Sensodyne Sensitivity & Gum Whitening toothpaste is a dual action toothpaste that's specifically designed to help people who have both sensitivity and early gum problems. Common triggers can include cold drinks or food, hot drinks or food. With its low abrasion formula, Sensodyne Sensitivity & Gum Whitening is formulated to relieve tooth sensitivity and improve gum health at the same time. Sensodyne sensitivity and gum toothpaste builds a protective layer over sensitive areas of the teeth, while targeting and removing plaque bacteria to help reduce swollen, bleeding gums. Plus, it works to lift stains and gently whiten teeth over time. You can take control of both sensitivity and early gum problems with one specialized toothpaste for sensitive teeth while whitening at the same time.
