Benefits

RADIUS Vegan Sponge Floss is clinically proven to remove more plaque than conventional tape floss. As you floss, the woven fibers expand into a sponge-like texture that conforms to each tooth, increasing surface contact to help lift plaque and debris more effectively than traditional flat floss. The result is a deeper clean with less pressure, making it an ideal choice for sensitive gums and tight spaces between teeth. 

Available in three delicious flavors—Clove Cardamom, Peppermint, and Vanilla Mint—each leaves your mouth feeling fresh without artificial sweeteners, dyes, or unnecessary additives.
