Well I have really bad morning breath so i brush my teeth and use mouthwash, but how do i keep my breath fresh after something like lunch during school? I don't want to deal with mints. i brush my teeth twice a day. What else can I do? I'm trying to impress a boy in my class. Also, something that will make my teeth white and sparkly?

P.S. I have braces, so no whitening strips.
