Third molars or "wisdom teeth", so called for late teething, is one example of evolution taking place before our eyes. They are located between the second molars and the ascending ramus of the jaw; the upper and lower wisdom teeth are often not in contact with each other, respectively, are not cleaned; in sweet enamel, which is quite thin there, food particles remain, bacteria multiply - and, as a result, the enamel is affected by caries. It seems that they are completely unnecessary.

However, this was not always the case, the jaw used to be larger, like the third molars, which were the largest teeth. The ancestors of modern man did not experience any problems from these teeth and even depended on them.

However, with the transition to high-calorie meat food, the advent of tools and heat treatment of food, the size of the teeth became less relevant. About two million years ago, our ancestors gradually began to be born without this tooth.
Now these teeth are irrelevant, food does not require a third molar and, in general, wisdom teeth are considered a rudiment.

If a tooth grows crookedly, or there are other reasons for removal, do not be afraid of this small and uncomplicated operation.

I agree with Olga Golts.

I won't go into the theory of evolution, I'm just an engineer.

I'll tell you a case from my life.

In elementary school I got a 4-ku. The 5 crawled safely into its place and all the teeth, respectively, moved. By the prom came "wise". For more than a dozen years I have chewed on it. A year ago, thinking that this is 7, they were going to treat.)))))

As a result, I will prosthetics, but this has nothing to do with the case.

So the theory arose that 8 is a spare wheel.

Healthy teeth everyone!

Wisdom teeth usually grow after 20 years. Now the level of dental care and dentistry is so high that at this age it is rare for anyone to have more teeth missing. But mankind has also known such times when by the age of 30 the dentition was so thin that it was difficult to chew food. Naturally, they did not even hear about prosthetics then, so the evolutionarily conceived appearance of four new teeth was very, very useful.

It is obvious that it fulfills its function of chewing.

Due to the evolutionary ratio of the sizes of the facial and cerebral parts of the skull, these teeth sometimes do not have enough space in the dentition, since massive jaws now, with biological point of view, not in favor: due to the heat treatment of products during cooking, there is practically no coarse food that requires thorough grinding. In childhood and adolescence, the stimulating growth and development of the jaws, the load on the dentition is not high, since children are fed soft food, and almost no one gnaws jerky and cartilage like babies of nomadic peoples. Also, the proportion of naturally breastfed babies in whom sucking stimulates the growth zones of the jaw bones has also decreased. Well, sexual selection plays a negligible role in reducing the number of owners of massive jaws, but this can be neglected against the background of the above reasons.
