Why do people have wisdom teeth? Is wisdom teeth really useless?

Wisdom teeth, I believe that people who grow up have basically left a bad impression on themselves. After growing wisdom teeth, it is not only difficult to eat, but also painful to drink water! Repetition is really bad, so the question is, why do people grow wisdom teeth? Is wisdom teeth really useless?

Answer the first question first. Why do people grow wisdom teeth?

This involves the issue of human evolution. Wisdom teeth are the product of human evolution. In addition, wisdom teeth, like the appendix, are the products left over from human evolution. At first, the appendix was used by humans to digest crude fiber, such as tree roots and other foods, while wisdom teeth were used to chew crude fiber, tree roots and bark and other foods to help the human digestive system.

But with the progress and development of human beings, the food they eat is more and more exquisite, and people gradually don't need these things. Although it is not necessary, there are still some genes that grow in this way, so some people will grow wisdom teeth under the influence of genetic genes. Usually, the time to grow wisdom teeth is between 16-30 years old, and it is also the last tooth in a person's life.

According to everyone's physique, the number, time and state of wisdom teeth growth will be different. People's mandible has become smaller, but there is almost no room for wisdom teeth to grow on the mandible, and there are no opposite teeth on the maxilla. Compared with ancient times, the alveolar bone of human beings has degenerated in different degrees in length, width and strength, so some wisdom teeth usually can't erupt normally and are located under the gingival tissue structure.

With evolution, food has become more and more refined. Although wisdom teeth have grown, the alveolar bone has degenerated. There are no teeth except fixed teeth. The length, width and strength of alveolar bone are not as good as before, so wisdom teeth will be squeezed to the end of mouth. Coupled with the obstruction of adjacent teeth and soft tissues, inflammation will occur, leading to many lives.

To answer the second question, are wisdom teeth really useless?

To sum up, wisdom teeth can be said to be organs abandoned by people in the process of human evolution. Generally, people with wisdom teeth feel the existence of wisdom teeth, usually because it brings them pain, such as toothache and gum inflammation.

When you go to the hospital for examination, the doctor will usually advise you to pull out your wisdom teeth. This is because wisdom teeth really affect your dental health. So which wisdom teeth must be pulled out?

Whether wisdom teeth should be pulled out depends not only on whether it hurts, but also on the dental tablets. Among them, it is best to remove wisdom teeth in the following situations:

1. Wisdom teeth are difficult to clean. Food residues are attached to wisdom teeth and are not easy to clean. Inflammation often occurs. If you don't diminish inflammation in time, wisdom teeth will swell and squeeze the teeth next to them, leading to toothache. I suggest you eliminate this situation.

2. decayed wisdom teeth. If wisdom teeth have cavities, it means that they are broken and need to be disposed of in time, otherwise it will also affect the surrounding teeth.

3. It is suggested that you also pull out the wisdom teeth against the adjacent teeth to prevent the consequences of dental caries and absorption.

4. If there are no teeth opposite the wisdom teeth, it is also recommended to pull them out, because there is no mutual support between the teeth that form the occlusal relationship, which is easy to cause the wisdom teeth to grow excessively.

Of course, there are also some wisdom teeth that don't need to be pulled out: if your wisdom teeth can erupt normally and establish an occlusal relationship, or at least it won't affect other teeth with the risk of pain and infection, you don't need to pull out, as long as you take good care of them.
