the downside abt using whitening toothpaste is sensitivity in the long run.whitening toothpastes only removes external stains.if ur teeth are very yellowish due to coffee,tea,smoking,whitening toothpaste will only offer a little help as those stains are likely to be more internal stains than external stains.
