What store bought teeth whitener is the best?

Teeth whitener: Toothpaste and mouthwashes will not whiten teeth. Whitestrips will whiten parts but not all of the teeth. The most effective way to whiten teeth is in-office or custom tray whitening provided by your dentist. Whitening will not remove stains from the teeth...They need to be cleaned first in order for the whitening to be effective.

Be careful: Often store bought dental products are either ineffective or damaging to tooth structure. See your dentist for a thorough evaluation and determination as to the best way to whiten your teeth. - there are several options usually in everyone's price range.
