Without saying a word, your mouth is sending messages to everyone you meet. People often make snap judgments about individuals based solely on their smile. A smile says a lot about your personality and having beautiful straight teeth will affect the way you feel as well as look, it will increase your self-confidence, and because a smile is contagious, people will respond to you better. Once your teeth are straight and you can bite together correctly, you can eat more comfortably and clean your teeth more easily. Most importantly though, you will never lose an opportunity to smile!
