Why do children lose their teeth?

Parents with children must know that babies usually start to change their teeth intermittently at the age of six or seven. Have you ever wondered why children lose their teeth? Let's talk about it below.

We humans have two pairs of teeth, which are different from other organs of the body and need an "inheritance". One pair is called deciduous teeth, which are small but not wear-resistant. When the size, quantity and strength of periodontal tissue of deciduous teeth can not adapt to the growing jaw, teeth will be changed.

As we all know, people only change their teeth twice in their lives, once for primary teeth and once for permanent teeth. In the process of human evolution, only a pair of deciduous teeth embryos and a pair of smaller permanent teeth embryos, that is, double dentition, have been formed, so human beings can only change their teeth twice. If the teeth are well protected, a set of permanent teeth can be used for a lifetime, just like a person has only two hands. Some things don't need to be too entangled, which can't be changed. The key now is to protect your teeth.

We humans have two pairs of teeth, which are different from other organs of the body and need an "inheritance". A pair of deciduous teeth are called deciduous teeth, because they begin to grow when they are suckled, so they are called deciduous teeth. They are small and wear-resistant, totaling 20. The other pair is permanent teeth, which gradually replace deciduous teeth from the age of 6. With the increase of age, people's skull bones keep growing, while teeth don't. Therefore, when the size and number of deciduous teeth and the strength of periodontal tissue can't adapt to the growing jaw, teeth will be changed.

Permanent teeth are teeth that never change for life and have strong chewing function. However, if you don't pay attention to oral hygiene and get dental disease, your permanent teeth will fall off in advance. If a permanent tooth is lost, there will be no replacement tooth and no new tooth will grow. The importance of permanent teeth can be imagined.

Many people live to be 80 or 90 years old, and their teeth are still good. Some people lose several teeth in their forties and fifties. Many people think it is a normal physiological scene. In fact, it is not necessarily true that the teeth are not old, but they are sick. Teeth are like a big tree, and gums are like the soil on which big trees live. Tooth inflammation is easily overlooked in the early stage, which leads to the continuous development of the disease. Because the root bacteria can't be removed, the soil around the tree is constantly scraped up, and finally the root is exposed, and the root soil is separated, so the tree can no longer stand. Therefore, we must pay attention to keeping our mouth clean and taking good care of our teeth. Once there is an oral problem, we must find out the reason in time and treat it in time, without delay, otherwise once we lose our permanent teeth, we will never have them again in this life.
