This fluoride-free toothpaste helps reduce plaque and prevent tartar buildup with regular brushing. It also 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. We've also added natural flavouring 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.
