The Waterpik WF-05 provides both clean teeth and a whiter smile. In addition to obtaining healthier gums with this electric flosser, you can also whiten the space between your teeth with the included whitening tablets. The only thing you have to do is place a tablet in the electric flosser. 4 nozzles are included, 2 of which have a jet head. This is the most common nozzle and is mainly used for regular, adult teeth. You'll also receive an ortho head, made for teeth with braces or splints. Finally, you'll receive a dental plaque head. Use this when your teeth mainly consist of implants, bridges, crowns, and other artificial solutions. The brush attachments can be neatly stored after flossing.
