Try to keep the floss taut between the fingers.
Dental floss comes in many varieties (waxed, unwaxed, flavored, tape) and may be chosen based on personal preference.
Gently guide the floss between the teeth by using a zig-zag motion.
Contour the floss around the side of each tooth.
Slide the dental floss up and down against the tooth surface and under the gum line.
