Step 1
Take a piece of floss and wrap it around your middle fingers, leaving about 2 inches between the hands. Use your index fingers to guide the floss between the teeth.
Step 2
Slide the floss between the teeth and wrap it into a "C" shape. It should wrap around the base of the tooth, where the tooth meets the gum.
Step 3
Wipe the tooth from bottom to top 2 or 3 times or more, until it is clean. Be sure you floss both sides of each tooth, and don't forget the backs of the last molars. Move to a new part of the floss as you move from tooth to tooth.
