Best floss I’ve ever used!

I bought this floss, and it’s nothing like the kind with wax on it or the flat “tape” shaped flosses you buy. I like it because it gets thin enough to pass through the sometimes tight contacts between my teeth without all that wax. It makes my teeth feel so much cleaner than the other types of floss.

Benefits

Vegan Sponge Floss™ is clinically proven to remove more plaque than conventional nylon floss - without the irritation. As it glides between your teeth, the woven fibers expand into a soft sponge, adapting to the contours of each tooth for a precise, cushioned cleaning.

Organic coconut oil helps naturally whiten and reduce bacteria, while organic erythritol supports cavity prevention. Thanks to the extra-soft woven texture, this sponge floss helps reduce gum irritation, recession, and bleeding - making it ideal for sensitive gums and tight teeth.

Available in three delicious organic flavors - Clove Cardamom, Peppermint, and Vanilla Mint - each flavor leaves your mouth fresh without artificial sweeteners or dyes.
