Numerous studies show that Xylitol has powerful benefits for dental health and prevention of tooth decay. Sugar is the perfect source of energy for oral bacteria that are found naturally in the human mouth, such as Streptococcus Mutans. This bacteria causes oral diseases such as plaque and gingivitis. Xylitol does not support the growth of these bacteria, and in fact starves them of their food source, which is sucrose. Leading international regulatory bodies have approved health claims for Xylitol against tooth decay.
