Hyperdontia

hyperdontiaExtra teeth growing anywhere in a person’s mouth is called supernumerary teeth and is a specific condition called hyperdontia. The extra teeth can grow anywhere in a person’s mouth and research cannot pin down a specific reason. Family genetics and environmental causes are named, as two main culprits in the cause of hyperdontia. Which elements in the environment is something that has not been established yet. Children with Down syndrome, cleft lip, and Gardner’s syndrome amongst others are often sufferers of hyperdontia.

Supernumerary teeth are seldom appearing with deciduous teeth and more common in permanent teeth. The amount of supernumerary teeth varies, but it is very common to find only one extra tooth, instead of multiple teeth. It is possible therefor that people do not realize that they have hyperdontia after they had a normal set of baby teeth. Many people have an extra set of teeth, which will never emerge, but it is detectable on x-rays.

What is Hyperdontia?

Growing 20 baby teeth are normal and when replaced with permanent teeth a person should have 32 teeth. If you suspect that your family has a genetic possibility for supernumerary appearance, it is safe to take a young child at around six years old to a dentist for x-rays. This will eliminate expensive orthodontic bills, as it is possible to correct the misalignment, which may occur at a later stage if hyperdontia shows up in the x-rays.

Supernumerary teeth are classified in several groups and this is based on location and morphology. The classification according to location is divided into two groups, one as frontal, and the other, back supernumerary teeth. Four classifications in Hyperdontia according to morphology, called Odontoma, supplemental, tuberculate and conical supernumerary teeth. Odontoma on the other hand is further divided into two group classifications. They are compound composite Odontoma and complex composite Odontoma.

Odontoma supernumerary teeth found in a mouth resemble normal teeth structures or it is completely disorganized teeth. Tuberculate teeth have two and sometimes more tubercles and rarely occur, whereas the conical type tooth is peg shaped and often found in the front of the mouth. Supplemental type teeth are the occurrence of normal teeth duplication and appear in the molar, premolar, and lateral incisor regions.

Types of Hyperdontia:

supernumerary hyperdontiaIndividuals suffering from hyperdontia encounter several problems. The extra teeth usually displace the normal adjacent teeth and removal of the extra teeth is necessary to align the normal teeth. Extra teeth or even one extra tooth can cause a hindrance where the normal tooth erupts from the gum. In order for the normal tooth to appear from the gum, the extra tooth needs to be removed first.

Crowding of teeth in an individual’s mouth is a serious problem in hyperdontia, making it extremely difficult to eat normally, and these teeth needs to be extracted. Cyst or tumor formation is another bad side effect in hyperdontia and depending on your dentist in some instances, it is imperative to remove those extra teeth. Supernumerary teeth despite being problematic in some instances can also be present without causing any problems or discomfort.
