When the protective layer of teeth (enamel) is worn away or gums recede the dentine underneath becomes exposed. When the exposed dentine comes in contact with hot cold sweet or sour food and drinks it can trigger a sharp short sensation called tooth sensitivity. Sensodyne Deep Clean is a daily fluoride toothpaste that helps protect against tooth sensitivity while still providing the benefits of a regular paste like strong teeth and health gums. This toothpaste is powered with foam boost technology and brushing with this toothpaste not only leaves you with a lasting cooling sensation but also gives your teeth the deep clean they deserve. With twice daily brushing you can enjoy your favorite foods and drinks without the worry of sensitive teeth. Sensodyne Deep Clean tooth paste is available in a 70 gm pack. Always follow instructions and guidance included on the pack before use.
