Patanjali dant kanti is a good product. This is clean the teeths and improve the shinness of teeths after consecutive use for few weeks. The flavor isnt that good as this tooth past is made by the humbles.
This product also helps to improve teeth conditions. Its helps to improve the sensevity issue and all other issues.
I had a sensevity issue for that issue I use sensevity toothpaste which costs some where around rs. 100 but Patanjali dant kanti just for rs. 30 and gives the same results.
Overall this is a good product to use.
