In dental practice, many problems of the oral cavity are connected precisely with wisdom teeth. During their growth, gums often become inflamed, there is fever, general malaise, and pain. Sometimes a tooth grows wrong. He touches the neighbors, again they bring pain. In the area of "wise" tooth infections and other unpleasant complications arise. A question creeps in whether wisdom teeth are needed at all. Many experts have already decided on the answer.
What are wisdom teeth?
Wisdom teeth, they are eights, as they are called by dentists – these are additional molars, that is, chewing teeth. They are located at the very end of the dentition. In total, each person has four wisdom teeth. They perform the same functions as other molars. Eights are designed for chewing and primary food processing. The appearance of such teeth is also related to their purpose. They are somewhat larger than premolars, canines and incisors. In the upper part of the molar a little flattened, as a result, formed a kind of platform through which food is crushed. Wisdom teeth begin to grow much later than all the others, because of what they got their name. Usually, all four teeth grow in the range of 18 to 25 years. The first to grow lower molars. Usually there are no problems with them. Somewhat later, the top eight begin to cut through. The third molar can have from two to five roots, but the three-root eights are more common. Two roots and more than three are the exception rather than the rule.
Do wisdom teeth need modern man?
The question of whether wisdom teeth are needed arises from the frequent problems associated with the growth of eights. All these complications are easily explained. In the process of evolution, the human dental system has changed a lot. We have changed the shape and size of some teeth, such as canines and upper incisors. Man’s jaw itself has become significantly less. Wisdom teeth, on the contrary, have suffered minimal changes over time. An additional pair of molars on each jaw was extremely necessary for our ancestors. Without them, it is simply impossible to chew on hard, solid food, which is predominantly part of the human diet. Since the development of the production of fire has changed a lot. Almost all food is subjected to heat treatment. It is far from being so tough as in the diet of our ancestors. Because of this, the need for third molars has become a big question. An even greater relevance of this topic is associated with the previously mentioned reduction in the size of the jaw of a person. Some modern people at the time of growth of the third molar does not have free space in the dentition. As a result of this, so-called rooted teeth are formed, that is, those whose growth something hinders. In the case of third molars, these can be the surrounding hard and soft tissues, the adjacent teeth. With its growth, the impacted tooth causes severe pain and other complications. Usually, such eights are immediately removed.
Based on all these observations, relatively recently wisdom teeth are attributed to the so-called rudimentary organs. This term refers to parts of our body that are no longer needed in the process of evolution. In addition to the third molars, this includes the tailbone, second eyelid, appendix, and more. From the moment when the third molars were attributed to the rudiments, the question of whether a wisdom tooth is needed, received an official answer. No, in fact, these teeth are no longer needed by man. An even greater confidence in this answer comes from the fact that already five percent of the entire population of the earth does not have wisdom teeth from birth. According to forecasts, this number will only increase, and within a few centuries, the third molars will become the exception rather than the rule.
