Do I really need to remove wisdom teeth?
Wisdom teeth - the 8th tooth in a row (colloquial name is "eight") , the third molar (there are 12 in total), usually cut out at the age of 10-25 years (sometimes later, less often earlier, sometimes not cut out - they remain retined). Teeth that have not fully erupted are called "semi-retinated." A person’s wisdom teeth are not laid 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 as a variant of the norm, and not a pathology.
Simply put, the “eights”, which have long been unnecessary for a person to chew food normally, are recommended to be removed by the age of 25 years. But is it really necessary? We at Shram.kiev.ua analyzed different opinions on the removal of wisdom teeth. Here's what you need to know to make the right decision.
Currently, it is customary to believe that the third molar is a rudimentary organ due to changes in the diet (reduced consumption of solid and hard foods). In support of this, there has recently been an increase in cases of the absence of the germ of this tooth - the primary adentia of the third molar. This is also evidenced by dystopia, retention and, often, non-physiological form of the crown and roots of this tooth.
It is believed that wisdom teeth are called so because they appear much later than other teeth, at an age when the mental development of a person is considered perfect, and the development of human wisdom begins.
During eruption of the lower teeth of wisdom, when only a part of the tooth is visible, purulent inflammation often occurs in the formed pocket (“hood”) between the gum and the tooth - pericoronitis. For the treatment of pericoronitis, excision of the overhanging gums is recommended. If pericoronitis often recurs, then removal of the wisdom tooth is indicated.
It often happens that wisdom teeth due to lack of space in the jaw arch can erupt incorrectly and take a non-physiological position. Third molars, especially the upper ones, can cut into the buccal side and injure the mucous membrane of the cheek. It is also possible the eruption of the lower wisdom teeth with an inclination towards the adjacent tooth. Because of this, food enters the gap formed between the second and third molars. 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 are possible. Teeth with such pathologies are usually removed. 
Under normal eruption and physiological form, wisdom teeth can be used when prosthetics as a supporting tooth for a bridge or to fix a clasp or attachment on it in removable prosthetics.
Rarely (more often in representatives of the australoid race) there are additional, fourth molars.
No need to remove
- If they are healthy (no caries, gums around the tooth are not inflamed).
- Completely erupted.
- Correctly located: do not interfere with the normal functioning of adjacent teeth.
- They are easy to clean during daily oral hygiene.
Need to delete
- The teeth are completely hidden under the gum, but cannot cut through. In this case, they can contribute to the formation of a cyst, which, in turn, can destroy the roots of adjacent teeth.
- The teeth were not completely erupted. The difficulty of their hygiene, and therefore, a large accumulation of bacteria can lead to various diseases of the oral cavity.
- If there is not enough space for the tooth (the adjacent teeth sit very tightly), then the erupted wisdom tooth risks damaging the neighboring teeth.
- If you feel pain in the area of the wisdom tooth.
- The soft tissue next to the wisdom tooth is often infected.
- Tumors form.
- Gum disease occurs.
- Caries forms on adjacent teeth and begins to decay.
It's okay to leave your wisdom teeth if you are regularly checked by a dentist and take x-rays of the jaw.
In this case, you will be able to know in advance about a possible problem (improper growth of the wisdom tooth) and, 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 tissue has already been completely formed, the teeth are harder to remove and the tissues heal more slowly.
