NOW Foods XyliWhite Neem & Tea Tree Toothpaste Gel harnesses two of the most potent natural antimicrobial botanicals — neem and tea tree oil — alongside xylitol to provide a comprehensive, fluoride-free natural oral care formula. Neem has been used in Ayurvedic dental care for thousands of years for its powerful antibacterial properties against the oral pathogens responsible for gum disease and tooth decay. Tea tree oil (terpinen-4-ol) provides complementary antimicrobial activity against Streptococcus mutans and other oral bacteria. Xylitol actively starves decay-causing bacteria by providing a non-fermentable sugar substitute. Free from fluoride, SLS (sodium lauryl sulfate), artificial flavors, and synthetic preservatives. A powerful natural toothpaste for those who want to maintain oral health with botanical ingredients rather than synthetic chemicals.
