All floss is not created equal! Eco-Dent floss is not only the most economical floss, but it has real benefits, such as being vegan waxed, and made with a blend of natural essential oils and enzymes to reduce plaque and help you maintain healthy teeth and gums. Eco-Dent packages their floss in a cardboard carton rather than a plastic case to cut down on ecological damage done by plastic and the disposal of plastic. Good for you, good for the environment.
