refinery29 For the third installment of our smile-centric series with @opticwhite, we talked to model Megan about what her killer gap-toothed grin means to her. #ad "My smile means that it's totally okay to be different and to embrace the things that make you unique. Growing up, I was the only kid who didn't get braces and, at the time, I wanted to be like everyone else. But today at 26, I wouldn't want anyone's smile but mine."
