The Waterpik Cordless Advanced Water Flosser provides a unique combination of water pressure and pulsations to clean deep between teeth and below the gumline, removing plaque and debris that traditional brushing and flossing can't reach. It is the first product in its class accepted by the American Dental Association (ADA). The Waterpik Cordless advanced water Flosser is a great solution when you want the convenience of cordless water flossing. Rechargeable, portable, and with an extra quiet design, it's perfect for use in smaller bathrooms or for travel.
