Sensodyne Daily Care toothpastes has been specially formulated for people with sensitive teeth and can be used every day. It provides all the benefits of regular toothpaste, while providing expert care for sensitive teeth. Brush twice a day every day to help strengthen teeth, fight tooth decay and promote gum health. Sensitivity starts with exposed dentine. When enamel is worn away or gums recede, the dentine underneath becomes exposed. Dentine is softer than enamel, making teeth with exposed dentine more vulnerable to future problems.
