I have used many brands in the past(pepsodent, closeup, colgate, anchor etc.).and settled on sensodyne as I found it to be most gentle and effective for my teeth amongst these.
But I tried Patanjali Dant Kanti this time and I am more than delighted.
The best part is that it is ayurvedic and by an indian brand! So go for it and give it a try.
I was a little worried, since I have sensitive teeth and was on medication. Dant Kanti made me forget all the discomfort. Really, a wonderful help.
