Brushing alone is not enough! The Waterpik Water Flosser provides a unique combination of water pressure and pulsations to clean deep between teeth and below the gumline, removing harmful bacteria 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. The Cordless Advanced includes 3 pressure settings allowing you to personalize your water pressure intensity. The Cordless Advanced has a 4 hour rapid charge and an easy-to-fill reservoir. Waterpik Water Flossers are clinically proven to be more effective than traditional dental floss and it's perfect for anyone with braces or implants, and those with crowns, bridges, and veneers.
