The BreathRx dual action rinse formula eliminates oral malodor in two phases. First, its powerful active ingredient prevents the formation of 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 Volatile Sulfur Compounds (VSCs). Nothing leaves your breath fresher for longer. Plus it is 100% alcohol-free, so it has none of the harmful and mouth-drying effects of alcohol.
