The new Waterpik® Showerpik® Water Flosser (WP-480) is the easy and effective way to floss for patients who prefer the convenience of conducting their oral care in the shower. The Waterpik® Water Flosser is the only brand clinically proven to be significantly more effective than traditional dental floss for reducing plaque, gingivitis, and gum disease. The Showerpik® unit easily attaches to existing showerheads with a stylish 2-way chrome diverter that allows for shower only or shower plus water flosser. It includes a convenient rechargeable battery pack, two Classic Jet Tips and a hygienic tip cover, and because it's attached to the shower, the Showerpik provides an unlimited source of water, eliminating the need to refill a water reservoir.
