What is Hyperdontia | Symtoms, Diagnosis and Treatments

During your life, you possess two pairs of teeth. Humans have 20 primaries (baby) teeth as a youngster. Those teeth fall off, and 32 wisdom teeth, often known as adult teeth, take their place. Some persons had more than 32 teeth.

Hyperdontia (Extra Teeth)

Three or more additional (supernumerary) teeth affect up to 3.8 percent of persons. An additional tooth might be visible (it has broken through the gums) or impacted (it has not burst through the gums).

Hyperdontia in infants may go unnoticed. Extra baby teeth usually appear normal, appear on time, and are aligned with the remainder of the teeth.

Extra molars can grow in a variety of places in your mouth, including:

  • Mesiodens. All of those are teeth that grow in between your two forward teeth (maxillary incisors). Additional teeth of this type are the most prevalent.
  • Paramolars. And those are the teeth that develop next to the molars.
  • Distomolars. These will develop in the same manner as the remainder of your molars. ‌

The additional tooth can be in any of the following shapes:

  • Conical. It is a tiny tooth with a cone shape. This type that grows behind the primary teeth is this one.
  • Tuberculate. It is indeed a barrel-shaped tooth that usually appears in pairs and comes from the gums only seldom.
  • Supplemental. The above tooth looks like a regular dentition and is typically found there at end of a row.
  • Odontoma. This occurs when dental material has developed in an atypical manner.

Hyperdontia Symptoms

Hyperdontia can be caused by a variety of factors

The specific etiology of Hyperdontia is unknown to experts. You may have several extra teeth if you possess a condition such as:

  • Gardner’s syndrome is a condition in which a person is a hereditary condition that increases your chances of developing malignancies. Gardner syndrome patients, for instance, have a greater risk of developing colorectal cancer at such an early age.
  • Fabry disease is a genetic disorder. The body seems unable to produce an enzyme that breaks down fatty compounds whether you have a rare illness. Serious burning pain in the hands and feet, itchy skin, stomach problems, and an incapability to sweat are all symptoms of this disorder.
  • Dysostosis of the cleidocranial. It is a really rare disorder that affects your bones, especially your head and collarbone, which runs in families.
  • Cleft lip and palate are two different types of clefts. There is a hole in the roof on your mouth or perhaps the top lip. Both of these birth abnormalities occur extremely early in pregnancy. These can cause ear infections, as well as difficulties with eating, hearing, and speaking.

Extra Teeth Causes Issues

Extra teeth are normally painless. However, they may arrive in weird positions and appear strange. These may not burst through the gum line, but they might still cause problems with your other teeth. ‌

Extra teeth can cause a variety of problems, including:

  • Avoid your natural teeth from erupting.
  • These other teeth should be pushed out of place.
  • Even other teeth’s origins will be harmed.
  • causing crowding of your teeth

Cysts may form between your extra teeth. According to a study, 11% of individuals with additional teeth have them. Dental teeth may develop in your nasal cavity in some very uncommon circumstances.

Hyperdontia Diagnosis

It’s simple to notice your extra tooth and diagnose Hyperdontia if they’ve grown in. However, for many individuals, the extra teeth are only identified after a dentistry X-ray and when a predicted tooth fails to emerge. Hyperdontia could also be diagnosed using a CT scan.

Hyperdontia Treatment

The therapy for additional teeth is determined by the type and location of the extra teeth. This even depends on how they affect the teeth around them. Certain Hyperdontia conditions might not require treatment. Alternatively, the dentist will monitor them and, if required, take an X-ray.

Whether you have additional teeth, your dentist may advise you to have them extracted if they:

Prevent a neighboring tooth from erupting or shift it out of the way.

  • Certain types of dental procedures, such as braces, may be hampered.
  • Cysts and injury to the foundations of neighboring teeth can occur as a result of this.
  • Arrive unexpectedly (spontaneous eruption)
  • obstruct the insertion of a bone graft and implant
  • Although your extra tooth is in an uncomfortable position, it prevents you from either brushing or washing properly. Cavities are more likely as a result of this.
  • Make you self-conscious about your appearance

When it comes to minors, experts dispute when the extraction should take place. According to some specialists, the extra tooth should be extracted as soon as possible after diagnosis.

Others advise delaying Hyperdontia surgery till your child is around the age group of 18 and 10. Hence roots of ordinary teeth would be able to form as a result. As a result, when the additional teeth are extracted, the injury to the ordinary teeth is minimized.

Only when your extra teeth are visible, individuals may be able to remove them as easily as a frequent tooth. If they’re hidden behind anything like your gums or a layer of tooth bone, though, an oral surgeon would have to elevate the gums or eliminate the bone deposit first. Your gums will be sewn up or the bones will recover after a tooth is removed.

Even when an additional tooth has merged with the following tooth, other than at the crown or even at the root levels, it may be difficult to remove it.

Standard teeth may not appear for 6 months until 3 years after a child’s additional teeth have been removed.


Hyperdontia has several side effects, including:

  • The gap among teeth is called a diastema.
  • twisted overpopulation
  •  teeth
  • Inflammatory and discomfort
  • Gingivitis, for example, is a type of infection.
  • The emergence of permanent teeth is postponed.
  • everlasting incisors impaction
  • The tooth inside the area has irregular root development.
  • cystic lesions upon that gums and tooth
  • The tooth not falling out promptly

Your dentist should be consulted if a person discovers extra teeth, particularly those which are not in contact with the surrounding teeth.

In general, any soreness or discomfort in the mouth should be addressed by a dentist.

Thus it is critical to have regular dental checkups. During a routine inspection or X-ray, a dentist may notice Hyperdontia.
