Braces depend on the appearance of your teeth. Even if you want to change your chin, even if your teeth are good, the doctor will not necessarily put braces on you. I am wearing braces now. If your teeth are good, give up wearing braces and change your chin early. After wearing braces, eating porridge and liquid food for the first week will make you miserable and occasionally hurt your lips. Moreover, after wearing braces, your face will become very big and ugly, so you can't cry. I used to look fine, but my teeth were bad. Now I'm wearing braces and I'm so ugly that I can hardly look in the mirror.
