Yes! Xylitol, the base ingredient of our mints, is sugar-free and actually improves dental health. Xylitol inhibits the growth of the bacteria that cause cavities. Streptococcus mutans, the bacteria that causes cavities, cannot use xylitol to grow. With frequent Xylitol use, the quality of the bacteria in the mouth changes and fewer decay-causing bacteria survive. We derive ours from birch trees and use it as a natural sweetener.
