Designed for use with the Waterpik Whitening Water Flosser, these Waterpik Whitening Tablets help deliver precision teeth whitening when used with your water flosser. Use one tablet daily to remove stains from hard-to-reach areas such as between teeth and at the gum line that other products miss. These tablets are clinically proven to remove an additional 25% more stains than brushing alone. The refreshing mint flavor leaves your mouth feeling fresh and clean.
