Simple Dental Deformity

Extra tooth

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.

Extra tooth should be extracted because they can interfere with the growth of other teeth.

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.
