A wisdom tooth in a person is considered a rudimentary organ - it's 8 teeth in a row or 3 molars, which is cut through at the age of 14-25 years. Their appearance and structure do not differ from the usual molar tooth.
The structure of the human jaw changed over time, it became shorter, because people switched to soft food cooked on fire. As a result, the chewing load on the jaw dropped.
It turns out that the third molar may simply not have enough space in the dentition, as a result of which it will start to grow sideways or not at all disturb the person. But the root rudiments are laid by everyone in the period of intrauterine development.

Why is it "wise"?
"Wise" refers to teeth because they erupt already in adulthood, when the formation of mental maturity is over and begins to appear worldly wisdom.
Gears appear quickly, but can be a nuisance to a mature person for several years.
The process is accompanied by excruciating pain, fever, lethargy, numbness of the cheek, partial immobilization of the jaw, inflammation of the cervical lymph nodes.
If the tooth can not last for a long time, it is necessary to consult a dentist to dissect and anesthetize the gums to facilitate it.
Eight Placement
Where does the wisdom tooth grow, in which part of the dentition is it located? And they are located at the very end of the entire dentition on the upper and lower jaw.
Differ only in the structure of the roots - they are very curved and intertwined, so the treatment of their canals is very difficult, because dentists are often advised to remove such tooth immediately as it appeared. In addition, "beginners" often appear with carious cavities.
The third molars are the only ones that grow not in the place of the dairy ones, although they do not perform the masticatory function in full, as was the case with our ancestors, but they still continue to erupt, why does the wisdom tooth still grow, even though it already hasnot necessary?
The answer to the question is very simple: despite the evolutionary development and the reorganization of the human body under the habitat, our DNA still carries information about these teeth.
They deliver a lot of trouble to patients and dentists around the world, because they grow with pathologies and entail complications after eruption or removal.
Anatomical features of the
Wise representatives are extreme in the series on the upper and lower jaw, one to the left and to the right. Such an arrangement in hard-to-reach places creates difficulties in care and treatment.
Often, due to lack of space in the jawbone, they erupt inappropriately and occupy an unphysiological position.
Wisdom teeth, especially the upper ones, can grow into the buccal side and thereby injure the mucous membrane of the cheek. The lower ones are incised with a slope to the next neighbor.
As a result, a gap appears between them, into which food enters and it is very difficult to remove from there, resulting in the appearance of caries, the formation of tartar( hard plaque on the teeth) and plaques( soft plaque), pericoronitis and gingivitis. Such pathological disorders are difficult to treat, as a result of which the teeth are simply removed.
From zero to four "wise men" in the mouth
There is no exact norm about how much wisdom teeth there should be, nature includes the eruption of an additional four eights, but evolutionary development allows both the presence of all four, and their total absence or less. This is due to hereditary memory from generation to generation.
If one of close relatives eruption of "wise men" was accompanied by a strong inflammation or operations on their removal were involved, in the next generations rudiments may not form at all.
This is the reason for the appearance of people with one or two erupted "eight".And on the x-ray image there are no even rudiments of the root system.
Why are they needed now?
10 thousand years ago, wisdom teeth were for every adult, and now - 15% of people do not even have the rudiments of the "eights".They have lost their chewing function, because now they use cooked soft dishes.
But additional teeth also have useful functions:
- serves as a support for bridge prosthetics;
- is a deterrent for loosening adjacent teeth;
- act as a spare due to loss of the main chewing molars, as they partially perform the chewing function.
Healthy wisdom teeth in a person are very rare, so if they cut through without complications and exactly on the jaw, then they should not be removed - they will suddenly come in handy.
There are specific indications for removal:
- incorrect position;
- its presence provokes acute inflammation;
- the wrong position breaks the dentition;
- caries of the dental cavity and impossibility of treatment;
- strongly interferes with the adjacent tooth.
Do not be afraid of removal - the presence of such a tooth can be much more dangerous and painful. But if there is an opportunity to cure and keep the figure-eight, do not resort to removal at all.
Interesting information
Many interesting facts and beliefs are connected with the wisdom teeth.
All their own in the house
It is believed that if a person cut through all four "beginners", then they protect his family from trouble. The very owner is a very lucky person and achieves everything that he conceives.
In connection with the above belief, the patients "G8" were reluctant to remove - they were afraid to lose the printing of the lucky one. To prevent teeth from getting inconvenienced, they talked.
Until now, very rarely people are born who have as many as 32 teeth. They were considered sorcerers, cursed, or bearers of an important mission on Earth. At present, the presence of complete dentition is considered a symbol of determination, volitional character and independence.
In case of problems with the G8, they say that their master is indecisive, does not think about the meaning of life, about his mission to the world and does not make big plans.
Why Do You Need Wisdom Teeth
Japanese scientists have proven the benefit of the "Eight" because of the special stock of tissue in them, on the basis of which it is possible to create stem cells.
These cells carry the genetic information of the owner, as well as the entire prototype of all tissues of the human body, of which there are more than 240 species.
Stem cells are successfully used in the treatment of 70 diseases, where the treatment of tumor formations and blood cancer plays a significant role. They are used as an immune stimulant to improve vitality in cases of slow infections, decay of forces or chronic fatigue.
Stem cells have found application in sports medicine, because their effect significantly speeds up the process of wound healing and injuries. In cosmetology they are used for rejuvenation, strengthening of vitality and memory improvement. In the future, scientists plan, with the help of such useful components of the body, to create organs and tissues for transplantation to people who need them.
Such possible changes are necessary because of the lack of donors for transplanting internal organs, heart, bone marrow, which is very difficult to find even by medical indicators, and this technology will save many sick children and adults. Until now, stem cells have been extracted from the bone marrow and blood, and this is very painful and unsafe.
Scientists have found that soft pulp contains the material needed for further work in large quantities. It can be easily and painlessly removed if necessary, and in the case of removal of teeth should be frozen in case of an unforeseen situation.
This once again proves that in the human body there is nothing superfluous and everything that is given by nature is beneficial. Of course, problem wisdom teeth should be removed in order not to create complications.
But if they are healthy and normal, they are best preserved, it is good to take care of them and treat them, if possible. In life, there can be situations when the G-8 will maintain health and save a person's life.
