SInce 2-3 month I am using Dant Kanti paste every morning to clean my teeth.
It is amazing and if you are getting pain in your teeth, cold hot things are upsetting you then immediately go for it.
Nowadays, it is not difficult to find it, you can find it anywhere even in all stores.
Moreover, I have noticed the prices with their competitors it will surprise you too. A small paste pack which cost you less than 40/- from patanjali but in the same grams you will find it in Rs 54/- i.e colgate, closeup and etc.
So you can see it. A Consumer is KING so at least you should try it once.
