Cocofloss is the #1 dentist-recommended woven floss.* Featuring 500+ woven, expandable fibers coated in gum-loving coconut oil, it scrubs away plaque and gunk for a “just-left-the-dentist” fresh feeling. Your toothbrush can't reach 35% of your teeth's surfaces — mostly between your teeth. Because floss is vital to your oral care over a lifetime, choose a floss that's healthy for your smile, healthy for the planet, and proven to work.
