Do “whitening” toothpastes work?
All toothpastes actually help remove surface stains using mild abrasives. However, unlike bleaching materials used in professional whitening procedures, these products do not lighten the actual color shade of the tooth. Rather, whitening toothpastes affect surface stains to mildly lighten your teeth resulting on about a one shade improvement while professional whitening procedures such as custom trays or laser whitening can get your teeth 5-8 shades whiter.
