I don't know how to smile with it yet. It took me about a week and a half to get used to it. I was really really painful at first, but a week later it wasn't that much anymore. I kind of have a different bracket compared to my other friends. They have this kind of "H" bracket, but mine was a loner and was an "I". I don't like the brackets coz it looks like my old retainers! With the same color! :\ But I have to live with it, for at least a year.
