But they have some peculiar features. First, they have no dairy predecessors; secondly, are not always cut through. In norm they have to grow up at the person aged from 17 till 30 years, but in practice it can occur much later or not happen absolutely.
Set of the millennia back wisdom teeth took a worthy place in a tooth alignment of a jaw of the person which then was a little more as ancestors of people ate more rigid food and had a massive jaw. No problems with these teeth arose. But gradually the mankind passed to soft food which did not need to be chewed so carefully. Besides, the brain increased that affected a structure of a skull and the maxillofacial device. The third painters of steel ceased to participate in the act of chewing and became rudimentary, continuing to grow up in a jaw in which was already much less a place for them.
Therefore with a wisdom teething many people have problems. As they grow up late, in the conditions of shortage of a place, and overcoming a mechanical obstacle, cause painful feelings. Besides, often their growth is followed by various complications, for example, the third painter can reach the wrong position in a jaw and lay down horizontally or with an inclination. The lower teeth with a growth sometimes touch nerves or destroy the neighbors, grow towards a cheek or language, causing an inflammation and pain.

Though at other people these teeth grow without problems and are completely functional. Scientists cannot still tell, why the nature kept them. Stomatologists always express such opinion: if the wisdom tooth causes problems, it is desirable to remove it but when the reasons for concern are not present, and they participate in chewing process, it is not necessary to change anything. Besides, if earlier at the slightest complications the third painters unconditionally pulled out, today many dentists incline to thought that they need to try to be kept, after all they can become a good support for prosthetics of other teeth.
