Dr. Tung's Smart Floss - 30 Yards / 27 m Dr. Tungs Smart Floss with New Biodegradable Dispenser! There's no other floss quite like Dr.Tung's Smart Floss. It stretches and expands into interdental spaces for better removal of plaque and food particles. This high-performance floss is suitable for everyone - people with tight spaces, wider spaces... even braces. This revolutionary floss is also great for gums. You see, Smart Floss dental floss is gentler on gums because it is cushion-soft and can stretch. Unlike those other flosses with no spring that can often hurt gums... and fingers! Smart Floss dental floss is clinically proven to be more effective than regular floss. It has been shown to remove up to 40% more plaque than some of the most popular flosses, i.e. regular waxed and unwaxed flosses and PTFE monofilament floss (compare to Glide). Even electric or manual flossers which claim to be as effective as regular floss are no match for Smart Floss. Smart Floss can clean around the teeth and reach deeper into the interdental spaces, leaving teeth cleaner and you smiling longer! Now there's no excuse to use a less effective floss.
