Choose your floss.
Break off about 18 inches of the floss and wrap most of it around your index fingers, leaving about 4 inches between your hands.
Looking in your mirror to see what you are doing, move the floss gently back and forth guiding it between two teeth.
Curve the floss around one of the teeth and once the floss hits the gum line, gently move it back and forth cleaning the crevice between your tooth and gum.
Carefully slide the floss up under the gum and scrape down on the side of the tooth.
Curve the floss around the other tooth. Gently move it back and forth and carefully slide it up under the gum and scrape down the side of that tooth.
Move to an adjacent space to clean, changing the area of the dental floss you are using.
Continue to floss until you have cleaned between all of your teeth.
Rinse with mouthwash or water.
