A wisdom tooth is an ordinary multi-root tooth, like the others. Dentists call such teeth "eights", because if you draw a vertical line, separating the right and left parts of the face, then the wisdom teeth will be the eighth in a row. How many wisdom teeth does a person have? Norms for their number does not exist. Nature endowed each person with two pairs of "eights", two teeth per jaw. But the fact is that in the course of evolution, the human jaw has undergone changes and has become slightly smaller (1 cm) than our ancestors. This is due to the transition to a softer and thermally processed food, which reduced the load on the jaw.
And nowadays they are not four, but less, in some people they may not be altogether. This is due, in particular, the work of hereditary memory. If the next of kin suffered from the disease during the eruption of the “eights”, and the treatment was radical, then in subsequent generations the beginnings may not be formed. This is confirmed by the frequent cases in which the series contains only one cut through "eight", and the X-ray data demonstrate the absence of even the rudiments of "twin." A man of the eight will grow or not, how many of them there will be, how they will be located, depends on the following factors:
- From heredity
- On the number of primordia,
- From the shape and size of the jaws.

When to wait for teething wisdom?
The process of changing dairy to permanent occurs in the interval from 6 years to 13 years. Wisdom teeth are formed for several decades, replacing the stage of development and peace. By the age of three years, the rudiments of all the indigenous ones are formed; it is at this time that it is determined how many rudiments of the “eights” are laid and whether at least one will grow. How long does a wisdom tooth grow? By the age of twelve, all the indigenous people are already taking part in chewing food, and the G8 is at the stage of completion of the crown formation.
How many years to wait for the eruption of "eights"? They are usually erupt by the age of 22. Usually, if wisdom teeth have not grown by the age of 27, then they cannot be expected. The cutting time depends on the size of the jaw and the location for its location. The cutting process under favorable conditions takes an average of one and a half months. The roots continue to form over 4 years after eruption.
Why is the name of the "eights"? The age of the cutting of wisdom teeth is characterized by formed and developed organs and body systems, from this period the aging of the body begins. Wisdom teeth appear to the period of maturity of the organism, hence their name.
Is there a need for such teeth?
As known, there is nothing superfluous in nature. Although wisdom teeth have lost their function in the course of evolution, however, they can benefit in old age. If the owner loses the seventh tooth, then the wisdom teeth can partly take over the chewing function, and also come in handy in bridge prosthetics, becoming a support.
If the G8s are healthy and well positioned, they can be an excellent complement to the dentition, but in most cases they are a source of problems. Many complications occur in their eruption.
Eruption complications
Most common tissue inflammationsurrounding a tooth. The growth of a wisdom tooth is accompanied by the appearance of a tubercle from the gingival mucosa.Such a shell has the name "Hood". The "eight", covered with such a "hood", is under pressure and is injured by solid food, this contributes to the adherence of bacteria that cause inflammation. If food gets under the “hood”, then favorable conditions for bacteria come, which, in turn, carries the risk of pericoronitis, i.e. purulent inflammation.
Manifestations of pericoronaritis
In the area of growing wisdom tooth pain begins to grow. It is very tangible and is able to give to the temple, ear. Pain can occur when yawning, swallowing and opening the mouth. It may seem like a sore throat or cheek, and not a wisdom tooth. The muscles of the face and lymph nodes may be involved in the painful process. Inflammation of the "eight" can affect the entire body as a whole, which reacts with fever and headache. The gum area swells, the mucous membrane has a red appearance and is painful; when pressed, pus is released from under the hood.
What is forbidden
- To prevent the spread of infection should not apply heat to the cheek, as well as warm water, rinse your mouth. Otherwise, bone tissue suppuration may occur.
- You do not need to put pain pills on the area of the inflamed gums, as you will not be able to remove the pain, and an ulcer will appear at this place.
- In no case do not listen to the advice of relatives and friends, something may have helped them, but without an accurate diagnosis and the causes of inflammation of the wisdom tooth, it is not worth risking your health.
What do we have to do?
- First you need to make a visit to the dental surgeon.
- Before that, it is possible to take painkillers inside (Ketorol, Analgin, etc.).
- It is necessary to make a cold solution and rinse their mouth. (Put 1 teaspoon of salt and 1 teaspoon of soda in a glass of water).
The doctor treats this pathology by opening the “hood”, washing the cavity and prescribing anesthetics and anti-inflammatory drugs. Antibiotics are prescribed for large quantities of pus. If a gum is inflamed the second time, this time shows the removal of the "eight".
Caries. When a wisdom tooth is shown on it caries is often observed. The disease develops from inadequate hygiene of this area, because the location is difficult to access. Often appear with already damaged enamel and the initial signs of the disease. "Eights" are often close to the adjacent teeth, which is why caries can go to them. Therefore, the dentist must decide: to treat or removal will be the best way.
Malocclusion Very often, there is not enough space in the jaw and the extreme teeth begin to put pressure on the "sevens", which, in turn, support the "sixes", a chain reaction occurs, eventually, in the center of the jaw, the crowding of the front teeth and the violation of their correct location are observed. The wrong bite develops.
Pressure on the "seven". The height of the "eight" sometimes accompanied by dull painwhich may occur at intervals or be constant. Often it gives to the ear, temple, or jaw. If there are no external manifestations, such as swollen gum or red, then you need to take a picture. This event will allow you to see the direction of growth and make a decision on its removal or abandonment.
Inflammation of the branches of the trigeminal nerve manifested by twitching of muscles and pain syndromes in the face. They are provoked by their daily hygiene measures, such as brushing their teeth, shaving, washing. Manifestations go away with tooth extraction and proper anti-inflammatory treatment.
Cyst jaw. "Eight" growing very slowlyThat is why it can be a source of cyst formation in the lower jaw. If its progression is not observed, the disease is asymptomatic, and its presence is detected during the taking of a picture of the jaw for other reasons. Cyst growth leads to pain in the gum area.The cyst often accumulates fluid, which eats away the walls of the tooth. If an infection gets into the cyst, then a flux (abscess) develops. In this case, the "eight" is removed.
Tissue injury. If a wisdom tooth grows wrong, for example, on the cheek, it constantly injures this area while chewing. This can lead to an ulcer. If it does heal, it leads to the formation of scars, which are again injured by incorrectly positioned “eights”. This traumatic process can lead to the development of a tumor at the ulcer site. In such a case, the G-8s will usually be deleted.
