Is there are any difference between the iWhite polishing paste versus normal iWhite toothpaste? Can one use normal iWhite toothpaste to polish?

The polisher paste has been designed to only address tartar on the dental surface for that a specific gel has been developed with a high RDA (Relative Dentin Abrasivity) in combination with pyrophosphates and specific thickness. The iwhite toothpaste has other therapeutic end goals such as whitening, remineralization, removing stains and cleaning.
