NUPRO TEETH WHITENING
Nupro-Gold is a teeth whitening that is the same as the other products but causes less sensitivity than the other brands except Achromasia 17%. Uses glycerin (which causes sensitivity), potassium nitrate (see above) and fluoride (which slows down the teeth whitening process).
No doubt Nupro Teeth Whitening is a great teeth whitening product in the market.
