This toothpaste has stain prevention shield for long lasting whitening and the low abrasion helps maintain enamel. Baking soda help rub away plaque, tartar, and surface stains from your teeth, providing you with a brighter smile. Baking soda is good for teeth whitening because it is a very mild abrasive, which helps remove stains from the surface of your teeth. In addition, baking soda is alkaline and salty, which helps lighten acid-based food stains - such as those from coffee, tea, and red wine - on teeth. Toothpastes containing baking soda have been shown to have antibacterial properties, which can help protect your teeth from decay. Fluoride helps promote remineralization of the tooth surface. Fluoride ions are taken up into the enamel and form fluorapatite which is harder than hydroxyapatite. Thus, fluoride strengthens the enamel which is then more resistant to acid attacks and the incidence of dental caries is reduced. Sodium fluoride in toothpaste and mouthwash safely and effectively helps to prevent tooth decay, when formulated correctly and used as directed. This toothpaste has fresh mint flavor that makes your mouth feel colder and leaves a fresh sensation.
