Take about 18 inches (50cm) of floss and loosely wrap most of it around each middle finger (wrapping more around one finger than the other) leaving 2 inches (5cm) of floss in between.With your thumbs and index fingers holding the floss taut, gently slide it down between your teeth, while being careful not to snap it down on your gums.Curve the floss around each tooth in a "C" shape and gently move it up and down the sides of each tooth, including under the gumline.Unroll a new section of floss as you move from tooth to tooth. At first, flossing might feel awkward. But stick with it! With just a little patience and practice, it will begin to feel as natural as brushing your teeth.
