Does Crest toothpaste really whiten teeth?

According to Crest, their toothpaste can help to remove surface stains and prevent new stains from forming. It can also help to remove plaque and leave teeth feeling cleaner, which can make them appear whiter. However, the degree of whitening will depend on the individual and how they use the toothpaste. It is important to note that toothpastes can only remove surface stains, and they cannot change the natural color of your teeth. To achieve a more dramatic whitening effect, you may want to consider using a whitening product, such as whitening strips or whitening trays.
