There all on both set of braces. Last frisay I had my top set put on, and they killed for a few days, and then today I had the bottem set put on, so they are gonna kill for a few days, oh joy sad . But when I get them taken off then my teeth will be staight, and I won't have a tooth turned on it side and slanted, some forward some back and some just any way they want to go. my teeth look nasty trust me.
