Do I really need to remove wisdom teeth?
Wisdom teeth - the 8th tooth in a row (common name “eight”) , the third molar (12 in total), usually erupt at the age of 10-25 years (sometimes later, less often earlier, sometimes not erupted - remain impacted). Not fully cut teeth are called “polyurethinized”. 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 in dentistry is considered a variant of the norm, and not a pathology.
Simply put, “eights”, which a person has not needed for a long time for normal chewing of food, are recommended to be removed by the age of 25 years. But is it necessary? We at Shram.kiev.ua analyzed different opinions on wisdom teeth removal. Here's what you need to know to make the right decision.
At present, it is customary to believe that the third molar is a vestigial organ due to a change in diet (decrease in the consumption of solid and hard foods). In confirmation of this, there has recently been an increase in the absence of an embryo of this tooth, the primary edentulous third molar. Dystopia, retention and, often, the non-physiological form of the crown and roots of this tooth also testify to this.
It is believed that wisdom teeth are called so because they appear much later than other teeth, at the age when a person’s mental development is considered perfect, and the development of a person’s wisdom begins.
During the eruption of the lower wisdom teeth, when only a part of the tooth is visible, purulent inflammation often occurs in the resulting pocket (“hood”) between the gum and the tooth - pericoronitis. For the treatment of pericoronitis, excision of the hanging gums is recommended. If pericoronitis often recurs, then a wisdom tooth removal is indicated.
It often happens that wisdom teeth, due to a lack of space in the jaw arch, can erupt incorrectly and take an unphysiological position. Third molars, especially the upper ones, can cut into the cheek side and injure the cheek mucosa. It is also possible the eruption of the lower wisdom teeth with a slope in the direction of the adjacent tooth. Because of this, food gets into the gap between the second and third molars. In view of the impossibility of adequate hygienic treatment of this area, caries of the adjacent tooth, increased deposits of hard (tartar) and mild dental plaque, gingivitis or pericoronitis are possible. Teeth with such pathologies are usually removed. 
Under normal eruption and under physiological conditions, wisdom teeth can be used during prosthetics as a supporting tooth for a bridge-like prosthesis or for fixing a klammer or attachment on it in a removable prosthesis.
Rarely (more often among representatives of the Australoid race) additional, fourth molars are found.
No need to delete
- If they are healthy (no caries, the gums around the tooth are not inflamed).
- Completely cut through.
- Correctly located: do not interfere with the normal functioning of the adjacent teeth.
- They are easy to clean during daily oral hygiene.
Need to delete
- The teeth are completely hidden under the gum, but cannot erupt. In this case, they can contribute to the formation of a cyst, which, in turn, can destroy the roots of adjacent teeth.
- Teeth not completely cut. The 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 (the adjacent teeth are sitting very tightly), then the wisdom tooth that has erupted will risk damaging the adjacent teeth.
- If you feel pain in the area of the wisdom tooth.
- The soft tissue near the wisdom tooth is often infected.
- Tumors are formed.
- Gum disease occurs.
- Caries form on adjacent teeth, they begin to break down.
There is nothing wrong with leaving wisdom teeth if you regularly check with your dentist and take x-ray pictures of your jaw.
In this case, you will be able to find out in advance about a possible problem (improper growth of a wisdom tooth) and, in order to avoid it, to perform an operation to remove a tooth.
Doctors recommend doing it as early as possible, because after 25 years, when all the bone tissue is already completely formed, the teeth are harder to remove and the tissues heal more slowly.
