Hyperdontia - when there are many teeth in the mouth

Polyodontia (hyperodontia, hyperdentia) is the appearance of supernumerary teeth. Normally, an adult has 28-32 teeth (including wisdom teeth); with polyodontia, an indefinite number of extra teeth appear. About 2% of the world's population suffers from the pathology.

There are no methods to prevent the development of polyodontia, but it is possible to reduce the number of complications caused by the disease. Therefore, it is necessary to be attentive to your health and undergo a preventive examination with a dentist twice a year. If you suspect that an extra tooth has appeared in your mouth, you should immediately consult a doctor. Particular responsibility lies with parents, since children are not able to independently monitor the health of their teeth.

Concept and signs of supernumerary teeth

Hyperdentia (hyperdentia from hyper and lat. dens, dentis tooth) is an anomaly in the number of teeth.
Up to a certain age, children should ideally have twenty milk teeth, which are gradually replaced by permanent ones, and there are 32 of them. With hyperdontia, these numbers shift by one or more positions in a larger direction, since in this case there are one or several more tooth buds than normal.

Supernumerary teeth, as a rule, erupt after the main teeth, but there are exceptions when the supernumerary has erupted and taken the place where a normal tooth should be. As a result, teeth shift and bite changes. Only in rare cases does hyperdontia make itself felt during the period of milk eruption. Most often, this anomaly occurs among men, which accounts for about 65% of the total number of such cases.

In 15% of cases of this anomalous phenomenon, more than two supernumerary teeth erupt on the gum or palate. The most common phenomenon among hyperdontic anomalies is the eruption of supernumerary teeth in the area of the lateral incisors on the upper jaw, and less often on the lower jaw. Such teeth may differ from normal ones in shape, structure, color, which indicates their abnormal origin.

What treatment is required

Treatment of hyperdontia can be carried out in several directions. The choice of a specific method or their combination depends on the patient’s age and the clinical picture as a whole. For children, therapy usually involves eliminating symptoms and correcting pathology. Severe cases in adults may require surgery.

How to relieve teething symptoms

If the child is still very small, under the age of 3 years, he is prescribed antipyretic drugs to normalize the condition and relieve acute symptoms of teething. For very young infants, products in the form of suppositories or suspensions are recommended. To relieve pain, medications with analgesic and anti-inflammatory effects, such as Kalgel, Soloxeril or Dentinox, can also be prescribed. Until a certain age, serious interventions are contraindicated, so myogymnastics methods are usually used as therapy.

Antipyretics may be used to relieve teething symptoms.

Orthodontic correction

Correction using orthodontic removable and fixed structures begins only after removal. Timely treatment stimulates proper growth of the jaw system, corrects existing defects and provides favorable conditions for the eruption of permanent incisors, canines and molars.

Braces are installed only after removing unnecessary elements

For children with primary occlusion, removable soft-action devices are prescribed, for example, elastopositioners or orthodontic plates. At the age of 12-14 years, permanent braces are installed, which can be supplemented with elements that increase the pressure of the system.

When is removal prescribed?

The removal operation is performed when supernumerary units have a negative impact on the formation of the jaw system. Be sure to remove dystopic and impacted elements, especially those with pronounced instability. However, extraction can be avoided if the extra teeth do not affect aesthetics or functionality in any way.

Hyperdontia in an adult

In adults, hyperdontia is much more common than in children. Additional teeth are mainly located in the palate or on the gums, which is unnatural and contrary to the norm. The eruption of an “extra” tooth can cause the following symptoms:

Impaired diction. The person begins to burr and vaguely pronounce some sounds and sound combinations.
A feeling of discomfort caused by the abnormal position of supernumerary teeth. Such teeth provoke curvature of the dentition.
Malocclusion. This problem entails a number of dental diseases, such as pathological tooth wear, impaired diction and others.
Damage to the oral mucosa with subsequent inflammation;
Impaired chewing function, which leads to gastrointestinal problems.

This type of anomaly often causes nervous breakdowns and mental disorders. Due to the displacement of the dentition, healthy teeth lose their strength and begin to loosen under the pressure of the growing supernumerary rudiment. The jawbone swells, which leads to pain. Constant aching pain leads to irritability, apathy and deterioration in general well-being.

Why does retention occur?

Most often, wisdom teeth cannot fully erupt. This is due to the peculiarities of their location. In the process of evolution, eights have lost their meaning. Some people don't have them at all. In others, they often “sit” under the gum and contribute to the displacement of neighboring units, which causes the bite to change.

Retention is caused by:

heredity;
premature removal of baby teeth, which leaves little room for constant sweat;
excessively thick gum walls (very rare);
malocclusion, severe crowding.

Hyperdontia in children

Sometimes the eruption of extra abnormal teeth in children is almost asymptomatic. The only sign of polyodontia is the number of teeth erupted, which exceeds a certain norm for a particular age. Most often, this anomaly is accompanied by a number of unpleasant symptoms, which should cause concern among parents and become a reason to consult a dentist.

Signs of polyodontia in children:

a rapid increase in temperature, which is difficult to bring down and lasts from one to several days;
a strong aching or throbbing pain is felt at the site where the irregular tooth erupts;
there is a feeling of discomfort when talking, eating, drinking;
a slight swelling of the cheek and even the wing of the nose is noticeable on the side where the extra element erupts;
due to excessive salivation as a reaction to an irritating factor, a wet cough and difficulty breathing may occur;
gastrointestinal disorder as another reaction of the body to the inflammatory process and high temperature.

The symptoms of the eruption of supernumerary teeth in children are similar to those observed when the first milk teeth appear, only in this case the situation is a little complicated by the fact that the germination of an extra tooth is not something normal and inherent in nature. This makes it more difficult for the child to tolerate this phenomenon than the eruption of healthy baby teeth.

Symptom relief

Most often, in adults, extra teeth erupt without any symptoms, but for children this can become a problem that needs to be addressed.

Supernumerary teeth erupt with the same symptoms as regular teeth, so the treatment for them is the same.

To lower the temperature, it is recommended to give your baby Paracetamol or Ibuprofen. If the child is very small, these drugs can be used in the form of suspensions or rectal suppositories. In addition to lowering the temperature, these medications do an excellent job of treating pain and inflammation.
To relieve gum pain, local anesthetics are used - ointments and gels (for example, Kalgel, Dentinox, Solokoseryl). These remedies cope well with painful sensations and slightly relieve inflammation.
Adults and children over 2 years of age can be treated with folk remedies: propolis, honey, decoctions of calendula, chamomile and lemon balm. Some decoctions help reduce pain and relieve inflammation. Traditional methods of treatment should be used only after consultation with your doctor.
If primary supernumerary teeth have partially erupted, stimulation of eruption is prescribed. For this purpose, vibration and electrical stimulation, as well as special massage, are used.

Causes of jaw abnormalities

To date, doctors have not reached a unanimous opinion about the causes of such an anomaly as hyperdontia. There are different hypotheses about this:

Atavism. Historians have proven that primitive people, due to the way of life they led, naturally had 36 tooth primordia. The results of studies of the remains of those times indicate that people had six incisors on the upper and lower jaws. Therefore, polyodontia is a kind of genetic anomaly that makes itself felt after thousands of years;
Many doctors are inclined to the theory that one embryo splits into several in the womb, when, in fact, they begin to form. This theory also states that an anomaly can develop throughout pregnancy if it was quite severe, the woman suffered serious illnesses or led an unhealthy lifestyle (bad habits, drugs, alcohol and others);

To date, research continues to establish the true cause of hyperdontia. Based on these data, modern doctors are more inclined to the second version than to the first.

What does the cost of treatment depend on?

The cost of treatment is determined by various factors, including the complexity of the anomaly and the method of its correction. If the patient does not show signs of deformation of the jaw arch, then simple removal will be required:

extraction of one supernumerary element costs around 1,500 rubles,
with its dystopia and retention, complex removal is required, and the cost of the procedure will vary from 3,500 to 15 thousand rubles.

The need for orthodontic correction significantly increases the cost of treatment. Here the price will depend on the specific technique, type of corrective structure, its materials and additional procedures.

Types of hyperdontia

Depending on the location of the supernumerary teeth, several types of polyodontia are distinguished:

Conical or awl-shaped tooth . In this case, excess rudiments erupt between the upper central and lateral incisors. The name of the anomaly comes from the peculiar shape of the supernumerary tooth, which looks like an awl. This form of hyperdontia is dangerous because the sharp end of the tooth often injures the mucous membrane, which is why an inflammatory process develops when an infection gets there.
Additional molars . Such teeth grow between the main molars, displacing the dentition from the correct position.
Extra fangs . This type of anomaly is typical for the upper jaw.
Supernumerary premolars . These additional teeth are located on the lower jaw. Each type of anomaly looks different depending on where and how the extra teeth are located. These differences can be clearly seen in the photo.

Diagnostic methods

Diagnosis of polyodontia is carried out exclusively by a specialized doctor - an orthodontist, who conducts a preliminary examination of the oral cavity and dentition, refers the patient to x-rays (orthopantomography) and analysis of anthropometric casts of teeth made of plaster. Such models are made for a more detailed study of a specific anomalous phenomenon, on the basis of which a diagnosis is then made and treatment is prescribed.

Table of normal human teeth. Deviation from the norm - polyodontia

When examining plaster models made on the basis of dental casts, the doctor measures the size of the teeth, and then analyzes the data obtained based on a special table by Wetzel and Ustimenko. The length of each row of teeth must be measured. This indicator may fluctuate depending on such characteristic individual characteristics of a person as crowding of teeth or the presence of large gaps between them. In the first case, the length will be less than normal, and in the second, a little longer. To diagnose asymmetry, the distance from the midline of the palate (or hyoid frenulum) to the far point of the dentition in one direction or the other is determined.

What to do?

The presence of supernumerary teeth is an abnormal phenomenon, so the issue of eliminating this problem must be resolved. How, this is another question, to give an unambiguous answer to which is impossible. As a rule, there can be several ways to solve a problem. The choice of treatment method depends on where the extra tooth is located, what shape it is, and what stage of eruption it is at.

Facilitating teething in baby

Drug treatment allows you to relieve unpleasant and painful symptoms during the eruption of excess buds. This option is the only one for children with baby teeth if the tooth is only at the eruption stage. When it finally germinates, it will be necessary to use more radical methods. The dentist prescribes medications that will help relieve pain, reduce fever and stop the inflammatory process in the soft tissues of the gums.

Simple tooth extraction

Surgery. This method is the fastest and most effective, since removing an extra tooth easily solves the problem and relieves a person from unpleasant sensations and discomfort. This treatment method is used when there is too little space in the dentition for an extra tooth or there is no space at all. Most often, supernumerary teeth are removed when there is crowding of the teeth. To free up some space in the dentition, the wisdom teeth are removed first, and if this was not enough, the premolars are also removed.

Braces and other orthodontic treatment methods

Orthodontic treatment is a method that involves correcting the bite, straightening the teeth, etc. The result is achieved by installing braces or other orthodontic structures that allow you to straighten crooked teeth and return them to their place, where they should be. The duration of wearing braces depends on many factors:

the age of the patient (children have their own specifics);
complexity of the situation;
locations of supernumerary teeth and others.

At the first and second stages of the disease, the doctor may decide to install special expansion plates or aligners. Can also apply the separation method.

Consequences of poor quality treatment

If the treatment is not well-carried out, impacted teeth will continue to interfere with the normal development of the bite and dentition, which causes a violation of chewing ability, leading to a number of problems with the gastrointestinal tract, and impaired diction, which negatively affects pronunciation and pronunciation. Also, after unsuccessful treatment, healthy teeth that are located next to the additional one may begin to deteriorate.

Preventive measures

The essence of preventing dental anomalies is to eliminate the possible causes of their appearance even at the stage of formation of rudiments, that is, all responsibility for possible dental anomalies depends entirely on the child’s mother.
To prevent this unpleasant phenomenon, you need to eat right, food should be balanced and healthy. It is important to give up bad habits and follow your doctor’s recommendations. When the baby is small, you need to make sure that he does not suck his finger or pacifier for more than a year and regularly take him for examinations to the dentist for timely detection and elimination of dental problems.

How is removal carried out?

If the abnormal tooth is single and it is not difficult to get to it using surgical instruments, then there will be no problems, and the tooth will be removed using a standard method. If there are several teeth, they are located in hard-to-reach places, have several roots, or have not fully erupted - in this case, removal is carried out as follows:

The doctor administers an anesthetic so that the patient does not experience pain during the procedure.
A small incision is made on the mucous membrane.
If the roots of the tooth are deep, the doctor may make a small hole using a special bur to provide access to the root system of the tooth.
The tooth and root are removed using forceps.
Next, the area is disinfected using antiseptic agents.
Stitches are applied.
To avoid complications, antibiotics, anti-inflammatory drugs, etc. may be prescribed.

Please note that before surgery, an X-ray diagnosis is required. In this way, the doctor assesses the condition of the root system and other features. Only after the diagnosis is carried out is the issue of tooth extraction decided.
