A heavenly addition to any oral care routine. What makes the Dual Chamber Oxyburst Mouthwash so effective? Most whitening mouthwashes lose their potency while they sit on the shelf. These dual-solution components are housed in separate chambers, activated only when you use them. Mixed together, they create pH-balanced Oxyburst bubbles which gently remove teeth stains, create fresh breath, and helps maintain strong teeth and healthy gums. No other mouthwash whitens teeth better or faster.
