SMILE WITH CONFIDENCE: Pay attention to your oral hygiene. It might be that you avoid smiling because you don’t really like your smile. Maybe you have bad breath, or your teeth are yellowish, and all you really want to do is hide this. However, this is a confidence killer and it’s something you should work on. What you can do at home is make sure you brush your teeth and floss them regularly, and that you use fluoride toothpaste to improve your oral health. When your teeth are healthy and look nice, you’ll feel more confident about smiling and will do it more freely.
