Helps prevent tooth decay. Helps reduce bacteria that are harmful to teeth. Helps inhibit the adhesion of bacteria on the tooth surface. Consumption of carbohydrates and sugar in the mouth contains bacteria (Streptococcus mutans) lives. The bacteria uses sugar as food to grow and produce acid. The acid that is created destroys tooth enamel. which causes tooth decay, inhibiting tooth decay with xylitol, xylitol Stops the activity of bacteria (Streptococcus mutans) and can reduce plaque. When bacteria are exposed to xylitol Bacteria cannot digest xylitol as food. Therefore unable to create acid, it will weaken to the point that it cannot Can harm teeth.
