Sensodyne Sensitivity & Gum Whitening toothpaste is clinically proven to relieve tooth sensitivity & improve gum health with twice daily brushing. It’s dual action formula works in two ways. It builds a protective layer over the exposed sensitive areas of your teeth, to help relieve sensitivity whilst the NEW Micro foam formula targets and removes plaque bacteria, penetrating even the hard-to-reach areas in between teeth and along the gumline, to help restore gum health. With twice daily brushing, it also effectively removes stains to help restore the natural whiteness of your teeth.
