Why are the teeth of Japanese girls so ugly?
Friends who pay attention to Japanese culture, especially the Japanese entertainment circle, will find that many handsome and beautiful stars in Japan have a crooked tooth hidden under their handsome and beautiful appearance. Once they spoke, the ugly tooth instantly lowered the man's style.

Some time ago, Emiri Katou, a famous Bel Canto actress, successfully corrected her teeth, changed the unnatural shut-up state when taking pictures before, and the whole person's temperament rose to a higher level.

A beautiful voice actor always shuts his mouth unnaturally when taking pictures before orthodontics.

It's scary to laugh suddenly.

Does the temperament change greatly after correction?

Japanese teeth are ugly and irregular, which has become a feature of them, which makes us people with good teeth very confused:

Why do their people have such ugly teeth in Japan, where the economy is so developed and life is so rich?

Longgong biology

After the Japanese defeat in World War II, many orphans lived in China and were adopted by kind people in China, known as "China adherents" in history. These people returned to Japan after the establishment of diplomatic relations between China and Japan, and although there are some malnourished people among them, their teeth are more beautiful and much neater than the average Japanese.

Japanese custom is proud of neat and white teeth, so various toothbrushes and toothpastes developed in the market emerge in an endless stream, and dentists also earn a lot of money, but the effect is not very good. It is said that these "leftover men" have no conditions to enjoy these good conditions, but their teeth are even neater than the average Japanese, which makes people feel strange.

Further investigation shows that although dental diseases are common in China, the proportion of people with neat teeth is much higher than that in Japan, even for China expatriates living in Japan. It can be seen that uneven teeth are not caused by racial reasons.

After studying the living habits of the two countries, Professor Lai Cun was enlightened. The initial problem is that people in China have the habit of eating bones and meat.

Braised pork ribs, rock sugar elbows, these typical Chinese dishes all need to "chew bones". Even overseas, China people with a conservative diet still keep the habit of eating meat with bones.

From a medical point of view, things are easy to explain. Because children chew bones, their gums will be strongly squeezed. This kind of squeezing is a benign stimulus to the gums, which can force the gums to grow fully, and the teeth will grow neat after changing teeth.

Japanese "China remnant slaves" have developed the habit of "gnawing at bones" because they lived with China people since childhood, and as a result, they have a pair of neat teeth.

Finally, Professor Raimura used a knife to describe the teeth that had gnawed the bone and the teeth that had not gnawed the bone.

He said that China people have sharp and beautiful teeth because they often chew bones, just like sharpening a knife; Japanese teeth, because they don't chew bones, are like knives rusted in their sheaths, and no matter what the texture is, they can't function.

What is the reason? Generally speaking, the root cause is that Japanese people eat softer food than other countries, which directly leads to Japanese people chewing less.

Insufficient chewing can lead to two problems:

1. Affect the bone formation of the jaw. From a medical point of view, chewing hard objects will cause the gums to be strongly squeezed (for example, some people in China will chew bones when eating meat). This kind of squeezing is a benign stimulus to the gums, which can force the gums to grow fully, and the teeth will grow neat after changing teeth.

Actually, you don't have to chew hard. Like Europeans and Americans, more people like chewing gum.

On the one hand, they think the jaw movement of chewing gum is very sexy, especially for men. On the other hand, they unconsciously exercise their teeth and jaws, making them more developed. It is not easy to squeeze and deform between teeth.

Japanese people, especially women (there is such an aesthetic tendency in East Asia) take a small face as beauty, which is the popular "small face" in film and television circles, and don't want a developed chin. So now Japanese people have smaller chins and crooked teeth.

Perhaps due to the consideration of taste and women's preferences, food processing in Japan is also developing in an increasingly soft direction, such as bread, which is especially soft in Japan.

The number of children with irregular teeth will also increase in Europe and America, because they used to be meat eaters, and now they are becoming more and more vegetarian (environmental protection? ), don't chew bones.

2. Reduce saliva secretion. Chewing is directly proportional to the amount of saliva secreted. As we all know, saliva has bactericidal effect. This is not very important.

After the teeth grow crooked, the brushing effect of the toothbrush is directly reduced, and it can't be brushed in many places, so the tooth decay is also serious, which leads to serious tooth loss in Japan.

This kind of problem brought great trouble to the Japanese during the Second World War. When they selected pilots, more than half of them were eliminated because of uneven teeth. If the teeth are uneven, you can't bite the oxygen mask tightly and you can't be a pilot.

Professor Raimura believes that this congenital defect restricted the quantity and quality of Japanese pilots, so they were defeated by the allied forces in World War II. In modern wars, only by gaining air superiority can we win ground battles. Therefore, Japan was defeated in World War II because the fascist government was opposed by the world and its strategy was wrong, but another important and direct reason was that the Japanese people had uneven teeth.

In fact, it's not just an unsightly problem. Japanese teeth are not good as a whole. Compared with Europe and America, the number of teeth of middle-aged and elderly people in Japan is simply terrible. So there are many dental clinics in Japan, which are very profitable! Going to a dental university in Japan is also the most expensive, taking six years.

Lack of awareness of dental health care

Japanese teeth are not good-looking, but the biggest problem is that the survival rate is not high. Comparing Japan with European and American countries, it will be found that the tooth loss of the elderly in Japan is still serious, because the eating habits and awareness are not in place, and there are not a few people who directly change their dentures. The older the Japanese are, the more dental problems are exposed, and the teeth are irregular, so the number of places that can't be brushed when brushing teeth increases, and the dental health is declining day by day.

Expensive Japanese dental clinic

It is said that the cost of seeing a dentist in Japan is not low. Although there are many dental consultations in Japan, they are generally expensive. It takes six years to study dentistry in Japan, just like all medical students. It takes a lot of effort to train a dentist, so the cost of orthodontics is too high, and many people can't afford to see a dentist regularly. Most people only need to see a dentist when they have a toothache. There are quite a few people with bad key teeth, so there are also many dental consultations in Japan. Many Japanese people say that it is too expensive to accept after seeing a dentist in Japan.

To sum up, the reasons for this phenomenon are as follows:

First, messy teeth are ugly and difficult to keep clean, but many Japanese think young people with messy teeth are cute, so some parents also think that their children don't need to have their teeth corrected. This is a cultural difference.

In Japanese culture, it is a symbol of cuteness to think that girls have tiger teeth. Girls who show their tiger teeth when they smile will be considered lovely and attractive by Japanese boys. Therefore, in Japan, even some girls deliberately make tiger teeth in order to gain the favor of boys.

Second, Japanese food is changing. Before Japan's rapid economic growth, Japanese people seldom ate meat or animal protein. At that time, the staple food was rice, and the vegetables were vegetables, seaweed and tofu. However, Japanese jawbones are relatively large and have a strong bite force. Modern people seldom eat hard food, and as a result, the jawbone is getting smaller and smaller, but the size and number of teeth are the same as before, so the jawbone can't put away the teeth neatly.

If you go to a supermarket in Japan, you will find that Japanese people really have a chance not to eat things with bones. All kinds of meat sold in supermarkets are boneless, and meat like ribs and cartilage is hard to find. Japanese people eat soft food, which leads to the low frequency and intensity of oral chewing, and the teeth and gums are not fully squeezed and rubbed, leading to problems such as poor tooth arrangement and oversized front teeth.

Third, orthodontics in Japan is quite expensive. It may cost 10 to 200,000 yen, which is about 8000- 16000 yuan. Even in severe cases, it may be more expensive. According to different regions, there will be great differences, ranging from 500,000 to 600,000 yen, and even exceeding 6,543.38+0,000 yen.

Why is it so expensive?

Because in Japan, dental treatment for the purpose of treatment is covered by insurance, but if it is for the purpose of cosmetic surgery, you can't enjoy the insurance reimbursement service and need to pay in full. Although many people want to fill their teeth, they have to give up because of economic pressure.

In addition, the correction of teeth is also related to the skull. It is more difficult for Japanese to correct their teeth, because most of them have small maxilla and large plane angle of maxilla, and the bones of orientals are harder than those of westerners. These factors invisibly increase the difficulty of correcting teeth.
