1.) Wind 18" of floss around middle fingers of each hand. Pinch floss between thumbs and index fingers, leaving a 1"- 2" length in between. Use thumbs to direct floss between upper teeth.
2.) Keep a 1" - 2" length of floss taut between fingers. Use index fingers to guide floss between contacts of the lower teeth.
3.) Gently guide floss between the teeth by using a zigzag motion. DO NOT SNAP FLOSS BETWEEN YOUR TEETH. Contour floss around the side of the tooth.
4.) Slide floss up and down against the tooth surface and under the gumline. Floss each tooth thoroughly with a clean section of floss.
