An orthodontist makes such a diagnosis with code K07.3 according to ICD-10 (International Classification of Diseases, 10th revision) if the tooth has erupted with an inclination or displacement, or has completely appeared outside the dental arch. This mainly happens to the lower eighth molars, incisors and canines.
A companion to dystopia can be other anomalies in the position of the teeth - crowding, displaced or open bite, as well as retention.
Reasons for appearance
- Heredity. If a child inherited, for example, large teeth from his father and a small jaw from his mother, dystopia cannot be avoided. In addition, it can be inherited on its own.
- Atypical formation of dental tissue primordia in the embryo.
- Injuries and bad habits: prolonged use of a pacifier, the habit of biting a pencil, etc.
- Early removal of baby teeth.
- Peculiarities of eruption time. For example, if fangs appear late, that is, after 9 years, there may no longer be room for them in the arch.
- Dystopia is often caused by polyodontia (“extra teeth”), macrodentia (abnormally large teeth), partial absence of teeth or a sharp discrepancy between the size of primary and permanent teeth.
Types of dystopia
Depending on how and where the crown is displaced, several types of pathology are distinguished:
- A tilt towards the vestibule of the mouth means that we are talking about the vestibular position of the dystopic tooth, and if, on the contrary, in the depths of the oral cavity, we are talking about the oral position.
- When the body of the tooth is completely located outside the arch and moves forward or backward, the dentist will note in the chart the presence of a mesial or distal position, respectively.
- Is the newbie cutting higher than the rest? – Such an anomaly will be called supraposition. If lower, infra position.
- Rare anomalies are torto- and transposition. In the first case, the tooth rotates around its axis, in the second, it changes places with its neighbor, for example, a canine takes the place of a premolar.
Depending on which tooth is in the wrong position, dystopia of incisors, canines, molars and premolars or “eights” is distinguished.
Postoperative period - what to do after extraction
Above, we looked at how problem teeth are removed, and now let’s move on to the important question of how to care for the socket and oral cavity after the procedure. This period plays a very important role and requires the patient to responsibly comply with the doctor’s instructions. Otherwise, infection may seep into the wound and cause complications.
So, dental experts provide the following recommendations for oral care after a complex extraction:
- for the first 3-4 hours you will have to give up eating, drinking and smoking,
- when carrying out hygienic procedures, including with rinsing solutions prescribed by a doctor, extreme caution must be observed,
- in the first days it is better to try to chew food on the opposite side,
- preference should be given to a product that is not too hard at room temperature,
- You will have to temporarily limit physical activity, give up a hot bath, visit the bathhouse and sauna.
For the first time after removal, you should avoid exercising and eating.
It is very important to monitor the integrity of the blood clot that forms in the socket after the bleeding stops, a couple of hours after the operation. This clot serves as a protective barrier, eliminating the risk of mechanical injury to tissues or infection. Therefore, in the first couple of days, instead of rinsing, you need to do oral baths with the prescribed antiseptic solution. Too intense rinsing and anything that can create a vacuum in the mouth should be banned in the near future.
Dystopic wisdom tooth
The eighth molars are the last to appear, and that is why they are associated with the greatest risk of dystopia.
The bone tissue has already been formed, and often there is no longer room for a newcomer in the dental arch. In addition, any indigenous is preceded by a dairy pioneer who “breaks” the path. The “wise” molar does not have such an assistant, just as there are no neighboring teeth that determine the correct position on the arch.
Dystopic wisdom tooth
Possible complications
A dystopic tooth can injure the oral mucosa, tongue and cheeks, resulting in decubital ulcers.
Anomalies in the position of crowns and malocclusion are a common cause of caries: oral hygiene becomes more complicated, and it is difficult to completely remove plaque and food debris from the interdental spaces.
Another complication is problems with diction and chewing food.
Also, inflammation often occurs above the part of the crown that has not yet erupted - pericoronitis. And in the most difficult cases, the “problem” tooth erupts outside the alveolar arch, which, of course, entails not only serious discomfort, but also diseases of other organs.

Treatment of dystopia
The method of therapy depends on the condition of the dystopic tooth and its useful load. Sometimes it is enough just to polish the sharp edges and give it a shape that will not injure the mucous membrane.
Most often, when a tooth is in an incorrect position, they resort to orthodontic treatment methods. Braces allow you to cope with serious malocclusions. If there is no room for a tooth, and this is, for example, a canine that is important from the point of view of functionality and aesthetics, then you will have to remove its neighbors and only then begin orthodontic treatment.
Treatment of dystopia with braces
When to remove a dystopic tooth
Removal is not a pleasant procedure, and therefore is always a last resort. It is used in the following cases:
- in the presence of pulpitis, periodontitis or cysts;
- if it is a wisdom tooth complicating the treatment of caries of the seventh molars;
- when the anomaly is accompanied by osteomyelitis or periostitis;
- if surrounding tissues are seriously injured.
If there are no such indications, the dentist will do everything possible to save the dystopic tooth. Note that it is optimal to undergo treatment before the end of growth of the facial skeleton, that is, up to 14-16 years. In this case, you will see results faster, and they will be noticeably better than if you consult a specialist later.

Diagnostics
In most cases, pathological tooth root resorption is asymptomatic and is detected during routine radiographic examination. At the present stage, the number of detected resorptions has increased due to the introduction of cone beam computed tomography (CBCT).
In his study, K. Aziz [9] proved that a two-dimensional image often does not reflect the true nature or extent of the resorptive process.
K. Vasconcelos [67] in his report indicates that CBCT helps to determine the presence and topography of the resorptive area of the root, which determines treatment tactics.
