Friends who like watching Japanese dramas may find that there are quite a few Japanese people who are good-looking, but have crooked teeth. With a mouth open, the face value of the whole person has been reduced a lot in an instant, and this phenomenon of irregular teeth is not rare. Almost most Japanese people have irregular teeth. Why? Come and have a look. I. Historical reasons

When the economy and diet conditions are good, most countries and nations in the world will try their best to increase the proportion of meat in their diet, which is not only because meat is delicious, but also can improve the overall physical quality of a nation. However, there is a place in the world where people have taken the initiative not to eat meat for more than 1 years. This place is? Japan

was first issued by the ancient Japanese court in the eighth century? A meat ban? After that, the emperor continued to issue several letters, and the aristocratic class completely got rid of the meat-eating habit. In 1872, Emperor Meiji was officially dismissed? A meat ban? It's all over During this period of about 12 years of history,? Most? Japanese people mainly eat rice, vegetables and a small amount of fish.

Second, cultural differences

Apart from being unsightly, disordered teeth are hard to keep clean. However, many Japanese think that children with disordered teeth are cute, so some parents also think that children don't need to have their teeth corrected. First of all, there are fundamental differences in culture.

3. Eating Habits

Eating Habits Have you seen a typical Japanese meal? All soft protein foods, rice, tofu, natto? There is almost no need to bite or tear

Some experts believe that Japanese food is generally soft, and they seldom eat hard food. Especially before the rapid development of Japan's economy, Japanese people seldom eat meat. This kind of eating habit has caused the Japanese people's teeth to develop poorly and to be easily dislocated. In the final analysis, it is the gene and too little chewing.

Fourth, the cost of orthodontics is too high

The cost of orthodontics in Japan is still quite expensive, and it may cost 1, ~ 2, yuan at any time, and even it may cost several hundred thousand yuan in serious cases, which will vary greatly according to different regions! Moreover, correction is not included in medical insurance, and full payment is of course expensive. Japanese people all have this kind of teeth, so it doesn't matter if they feel it. The medical insurance is 7%, and the highest seems to be 8 thousand yen. That is to say, if you are seriously ill, you only need to pay 8 thousand yuan a month, and the rest will go to the government. This way, a serious illness will not bankrupt the whole family. Well, recently they have conquered leukemia and returned to medical insurance. With leukemia, it's only 8 thousand yen in Japan

Actually, orthodontics has something to do with skulls. Most Japanese people have relatively small maxillary bones and large mandibular planes, and the bones of orientals are harder than those of westerners. These factors virtually increase the difficulty of orthodontics.

In our country, we have been eating hard food since childhood, especially people in Northeast China, such as corn sticks and big ribs? It is an indispensable food for life. These hard foods fully squeezed the gums, which is a benign stimulus. However, Japanese people did not squeeze the gums because of insufficient chewing. When the teeth and jaws began to develop, Japanese food was not hard enough to promote the development of children's gums, so it developed into this situation.

So in China, many old people think that children's teeth are not fully developed and they can't eat hard food. In fact, children just need to eat some hard food if they want to grow up with good teeth!
