The said no.1 brand in advertisement ( Pepsodent) is big lie to customers.
The first thing is its full of chemicals , though it can give you instantly clean teeth within minutes but its just for sometimes and also artificial.
The super salt has just a bit different taste from ordinary pepsodent and nothing more.
It just clean teeth from outside but you will be amazed that behind your teeth there is yellow layer forming instead of cleaning it regularly which is called TARTAR which ultimately results in tooth decay.
Even worse is for kids who sometimes indulge the toothpaste inside the body which can result in more harm .
So ultimately there is just little benefits in using them rather big disadvantages thus the safe choice is choosing herbal toothpaste instead of any chemical toothpaste.
