Sensodyne Daily Care + Whitening toothpaste is specially formulated to relieve sensitivity. When enamel is worn away or gums recede, the dentine underneath becomes exposed. This can lead to sensitivity pain, for example, with cold and hot drinks. Sensodyne Daily Care Toothpaste + Whitening works inside the tooth to help calm the nerves for 24/7 sensitivity protection*, while containing fluoride to strengthen teeth and healthy gums, with twice daily brushing. Leaves your mouth feeling clean and fresh and gently restores the natural whiteness of your teeth. *With twice daily brushing
