For Healthy Teeth and Gums: Brush with a fluoride toothpaste twice a day, or as recommended by a dentist. Use dental floss daily. Have regular dental check-ups. Baking soda & peroxide are kept separate and fresh. The ingredients combine to create active powerful oxygen bubbles. Bubbling action formula breaks down stains and leaves teeth noticeably whiter. Advanced Whitening Formula: Begins to whiten teeth immediately for visible results in as little as two weeks. Helps prevent cavities. Removes plaque with proper brushing. Helps stop new tartar build-up before it forms. Freshens breath. Easy to use refill. When your Mentadent pump is empty, simply remove the empty cartridge and insert the refill.
