Opinion of foreign dentists

It is worth mentioning that in many countriespatients do not even have a question about whether they need wisdom teeth. The answer is obvious - no. In Europe and the US, doctors remove third molars (the natural name for wisdom teeth) as soon as they become visible. The procedure for removing the wisdom tooth is even included in medical insurance. In our country this problem is solved in different ways. Most often, doctors insist on the removal of the tooth, but the patient has the right to decide for himself how to proceed.

What is the wisdom tooth?

Wisdom teeth are 4 molars that are inthe end of the upper and lower dentition, are located closer to the auricle and jawbone. The people call it the "eight". The scientific name is the third molar.

Appearance

To understand why a wisdom tooth is needed, it is worthto figure out when he appears and who. We know that an adult has 32 teeth, but only 28 teeth take part in the chewing process. This means that 4 teeth are not needed for this process, which are located along the edges of the upper and lower jaws, that is, wisdom teeth. They appear much later than other teeth, from about 16 to 26 years. They received their popular name because of the symbolic "wisdom" that a person attains by entering into adulthood. Although it is clear that the "adult" does not yet mean "conscious", "reasonable" and "wise". The appearance of wisdom teeth can cause a number of oral problems. It is also worth noting that the appearance process can take a few years.

The wisdom tooth: why is it needed?

Functional property of wisdom teeth is stillcompletely not studied. Scientists and dentists consider them a rudimentary organ in which a person no longer needs. It is interesting that the third molars do not develop at all. About half of the population does not know the problems with wisdom teeth, because she does not have them. This leads scientists to the idea that in the near future they will not have anyone.

There is a common opinion. Why do you need wisdom teeth in fact? It is believed that in the past a person needed all 32 teeth to chew on hard food. Modern man consumes food much softer, processed, refined. Now, only 28 teeth are enough for chewing food.

Why does it hurt?

Why do you need wisdom teeth if they deliverso much inconvenience? It is believed that due to the fact that the food has become softer, the jaw has atrophied and changed. It decreased in size, although the teeth remained the same. It turns out that the third molars simply do not fit in the oral cavity, so they bring so many problems.

In defense of

Still, there are several reasons whywisdom teeth are needed by man. In the process of chewing food to a modern person, it is not absolutely necessary to have third molars, but they perform a number of other important functions. Why do you need to remove wisdom teeth, if they can be the only way out with some problems? For example, with dental prosthetics, third molars can become a support, which will greatly simplify the procedure. The second reason is that wisdom teeth restrain other teeth from excessive growth. They "hold" the jaw, not letting the teeth grow as if it were horrible. And the last argument: when an elderly person loses a lot of teeth, it is the third molars that can replace chewing.

It becomes clear that the role of wisdom teeth is significant. They are something like a "reserve", which can always help out.

If you do not treat such teeth in time, the gums around them swell, which may require immediate surgeon intervention. Even if the wisdom teeth do not disturb, they can contribute to the development of caries. It is difficult to clean them thoroughly or to cure them, even in the doctor's office due to a difficult location. Very often cases when tooth decay from wisdom teeth is transferred to other healthy ones. If treatment is impossible, pulpitis threatens - inflammation of the dental nerve.

Long eruption of wisdom teeth is also fraught. There are a lot of bacteria, food and plaque accumulating there. This can lead to gingivitis and halitosis. Even worse is when the tooth has grown only half. Pericoronitis may occur, an inflammation of the gum that can go to the bone. Because the wisdom tooth is too big, it presses on the neighboring, destroying their enamel.
