Toothpaste with whitening  is one of the cheapest and easiest ways to help whiten your teeth.  Toothpaste with whitening is really no more costly then toothpaste without whitening. Since you are having to brush your teeth twice a day any way, if you are wanting to brighten up your smile this may be one good affordable way to do so.   Toothpaste with whitening is not consider a bleaching product.  Whitening toothpastes focus more on mild abrasion, working on the discolored surface each time you brush your teeth. Results can be noticeable, however it can take much longer period for that to happen compare to other whitening products.
