I am using patanjali dant kanti since 2016 and never had any problem. I purchased the patanjali from departmental store in my locality It keep all patanjali products along with other brands.
The first time when I squeezed the dant kanti tube to put the paste on mybrush I just surprise as I have never seen brown toothpaste before. Yes patanjali dant kanti toothpatse is brown in color therefor, the foam appears whitish brown after brushing
I am using this paste a day. It give more of clove smell and taste than the other ingredients in the toothpaste
