Vicco vajradanti dental powder is in market from last 50years my dad was using from when he was small. now I am using from 2years, these powder is very powerful. it helps in making teeths and gems stronger. these powder also makes your teeth whiter and removes breath odour. packaging of the bottle is good. and you should used these powder twice daily. its very benefical. and its doesnt not have flavour as it is herbal and natural product.
