Well ~ ~ ~ I made that thing, which was very expensive. I went to a big hospital and had a check-up once a month. More than 30 thousand in three years If I don't go to the clinic, I'd better pull out some teeth for you, but I didn't get them done in the end. At that time, you didn't even cry If you can't afford it, you'd better not do it.
Finally, it's very hard to make that thing, and you may have to pull out your teeth (four are fatal). After the examination, you can't eat hard food at all, and your teeth are sour and soft. Finally, you must wear false teeth to shape them. It takes 3-4 years to go back and forth.
