Enjoy our Advanced Whitening System which features a pre rinse that better helps prepare your teeth for this optimal whitening treatment. Included in this system is also our Plus White 5 Minute Speed Whitening Gel, our Comfort Fit application mouth tray, and StainGuard Post Rinse. Our whitening gel starts whitening your teeth in just 5 minutes, by taking advantage of the same powerful ingredient dentists use to professionally whiten and brighten teeth. Unlike the dentist, you can achieve a brilliant smile at a fraction of the cost. Plus White works by gently lifting away stains, eliminating yellowing, and dramatically whitening teeth. This kit does provide you with our Comfort Fit Mouth Tray, which covers both bottom and top teeth, for even and complete coverage whitening. Bleaching begins working with 5 minutes of your very first application! You'll see whiter and brighter teeth within days. Finish up with the Plus White StainGuard Post Rinse, to lock in whiteness and help delay stains from re-appearing on your teeth. As the makers of the very first whitening toothpaste, Plus White has been an industry leader in creating dream smiles for over 25 years. Our whole Plus White line is designed to help you achieve maximum whitening results quickly, easily, and all from home. With Plus White, Love Your Smile. See packaging for directions. Recommended usage of Whitening Gel is twice daily for 2 weeks followed by 1-2 times a week for maintenance. A whiter, brighter smile awaits!
