Sister (or brother), when I was your age, I wanted to do it, but I wouldn't let it at home for the same reason as you. It's no use arguing and fighting. But when I grew up, I did use the money I earned to get my teeth removed. Later, a dentist I trusted told me about many bad consequences of orthodontics. For example, when I was 40 years old, my teeth were loose, and I was advised not to get them unless I was ugly. I can't say anything else.

If you really want to have your teeth pulled out, you can fight for it (for example, if you get any results in the exam, you can pull my teeth out, and so on). ). If you can't get it, you can secretly save money yourself (in fact, there is not much money, and it is less than a month's salary when you grow up). It's not too late to leave your parents and go to college. Don't quarrel with your family because of this kind of thing. It's meaningless and unnecessary (maybe I'm nine years older than you, and I'm a little bitter, O(∩_∩)O haha ~, you'll understand me when you grow up and leave home)
