Is there a type of mouthwash that whitens teeth best?

None: There are no mouth washes that can really whiten teeth. Don't listen to the marketing hype. If you want them whiter, consult with a dentist.

None....: To whiten teeth, it takes peroxide in the correct strength contacting the tooth surface for a sufficient length of time. Rinsing, even with peroxide, does not place the solution on the teeth for a long enough period of time to be effective. See your dentist for various options which include in-office teeth whitening, take home custom-constructed trays or a combination.
