If you don't know anyone, you can go to the stomatological hospital to calculate. The quality is guaranteed and the price is not much cheaper. I was 15 years old when I did it. 5500, and then you have to pay the registration fee of 10 every time you go. There were many people later. If I'm unlucky, I have to wait for a few hours. I think there are more people now. You said 9000.
You are 2 1 year old. Using a corrector won't be particularly effective ..... because the root of the tooth is almost fixed. You should think it over. It will hurt a little at first.
