Shred resistant waxed dental floss. Cleans where your brush can't reach. Brushing alone can't get to all the hard-to-reach places where plaque builds up. But Oral-B EssentialFloss can. With its light wax coating and its shred resistant texture, it slides easily between your teeth and below the gumline. It helps clean the tough-to-get plaque away. Used morning or evening when you brush. EssentialFloss helps your gums and your teeth stay healthy.
