No braces is surgery. I made it in Hunan Provincial People's Hospital. Wearing braces. Hunan Provincial People's Hospital has a Hongsheng dental clinic diagonally opposite. There are special corrections. You don't need braces. So is Asiana.
If you wear braces, see if you need to pull out your teeth. I didn't pull out my tooth, but I took it for half a year. If tooth extraction is needed, it will take at least 1 year.
