I personally have tested various systems - in-office and home - that are supposed to whiten teeth. However I feel the best results are obtained by simply enhancing the natural crystalline structure of the enamel with the nano-hydroxyapatite products in my daily protocol. It fills in microscopic cracks and defects minimizing staining, makes the enamel surface slick and smooth, and creates a white opaque layer that blocks incoming light and reflects back white light. The smile above is mine - a 70 year old who is an avid coffee drinker!

The toothpastes recommended in the "Daily Routine Products" tab are THE BEST for natural whitening.
