I regret buying this product from himalaya. It is costly than any other toothpaste in the market but it does nothing on teeth whitening. The smell and taste is not that good. You wouldnt able to keep it into mouth for that long as the taste is not good. It claims to remove surface stains on theeth and it contains papain and bromelain, enzymes present in Papaya and Pineapple, which safely whiten teeth. I am using it since a month and seriously it did nothing as claimed.
