Benefits

RADIUS Vegan Sponge Floss is clinically proven to remove more plaque than conventional tape 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.
