Additional Details ------------------------------ Directions: To use this dental floss, take approximately 18 inches of floss and wrap it around your middle fingers, leaving about 2 inches between your hands. Use your thumbs and index fingers to gently guide the floss between your teeth, curving it against the tooth surface as you go. Move the floss up and down against the side of each tooth, taking care to avoid snapping or forcing it. Repeat this process for all of your teeth, including the backs of your molars.
