Listerine Tartar Control antiseptic mouthwash fights tartar build up and kills germs that cause bad breath, plaque & gingivitis. Listerine Tartar Control Antiseptic Mouthwash has a fresh Winter Mint flavour, fights tartar formation and reduces the development of plaque and gingivitis over brushing alone. Listerine Tartar Control fights tartar build up by breaking down tartar forming agents - even in the hard to reach places. Tartar is a crusty build up that constantly forms on teeth. It traps stains & harbours germs that attack teeth & gums. Tartar forms when plaque, that has not been removed hardens, & once formed, can only be removed by a dentist. Ever wondered why you need to incorporate mouthwash as part of your oral care routine? Brushing and flossing alone only reaches 25% of your mouth. Incorporating Listerine as your third step helps to kill germs in the remaining 75% of the mouth and can help reduce plaque to help provide that long-lasting fresh breath.Listerine Mouthwash Tartar Control 1 Litre.
