For implants, crowns, bridges, and other restorations. Clinically proven more effective than string floss for improving gum health, the new Plaque Seeker™ Tip is designed to provide the benefits of pulsating water. It has three thin tufts of bristles to access stubborn plaque around implants, crowns, bridges, veneers, and other areas that are especially susceptible to plaque accumulation. Change every 3 months. For use with the Waterpik® Ultra Water Flosser WP-100 and Cordless Plus Water Flosser WP-450.
