I want to know everything. Wisdom teeth.
At what age do wisdom teeth appear?
What are they called that?
By the age of 18, a person, in most cases, has all permanent teeth. Only so-called wisdom teeth grow later – in 18 – 25 years. One person will be able to grow all four wisdom teeth, the other two or one. And for some people, they are completely absent, and this is not considered a deviation from the norm. The appearance of wisdom teeth is not always painless. From time to time, they erupt with great difficulty and put pressure on the adjacent teeth, traumatizing the surrounding soft tissues, leading to inflammation. It is difficult for a person to open his mouth, chew, say, the temperature may rise. In such cases, you need to consult a doctor. Often those with wisdom teeth erupt painfully, wondering if it is forbidden to remove them. Do not do this without medical evidence. Any tooth, and a wisdom tooth as well, are best preserved. In addition, if in old age there is a need for prosthetics, they can be very necessary.
An adult has 32 teeth. In front of the mouth are incisors and canines. On either side of the canines are small molars (premolars) and huge molars (molars). Each side of the jaw has three molars. Last third molars and wisdom teeth. Wisdom teeth appear on average from 16 to 25 years. Despite the fact that they can not cut through, they will be able to be in their infancy all their lives. There are four wisdom teeth in the mouth, on each jaw one on the right and on the left.
What does the loaded wisdom tooth mean?
Loaded in dentistry is called a tooth that did not completely cut through and did not take its place in the dentition. A tooth is said to be cut through, which protrudes above the level of the gum and reaches the antagonist-tooth of the opposite jaw. The circumstance of incomplete eruption (immersion) is that in the dentition it turned out that there is not enough space for this tooth, or that the wisdom tooth has an incorrect inclination. Loaded wisdom teeth in dentistry are divided in the direction of immersion. In the direction of immersion wisdom teeth are divided into 4 types: medial, distal, horizontal and vertical.
The simplest type of loaded wisdom teeth is those with medial immersion. The term "medial" indicates that the wisdom tooth is tilted forward, towards the front teeth. The term “distal” indicates that the wisdom tooth is tilted posteriorly. Wisdom teeth with vertical, horizontal, distal immersion are rarely seen.
In addition to this, wisdom teeth are divided into teeth with tissue and bone immersion. If the tooth remained in the thickness of the jaw, did not appear on the surface, then they talk about "bone immersion." If he went through the bone, but not completely cut through the gum, then it is called "tissue immersion."
What specific troubles can loaded wisdom teeth cause?
Because of wisdom teeth, the following troubles can occur: – Periconoritis – Wisdom tooth caries – Dystopia – Damage to the roots of adjacent teeth
Pericoronitis is an inflammation of the gums near a partially erupted tooth. This is the most frequently occurring complication associated with the eruption of the wisdom tooth. The tooth tends slowly. At first, one of its mounds appears, forming along with this a gap in the gum, while the other part of the tooth remains covered by it, forming a hood. A hood near a partially erupted tooth is a potential site of infection. Due to the difficulty of cleaning, food remains, foreign bodies accumulate in this place, and perfect conditions for the reproduction of bacteria appear, which leads to inflammation of the soft tissues around the wisdom tooth.
Wisdom tooth caries
We already know that caries appears on those tooth surfaces where plaque accumulates. Wisdom teeth are the farthest teeth and usually the access of a toothbrush to them is difficult. Permanent "nedovychischenie" plaque leads to its accumulation and the formation of caries. In addition, if the tooth partially erupted, it is under the hanging edge of the gums (hood), which also contributes to the accumulation of an enormous amount of plaque and interferes with cleaning the teeth. Quite often, the position of the wisdom tooth is such that it is not easy to clean the plaque between it and the neighboring tooth. In this case, caries can affect the contact surface not only of the wisdom tooth, but also nearby.
Dystopia – is the wrong position of the tooth in the dentition, which is manifested by its displacement towards the cheek, tongue, or turning about its axis. There is a conclusion that when teething a loaded wisdom tooth, while there is not enough space in the dentition, it presses on other teeth, as a result of which they shift and occupy the wrong position in the jaw.
Damage to the roots of adjacent teeth
As we have already mentioned, the wisdom tooth usually assumes an abnormal position in the jaw, up to its horizontal placement in the bone. Along with this, he can “lean” on the root of the adjacent tooth, and, during eruption, exert considerable pressure on him. As a result, the root of the adjacent tooth begins to dissolve.
At the time when to go to remove wisdom teeth?
There are no clear age parameters for removing wisdom teeth. It is better to remove loaded wisdom teeth at a young age,
Wisdom tooth extraction
The first stage of wisdom tooth extraction is anesthesia. At the end of anesthesia, the dentist proceeds to the removal of a loaded wisdom tooth.
To remove as little bone as possible, the dentist quite often removes the wisdom tooth into parts when it is removed. For this, dental burs are used. When the separation of the wisdom tooth is completed, the dentist removes each of these tooth parts with special tools.
At the end of the wisdom tooth extraction, the dentist places stitches on the area of the extracted tooth,
Some varieties of thread, which are made by these seams, subsequently dissolve by themselves, and the dentist himself removes non-dissolving seams. In most cases, non-dissolving stitches are used – the process of removing them is very simple and painless.
