I am using Glister toothpaste for a year now, it is habit forming . I was pushed by one of my friend who pushed the product as he is amway distributor.He claimed that it will give teeth whitening and remove stains of tobacco and smoking, also it will help preventing cavity.Unfortunately nothing happened and I am feeling cheated paying a high price of Rs 150 , month on month.Problem is its habit forming so its difficult to stop using. But I will stop it as it has chemicals for whitening which is effecting the enamel. I strongly recommend not to use this paste.Rather I am shifting to Dantkanti from Patanjali. I trust them. Thanks
