I brush my teeth twice a day, floss occasionally and use mouthwash semi-regularly. I've never had a cavity and my teeth are perfectly straight. People look at my nerdy features and ask if I used to wear braces because my teeth are that well-formed.

Now the bad news. My teeth are beginning to yellow. Not a big deal these days with whitening procedures, but it's not something I'm particularly proud of. I drink a lot of coffee and soft drinks and I smoke as well.
