What are wisdom teeth and why are they called wisdom teeth?

"Wisdom teeth" are wisdom teeth, which are the backmost molars in the mouth, which generally grow out at the age of 18-22, and some people will never grow out. It is said that people with "wisdom teeth" are smart!

Problem description: Why are they called wisdom teeth Recently, I have wisdom teeth, which is simply painful.

May I ask what wisdom is embodied in?

Analysis: Wisdom teeth are called third molars, also known as wisdom teeth. Wisdom teeth are the latest teeth to develop and erupt, and wisdom teeth are often hindered due to lack of space during the eruption process, which can lead to various complications.

In the long years of evolution, in order to adapt to the changes in the living environment, the organs of the animal must be changed accordingly. Due to the use of fire, the food changes from raw to cooked, from coarse to fine, from hard to soft, resulting in an increasingly weakened function of the chewing organs, resulting in a genetic transformation of degenerative shrinkage. This degeneration and shrinkage of the chewing organs presents an imbalance, that is, the muscles come first, the jaw bone comes second, and the teeth come again, so the jaw bone cannot accommodate all the teeth.

This contradiction between tooth volume and bone mass is concentrated in the wisdom tooth that erupts at the earliest. Wisdom teeth are the teeth with the most tendency to degenerate, and compared with the second molars, their morphology is smaller, the cusps are reduced, the roots tend to fuse, the crown is tilted, and the cleft of the occlusal surface disappears significantly; After wisdom teeth erupt, they rarely establish a normal occlusal relationship, and most of them are inclined or semi-ambushed, and cannot be used for occlusion. It can be said that the congenital absence of wisdom teeth is a manifestation of the degeneration of the human chewing organs.

The development of teeth is divided into three stages: growth stage, calcification stage, and eruption stage. Wisdom tooth germs occur before the age of 5 years; The time when hard tissue begins to form is 7-9 years old in the upper jaw and 8-10 years old in the lower jaw; The age of eruption is 17-21 years old, and this standard is adopted by countries around the world. There are great individual differences in the development of wisdom teeth, and these differences are caused by both genetic and environmental factors, such as race, gender, nutrition, food status, masticatory muscle function, temperature, disease, etc., and the influence of environmental factors is more common.

Because it is a tooth that grows after adulthood, it is called wisdom teeth

In medicine, wisdom teeth are also called third molars, the eighth tooth counted inward from between the two front teeth, wisdom teeth are the last permanent teeth to erupt among the 32 permanent teeth of human beings, located at the back of the upper and lower left and right arches. Because most of the wisdom teeth will be around the age of 16 to 24 when they erupt, after the growth of people's wisdom, they are also known as wisdom teeth, referred to as wisdom teeth. In the process of human evolution, due to the finer and finer food, the burden on the jaw bone is reduced accordingly, resulting in the continuous reduction of the jaw bone mass, but the volume of the tooth does not decrease, and finally the position of the tooth eruption is insufficient, and the final eruption of the third molar is most likely to form wisdom tooth pericoronitis, which is the main reason for the abnormal position of wisdom tooth eruption.

Origin of wisdom teethWisdom teeth refer to the four third molars in the human mouth, one at the innermost alveolar bone, one on the left, one on the left, one on the left. Because these four third molars begin to erupt at the age of 20, when people's physical and psychological development is close to maturity, they are regarded as a symbol of "wisdom arrival", so they are called "wisdom teeth" - wisdom teeth.

Wisdom teeth, the third largest molar, commonly known as wisdom teeth, standing teeth, and end teeth, are the teeth closest to the throat in the mouth, if all of them grow out, there are a total of 4, two in the upper and lower jaws, and generally grow at the age of 16 or later. In contrast to baby teeth that erupt in early childhood and permanent teeth that are replaced in childhood, wisdom teeth usually erupt when the human mind is already maturing, hence the name. In terms of wisdom tooth growth, there are great individual differences, some people before the age of 20, some people only grow older, and some people do not grow for life, which is normal.

In addition, not all four wisdom teeth will necessarily grow completely, some people's wisdom teeth may only grow 1 or 2, and some wisdom teeth may not grow even halfway through, which is called wisdom tooth impaction. Wisdom teeth are located from between the front teeth, counting the number of teeth from one front tooth to the inside, and if there is an eighth tooth, it is a wisdom tooth.

1. Wisdom teeth are also called third molars, and some places will call wisdom teeth wisdom teeth.

2. Wisdom teeth are about 18-25 years old, behind the last molar of human beings, and the number of teeth erupted has great individual differences. A small number of people will have the condition of missing wisdom teeth, in addition, the number of wisdom teeth in the population with wisdom teeth also varies greatly, ranging from 0 to 4, but the vast majority of wisdom teeth are symmetrically distributed.

3. In the process of wisdom tooth eruption, it is likely to cause wisdom tooth pericoronitis, and even the phenomenon of impacted eruption, and extraction can be considered for this type of tooth.
