Our alcohol-free fluoride mouthwash provides additional cavity protection for those who wish to supplement their daily dental regimen. Xylitol, a cool, flavorful natural ingredient from birch trees, helps soothe a dry mouth, and naturally-sourced fluoride helps prevent cavities. We've also added the antioxidant green tea as well as aloe vera leaf juice and chamomile for a soothing feel. Strong mint flavors may make rinsing uncomfortable for those with a dry mouth, so Tom?s uses a gentle lemon-lime flavor to make your mouth feel clean and cool and your breath feel fresh.
