Sensodyne Sensitivity & Gum toothpaste is clinically proven to relieve tooth sensitivity & improve gum health with twice daily brushing. Its 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.
