What is Hyperdontia?
Hyperdontia is a condition in which too many teeth grow in your mouth. All these extra teeth are also known as supernumerary teeth. They can grow anywhere in the curved regions where teeth attach to a jaw. This region is popularly referred to as the dental arches.
The 20 teeth which grow in when you are a kid are called primary, or deciduous teeth. The 32 adult teeth that replace them as you grow are known as permanent teeth. You can have additional permanent or primary teeth with hyperdontia, but additional primary teeth are somewhat more common.
The prevalence of hyperdontia is between 1% and 4 per cent of the people using a male to female ratio of 2:1; the vast majority of cases are restricted to one tooth. There are reported cases of over 30 supernumerary teeth per individual, but such big numbers are not very common.
Symptoms of Hyperdontia or Supernumerary Teeth.
The most common symptom of hyperdontia is the increase of extra teeth straight behind or near a customary primary or permanent teeth. These teeth normally appear in adults. They are double as common in men than they’re in women.
Extra teeth are categorized according to their shape or place in the mouth.
Shapes of extra teeth or supernumerary teeth comprise:
|Supplemental||The shape of these extra teeth is similar to the kind of tooth it grows nearby.|
|Tuberculate||This extra tooth has a tube or barrel-like shape.|
|Compound odontoma||This particular tooth is made up of many small, tooth-like growths near each other.|
|Complex odontoma||This particular tooth is made up of many small, tooth-like growths near each other.|
|Conical, or peg-shaped||The tooth is broad at the base and contracts out close to the top, which makes it seem sharp.|
Locations of extra teeth comprise:
|Paramolar||An excess tooth grows in the back of the mouth, alongside one of your molars.|
|Distomolar||An excess tooth grows in line with your other molars, instead of around them.|
|Mesiodens||An excess tooth grows behind or around your incisors, the four horizontal teeth in the front of the mouth used for biting. This really is the most usual kind of extra tooth in people with hyperdontia.|
Hyperdontia usually is not painful. But, on occasion, the extra teeth may place pressure in your gums and jaw, which makes them painful and swollen. Overcrowding or Malocclusion brought on by hyperdontia may make your teeth seem twisted.
What causes Hyperdontia?
The reason behind hyperdontia isn’t entirely clear. It’s believed that there might be a hereditary factor in hyperdontia composed of an autosomal dominant trait with a low penetrance (only sometimes producing supernumerary teeth in a carrier of the mutated gene). Other potential causes are environmental variables and overactivity of the dental lamina during tooth development. The dental lamina is particularly a zone of cells that initiates the creation of tooth germ, which creates the tooth. Some more causes of extra teeth include:-
Gardner’s syndrome. A rare hereditary illness that leads to skin ailments, colon growths, and skull growths.
Ehlers-Danlos syndrome.An inherited illness which leads to loose joints which readily dislocate, easily bruised skin, scoliosis, and painful joints and muscles.
Fabry disease. This syndrome triggers an inability to sweat, painful feet and hands, a blue or red skin rash, and stomach pain.
Cleft palate and lip. All these birth defects cause an opening in the roof of their mouth or upper lip, difficulty talking or eating, and ear diseases.
Cleidocranial dysplasia. This condition causes unnatural development of the skull and collarbone.
Types of extra teeth.
Dentists classify supernumerary teeth with their form and location.
A supernumerary tooth could be”supplemental” and have an identical form and body as a tooth. Or, it can be”rudimentary,” in that case it’s in an abnormal shape and is often much smaller than the surrounding teeth.
A dentist can even categorize a rudimentary tooth as “tuberculate” if it’s in a tube- or barrel-like form. A rudimentary tooth may rather be”conical,” using a wide base and narrow top. In other scenarios, a dentist might find an extra tooth to be an odontoma, a benign tumour composed of dental tissue which has shaped irregularly.
An odontoma could be compound, composed of little tooth-like structures, or complicated, incorporating a mass of tissue that doesn’t resemble a tooth.
Supernumerary teeth may form throughout the mouth. The dentist can even categorize them by their location, as follows:
- Mesiodens. This is an extra tooth growing between the two incisors — the front teeth of the upper jaw.
- Paramolar. This is an added tooth growing next to one of those molars, out of line with all the other teeth.
- Distomolar. This pertains to an extra tooth growing in line behind the molars — the big, flat teeth in the rear of your mouth.
Most additional teeth are mesiodens.
How is hyperdontia recognized?
Hyperdontia is simple to diagnose when the extra teeth have grown in. Should they have not completely grown in, they will still appear on a regular dental X-ray. Your dentist can also use a CT scan to acquire a more thorough look in your mouth, jaw, and teeth.
Dustin, from stranger things, also suffers from supernumerary teeth, Cleidocranial Dysplasia to be exact.
How To Treat My Extra Teeth?
While there are some cases of hyperdontia that do not require treatment, others need eliminating the extra teeth. Your dentist may also probably suggest removing the extra teeth for those who:
- Feel pain or distress because of overcrowding.
- Have an inherent genetic condition causing the excess teeth to look.
- Can not chew properly or your teeth cut on your mouth when you chew.
- Have a tough time cleaning your teeth flossing due to the extra teeth, which might result in decay or gum disease. This may further lead to needing dental fillings and Root Canals.
- Feel self-conscious or uncomfortable concerning how your extra teeth look.
If the extra teeth have started to affect your dental hygiene or other teeth like delaying the eruption of your permanent teeth, it is ideal to eliminate them whenever possible. This can help prevent any lasting effects, such as gum disease or jagged teeth.
Living with Hyperdontia
A lot of people with hyperdontia or supernumerary teeth do not require any therapy or treatment. Others might have to have any or all their extra teeth eliminated to prevent any other issues. Be certain that you inform your physician about any feelings of pain, swelling, irritation, stiffness, or weakness in your mouth when you’ve hyperdontia.
