Aquafresh Whitening plus Tartar Protection Toothpaste with Triclene is a patented formulation that helps to safely whiten teeth without bleach or peroxide as it fights cavities, plaque, and tartar and it's as gentle as regular toothpaste on tooth enamel. Stains consist of proteins, calcium and carbohydrates. Aquafresh's patented Triclene formula gently removes stains without bleach or peroxide to get teeth whiter. Helps prevent tarter build-up above the gumline. Freshens breath. Aquafresh Whitening Toothpaste with Tartar Protection has been found to be a safe and effective decay-preventive dentifrice that can be of significant value when used as directed in a conscientiously applied program of oral hygiene and regular professional care. It has been shown to whiten teeth by removing surface stains. It has been shown to reduce the formation of tartar above the gumline, but has not been shown to have a therapeutic benefit on periodontal disease. This product contains no sugar, like all ADA-accepted toothpastes.
