Often tooth sensitivity and gum problems go hand in hand. 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. Meanwhile Gum problems are caused by a build-up of plaque bacteria. Sensodyne Sensitivity & Gum is a daily fluoride toothpaste that helps protect against tooth sensitivity and improves gum health while still providing the benefits of a regular paste. This toothpaste has a low abrasion dual action formula. It protects the teeth against sensitivity and helps target & remove plaque bacterial for healthy gums. With twice daily brushing you can enjoy your favorite foods and drinks without the worry of sensitive teeth. Sensodyne Sensitivity & Gum tooth paste is available in two packs - 70 gm and 140 gm (70 gm * 2) combo pack. Always follow instructions and guidance included on the pack before use.
