It’s not enough to just brush your teeth. It’s important to floss at least once per day. Flossing dislodges food that’s stuck between teeth, and it also cleans plaque and bacteria from your tooth surfaces. If not removed, that plaque and bacteria will generate acids that wear down enamel and lead to decay.
Watch this informative video from the American Dental Association to learn about the importance of flossing and to see a demonstration of correct technique.
