Buy 3, get 2 free. Helps Maintain White Teeth. Target gunk in the mouth. Freshen breath at the source. iD Stain Whitening Mouthwash targets the gunk your toothbrush left behind and pulls it into visible clumps you can actually see in the sink. Powered by hydrogen peroxide and essential oil actives, iD Stain helps maintain whiter teeth and leaves your mouth feeling seriously fresh from the first rinse. iD Stain is not your average mouthwash. This oral rinse works with your routine to help maintain white teeth, freshen breath, and lift build-up from the areas brushing can miss. As you rinse, the formula interacts with oral debris, pulling them into visible particles you can actually see in the sink. That’s what your toothbrush didn’t catch. Use as directed as part of your daily oral care routine. Visible residue is not guaranteed and depends on individual factors. Results may vary between individuals.
