I am using patanjali dant kanti since 3 years it is the best tooth paste I have used till date the best thing about patanjali dant kanti is it is hundred percent natural product made by most trusted brand patanjali. each patanjali product goes through many quality chech before coming to market. another good factor of patanjali dant kanti is it made by an indian company. it is best then many forein countary tooth past like colgate. I would recomend every one to use this product as it is aurvadic.
