Xylitol is a naturally occurring carbohydrate, commercially derived from corncobs or hardwood trees. Xylitol also occurs naturally in our bodies- an average size adult manufactures up to 15 grams of xylitol daily. Pure xylitol is a white crystalline substance that looks and tastes like sugar. Consistently using small amounts of xylitol stimulates saliva flow and increases saliva’s buffering capacity and protective factors. Xylitol’s antimicrobial properties help prevent tooth decay by inhibiting bacteria and plaque from sticking to the teeth.
