This toothpaste is really nice and I have been using the same from paste some time I prefer between 3-4 brands among which this is also onr of them.
Though this might be little expensive but yes you can try to uae it and the result is you will be satisfied I dnt know weather they are certified by indian dental assocation or not but yes toothpaste is good.
One can give a try to it and see the difference yourself
