Easy glide and gentle action. Small round shape for close-contact teeth. Strong and durable. ADA accepted. The ADA Council on Scientific Affairs' acceptance of Tom's of Maine Naturally Waxed Antiplaque Round Floss is based on its finding that the product is effective for removing plaque between teeth and helping to prevent or reduce gingivitis, when used as directed. Plaque-removing action made gentle and smooth by three natural waxes. Flossing removes plaque and particles - which can lead to tooth decay and gum disease - from places between teeth that brushing can't reach. Our Naturally Waxed Antiplaque Round Floss is made of many strong nylon filaments woven together to prevent snapping or fraying and prepared with a unique combination of natural waxes. It glides smoothly between teeth and is gentle on gums, and its small round shape lets you get between close-contact teeth. Please let us know what you think! No synthetic waxes or artificial sweeteners, preservatives, colors, or flavors. No animal testing. Naturally, it works.
