It is important to make a habit of brushing your teeth. I know some people who don't brush their teeth everyday, believe it or not. It is good for your health to brush your teeth, and it can add up to ten years to your lifespan. It reduces the chance of you experiencing pain and disease in your life as well. Remember to use a toothbrush, toothpaste, and mouthwash that is approved by the American Dental Association, also known as the ADA.
