Since my childhood I used to use Colgate tooth paste as that time there was not any reputed brand. But, recently when I bought Patanjali Dant Kanti the entire scene changed. The next morning when I used it, I really feel fresh and the flavor which I thought would not be good, actually was good and I felt fresh atleast 3-4 hours. Other brands claims 12 hours or more freshness which is totally wrong. Dant Kanti is actually a product which must be used by people, this is totally awesome and the ingredients are also natural and effective. I do refer my friends to use and get benefitted because it is really a all-rounder tooth paste for our teeth.
