Is it really necessary to remove wisdom teeth?
Teeth of wisdom - the 8th tooth in a row (the common name for the "eight") , the third molar (12 in all), usually cut through at the age of 10-25 years (sometimes later, less often, sometimes not cut through - remain retouched). Not fully erupted teeth are called "semi-retinas". Wisdom teeth are laid in a person not in the prenatal period of development (in the womb), like others, but at the age of 4-5 years. Their absence is considered in dentistry a variant of the norm, and not a pathology.
Simply put, the G-8, which has long been unnecessary for a person for normal chewing food, is recommended to be removed by the age of 25 years. But is it really necessary? We in Shram.kiev.ua analyzed different opinions on the removal of wisdom teeth. That's what you need to know in order to make the right decision.
It is now accepted that the third molar is a vestigial organ due to changes in diet (reduction in the consumption of hard and hard foods). In support of this recent increase in the incidence of the absence of the rudiment of this tooth - the primary adentium of the third molar - has been observed lately. This is also evidenced by dystopia, retention and, often, the nonphysiological form of the crown and roots of this tooth.
It is believed that wisdom teeth are called so because they appear much later than the rest of the teeth, at an age when the person's mental development is considered perfect, and the development of human wisdom begins.
During the eruption of the lower wisdom teeth, when only a part of the tooth is visible, often there are purulent inflammations in the formed pocket ("hood") between the gum and the tooth - pericoronitis. For the treatment of pericoronitis, excision of the overhanging gum is recommended. If pericoronites often recur, then the removal of the wisdom tooth is shown.
It often happens that wisdom teeth due to lack of space in the jaw arc can incorrectly erupt and occupy a non-physiological position. Third molars, especially the upper molars, can erupt into the buccal side and injure the mucous membrane of the cheek. It is also possible to erode the lower wisdom teeth with a slant in the direction of the nearby tooth. Because of this, the resulting gap between the second and third molars gets food. Due to the impossibility of adequate hygienic treatment of this area, caries of the adjacent tooth, increased deposits of hard (tartar) and soft plaque, gingivitis or pericoronitis is possible. Teeth with such pathologies, as a rule, are removed. 
With a normal eruption and under the condition of a physiological form, wisdom teeth can be used in prosthetics as a supporting tooth for a bridge prosthesis or for fixing a clamper or an atmachine in a removable prosthesis on it.
Rare (more often in representatives of Australoid race) there are additional, fourth molars.
Do not need to delete
- If they are healthy (there is no caries, the gums around the tooth are not inflamed).
- Fully erupted.
- Correctly located: do not interfere with the normal functioning of neighboring teeth.
- They are easy to clean during daily oral hygiene.
It is necessary to delete
- Teeth completely hidden under the gum, but can not erupt. In this case, they can contribute to the formation of a cyst, which, in turn, can destroy the roots of neighboring teeth.
- The teeth did not erupt completely. Difficulty of their hygiene, and consequently, a large accumulation of bacteria can lead to various diseases of the oral cavity.
- If there is not enough space for the tooth (adjacent teeth sit very tightly), the erupting wisdom tooth runs the risk of damaging neighboring teeth.
- If you feel pain in the area of wisdom tooth.
- Soft tissues next to the wisdom tooth are often infected.
- Tumors are formed.
- There is inflammation of the gums.
- Caries are formed on the adjacent teeth, they begin to break down.
There is nothing wrong with leaving wisdom teeth, if you regularly check with a dentist and take x-rays of the jaw.
In this case, you can learn in advance about a possible problem (improper growth of the wisdom tooth) and, in order to avoid it, perform an operation to remove the tooth.
Doctors recommend doing this as soon as possible, because after 25 years, when all the bone tissues are finally formed, the teeth are more difficult to remove and the tissues heal more slowly.
