Lil Drug Waxed Dental Floss brushing alone can not 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, Essential floss helps your gums and your teeth stay healthy.
