1. Take an 18-inch piece of floww and tightly hold 1-2 inches between your thumbs and index fingers.
2. Gently guide the floss between your teeth with a back and forth motion. When the floss reaches the gum line, curve it into a C shape against one tooth.
3. Gently rub the side of the tooth, moving the floss away from the gum with up and down motions until clean. Then do the opposite tooth. Repeat for all teeth.
