NOW Foods XyliWhite Platinum Mint Toothpaste Gel with Baking Soda is a fluoride-free natural toothpaste powered by xylitol — a birch-derived sugar alcohol that actively inhibits Streptococcus mutans, the primary bacteria responsible for tooth decay. Unlike sugar, xylitol cannot be metabolized by oral bacteria, starving decay-causing microbes while simultaneously stimulating saliva production and raising oral pH to create an environment where remineralization can occur. Baking soda provides gentle, non-abrasive whitening and helps neutralize the acids that erode enamel. XyliWhite is free from fluoride, SLS (sodium lauryl sulfate), artificial flavors, and harsh abrasives — making it an excellent choice for those seeking a clean, effective natural alternative to conventional toothpaste. The refreshing platinum mint flavor provides a clean, fresh-breath finish.
