This natural Dr. Tung's Smart Floss has the amazing ability to instantly adapt to the unique contours of your teeth. The floss stretches and expands, creating a larger surface area to better remove plaque and food particles. In fact, this smart dental floss is clinically proven to remove up to 55% more plaque than other common floss types. Smart Floss is also much gentler on gums — and your fingers. Now that's something to smile about!

What is Dr. Tung's Smart Floss made of, and how does it to expand?

Dr. Tung's Smart Floss is made of multifilament polyester fibers using a proprietary, patented process that allows the floss to expand. The fibers are lightly coated with a vegetable/beeswax blend (contains beeswax plus one or more of candelilla, carnauba, castor oil and rice bran wax). The floss is flavored with natural cardamom essential oils.

Is Dr. Tung's Smart Floss eco-friendly?

Yes, Dr. Tung's Smart Floss is eco-friendly and effective. The international award-winning packaging is entirely PLASTIC-FREE and made of FSC-certified paperboard. The flavor of the floss itself is protected in an inner sachet made from renewable wood-pulp.

Cardamom essential oil, proprietary vegetable/beeswax blend (contains beeswax plus one or more of candelila, carnauba, castor oil and rice bran wax), multi-filament polyester fiber.

Wrap 18" of floss around fingers and draw tight. Tug and release - it expands! Slide floss between teeth, curve it around teeth and clean between tooth and gum with gentle up and down motion.
