The exclusive BreathRx dual-action rinse formula eliminates oral malodor in two phases. First, its powerful active ingredient prevents plaque that leads to gingivitis, and the formation of Volatile Sulfur Compounds (VSCs) – the primary cause of bad breath. Second, the Zinc keeps working throughout the day to neutralize VSCs. Nothing leaves your breath fresher longer. Plus, it's 100% alcohol-free, so it has none of the harmful and mouth-drying effects of alcohol.
