cases these teeth must be quickly extracted to prevent any serious problems.
8-How can we know that the delay in the growth of the permanent teeth is because of Hyperdontia?
If the growth of a permanent tooth took more than six months after the fall of the baby tooth, there is a possibility for Hyperdontia. The extra tooth prevents the growth of permanent teeth in the mouth.
