Glister is not only a paste it’s a total solution for oral care. My whole family use it for last 15 years. Its effectiveness is so vast that can not be describe in words. It clear the teeth, whiten the teeth, It strong the gum, remineralize the teeth. It’s smoothness is best due to this it only clean the teeth not the enamel. One tube for whole family doing two time brush runs for 3-4 months. now it is available in 190gm tube and it takes 6-8 months. So many people give some negative comment on this paste but I will be using it continuously .Definitely if any one asked for paste I recomend this paste .Our all guest who ones comes to our home and use this paste then next they are became the user of Glister. Thanks to Amway to produce such an amazing oral care product.
