10 Top-Rated Waterpiks You'll Wish You Bought Sooner

Waterpik Whitening Water Flosser ($100, originally $120)

This genius device has all the benefits of a traditional water flosser, but it comes with whitening tablets that you place into a special infuser located in the flosser's handle. "When I started using the whitening tabs, it really made a huge difference," writes a reviewer. "I've tried whitening strips and other products and this hands down has done the best job at whitening my teeth after only a week."
