Sensodyne Rapid Relief Toothpaste is a daily fluoride toothpaste that acts rapidly against tooth sensitivity, while still providing the benefits of regular paste-like strong teeth and healthy gums. It starts to act rapidly by building a mineral-like layer over exposed dentine and within microscopic channels. The paste also builds ongoing protection with every brush so that you can enjoy your favourite foods and drinks without the worry of sensitive teeth. Brushing twice a day provides protection from tooth sensitivity.
