I am using Patanjali Dant Kanti tooth paste since last six months and I am feeling excellent for my teeth. It cleans mouth and teeth in very effective manner. After using this product I forget to use other branded tooth paste. It really works for freshen our mouth twenty four hours. It removes stains from the teeth and brightens it surprisingly. Its taste is slightly bitter but bearable. It also works for removing mouth smell for long time. Its cost is also very reasonable with comparison of it quality. Its simple variant(Dant Kanti) is also useful likely. So, I strongly recommend this product to use without any doubt.
