Contains fluoride for cavity prevention and calcium for clean teeth. Dear friends, When we founded Tom's of Maine in 1970, we based it on the idea that nature has answers to our everyday needs. What makes our products so effective? We use natural ingredients in innovative ways without adding any artificial flavors, fragrances, colors, or preservatives. Our toothpaste, mouthwash, soap and deodorant products have proven our original belief: ingredients from nature really work. Please let us know what you think! Kate & Tom Chappell. Naturally, it works. The ADA Council of Scientific Affairs acceptance of Tom's of Maine Natural Anticavity Fluoride Toothpaste is based on its finding that the product is effective in helping to prevent and reduce tooth decay, when used as directed. Fluoride helps prevent cavities. Fluoride helps remineralize soft spots on teeth before they turn into full-fledged cavities and strengthens the tooth structure so enamel becomes more resistant to decay. This product does not contain saccharin; artificial sweeteners, preservatives, colors, or flavors; or animal ingredients. Tom's of Maine products are tested for safety without the uses of animals. Made in U.S.A.
