My previous teeth were ugly, none of them were neat, and then I corrected them with braces 1.5 years. At that time, when I was young, it was easier to correct it. It usually lasts about 2 years, and then you can take it off. I will make my teeth beautiful, but the whole period is actually quite painful, but there is nothing I can do to make them beautiful. I like my teeth very much. They are very neat.
