Do whitening toothpastes and mouthwashes actually work?
The least expensive options are whitening toothpastes and mouthwashes. Designed to have whitening capabilities, toothpastes and mouthwashes work to 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. Whitening toothpastes affect surface stains and will mildly lighten your teeth.
