This fluoride free toothpaste whitens your teeth by removing surface stains and uses authentic naturally derived ingredients. Our zinc citrate is sourced from zinc, a naturally occurring mineral and xylitol, a natural ingredient derived from birch trees or corn. Our toothpaste helps to reduce plaque with regular brushing, and we've also added natural flavoring for a taste that will make you look forward to brushing. We produce this toothpaste without fluoride because we respect our customers' diverse needs and interests.
