The 3 Rare Teeth Problems You Are Probably Unaware Of

Posted on 3/22/2021 by Moyer Office
The 3 Rare Teeth Problems You Are Probably Unaware OfDental problems like tooth decay, cavities, plaque, and tartar are quite common and often heard of. But there are some rare teeth problems in children and adults that you are probably unaware of.

The diagnosis of these dental problems during their early stages is not easy. It is only during the regular, bi-annual dental check-ups that the dentist will be able to diagnose one of these dental problems in your child after a thorough dental examination.

The 3 rare teeth problems that you are probably unaware of are as follows:

Talon Cusps

This rare dental condition is said to affect between 1% to 6% of the world's population. As the name suggests, patients who are affected by the talon cusps condition have a claw-like growth at the back of their teeth. This extra cusp of teeth usually forms at the back of the canines and incisors and can cause problems like:

•  Teeth crowding
•  malocclusion
•  bad bite
•  bad smile
•  sores in the cheeks, gums, and tongue
•  plaque formation
•  inconvenience while brushing teeth

The real cause of talon cusps remains to be unknown, but it is said to be a genetic disorder that runs in families. More men are affected by talon cusps as compared to women. If the formation of talon cusps is diagnosed in the early stages, the sharp edges can be filed to form a smooth surface, but if this extra tooth becomes infected, then your dentist will suggest the best treatment for it. In most cases, the talon cusp is extracted to prevent overcrowding, plaque formation, and tooth decay.


Hyperdontia or supernumerary teeth is a condition in which extra teeth either remain in the gums or grow out of it. In most cases, children only have one extra tooth growing out of their gums. But the growth of this extra tooth disturbs the alignment of the teeth and results in overcrowding. It can even push the original tooth backward or towards the front, giving the appearance of crooked teeth.

Just like talon cusps, the exact cause of hyperdontia is unknown, but according to the experts, hereditary conditions like Gardner's syndrome can lead to the growth of extra teeth in a person's mouth.

In most cases, hyperdontia is left untreated especially because the removal of these extra teeth could displace or damage permanent teeth. But if the patient faces discomfort while biting or chewing or wants to remove the extra tooth for cosmetic reasons, then the dentist will suggest tooth extraction to pull out the extra tooth.


Hypodontia is also known as anodontia. It is a very rare genetic condition in which a person's permanent teeth never grow. After the child loses his/her milk teeth, the permanent teeth don't grow to take their place. But according to the National Organization of rare Disorders (NORD), it is rare that patients with anodontia have all their teeth missing. Patients with anodontia have between 1 to 5 missing teeth.

It is said that several genes are responsible for causing anodontia in a person, but the risk of this rare dental problem increases if the person is also diagnosed with ectodermal dysplasia. Ectodermal dysplasia is a genetic disorder in which the growth and development of teeth, nails, hair, and sweat glands is affected.
Anodontia can be treated by using removable dentures.
