1, cultural differences
In many countries, irregular teeth are regarded as "shortcomings", so they will be improved by orthodontics. But in Japan, they dare to regard what people regard as "shortcomings" as beauty and think that tiger teeth are a symbol of cuteness. Some people even have plastic surgery to turn neat teeth into tiger teeth. Japanese aesthetic culture favors exquisite girls who grow up in Kawaii (it's hard to see mainstream Japanese celebrities look sexy). Buckteeth give women a childish feeling, which many Japanese men and women like.
2. Eating habits
Diet is the main reason why Japanese people have ugly teeth. Their main diet is rice, raw fish, tofu and other foods that do not need to be chewed hard. Now Japanese cuisine is developing in a softer and softer direction. Bread made by the Japanese is also very soft. In China, people like to eat hard food (such as gnawing bones) since childhood, which makes their gums fully squeezed, which is a benign stimulus in medicine. In Japan, because the gums are not squeezed enough, the jawbone begins to shrink gradually, resulting in quite irregular teeth.
There is a Japanese orphan who wants to grow up in China and then go back to Japan. His teeth are neater than those of his native. Eating more bones is good for his teeth!
3. The calibration cost is very high
The cost of orthodontics in Japan is very expensive, and it often needs10-200,000 yen, which is about 5,000-10,000 yuan. If it is serious, it will be more expensive, which varies greatly from region to region. It ranges from 500,000 to 600,000 yen, even exceeding 6,543,800 yen. For ordinary people, it is not a small number. In addition, the correction of teeth is also related to the skull. Most Japanese people have relatively small maxilla and large mandibular plane, and the bones of orientals are harder than those of westerners. These factors invisibly increase the difficulty of correcting teeth.
PS: If the teeth are uneven, they can be arranged neatly by wearing an appliance. At present, there are mainly metal brackets, ceramic brackets and popular invisible correction. Which one is suitable depends on your teeth.
