How much does it cost to wear braces in Japan?

When you come to Japan, you must first join the national health insurance. In this case, no matter what disease you see, only 30% of the medical expenses are paid. Much cheaper. It takes time to see a dentist in Japan. It usually takes about a month to wear braces. He won't fix it for you right away. He will grind your teeth today and press your teeth next week. So pay hundreds or thousands of yen at a time. It adds up to two. Let's say thirty thousand yen. And some teeth have to pay for themselves, but they can't use medical insurance. After my worm tooth is pulled out, give me a false tooth. Do you want plastic or good quality ceramic? What I want is 80 thousand yen. About RMB 4000.
