XYLTF--- Xylitol is a dentist’s dream. It reverses all these destructive effects of sugar on oral health. Xylitol is non-fermentable and therefore cannot be converted to acids by oral bacteria, thus it helps to restore a proper alkaline/acid balance in the mouth. This alkaline environment is inhospitable to all the destructive bacteria, especially the worst variety, Streptococcus mutans. It also inhibits plaque formation.
