Contains fluoride to help prevent decay, mint to leave your mouth feeling clean and fresh and a wax coating for a smooth easy clean. Use morning and night when brushing to help keep your teeth and gums healthy, to protect against gum disease and tooth decay and to keep your breath fresh. Dentists recommend that flossing should be used as part of your daily dental care regime
