At Tom's of Maine that means we use authentic natural ingredients. We use zinc citrate sourced from zinc - a naturally occurring mineral and xylitol, a natural ingredient derived from birch trees or corn. Plus, natural flavoring for a taste that will make you look forward to brushing! Fluoride-free formula: Some people do not want fluoride in their toothpaste. We produce this toothpaste without fluoride because we respect our customers' diverse needs and interests.
