Supernumerary teeth are known as extra teeth that grow in the mouth. This oral condition is also called as hyperdontia. This condition can happen to anyone although those who have cleft lip and Down syndrome have higher risk of hyperdontia. Male are also reported to have more supernumerary teeth than females. Normally, people have twenty baby teeth and thirty-two permanent teeth. If they are affected by hyperdontia, it means they have more teeth than they should. People usually have only one supernumerary tooth. However, there are also some cases in which people have multiple teeth. Is it okay to have supernumerary tooth or does it needs to be removed? Let’s get to know further.
What Causes Supernumerary Teeth
People often do not realize that they have a supernumerary tooth until the complete set of baby teeth grow. Supernumerary teeth can cause several oral problems. First, it prevents the permanent teeth to erupt normally. It even can fuse with permanent teeth. In this condition, the teeth will be prone to decay as the extra teeth can be shaped and placed abnormally. Second, it also causes dental crowding. If this happens, you will find it difficult to eat. Even, the teeth can form cyst that can develop into tumor.
The specific causes for hyperdontia are still unclearly known. According to some researchers, environments and family genetics can be the most two feasible reasons for this dental problem. However the reasons are still debatable among researchers as there is no clear evidence of that. So, how the teeth can suddenly appear? Extra teeth develop during the early stage of teeth development. In this stage, a tooth bud splits, forming two teeth, in which one of them is the unwanted extra tooth.
Because the extra teeth can cause some dental problems in the future, you should do some prevention for example, by the time of six years old, when the set of incisors erupt, see a dentist to have the teeth evaluated. From the examination, the dentist will know whether the child has hyperdontia or not. If they do, dentists will also know whether the teeth can cause further problems in the future. Usually people won’t feel any problems after their permanent teeth begin to grow. If there is no problem happens in the present or in the future, there is no need of supernumerary teeth removal.
However, your dentist may recommend you to have the teeth extracted as they cause problems. Supernumerary teeth are teeth with abnormal structure that often lead to crowding and decay, and problems related to occlusal function that can cause difficulty in chewing. In such condition, surgical treatment is indeed necessary. The extraction is done under local anesthesia. For more severe problem, general anesthesia can be performed. It means that the type of anesthesia depends on the severity of the condition. After the surgery, it is expected that the permanent teeth can grow normally and there won’t be any problems in the future. Of course the orthodontist should make sure that there is enough room for the permanent teeth to grow.
