Review on Britenz Natural Teeth Whitening Pen - 0.05 fl. oz. by Scott Wilson

Bought these for my wife who has been using Crest products for a while. After a few weeks we both noticed a noticeable improvement in the whiteness of their front teeth. It's not the same as teeth whitening at the dentist, but again, it's a lot cheaper. It seems that hydrogen peroxide is the main ingredient in all over-the-counter whitening products, and so the vehicle that the peroxide is mixed into is important. This material does not require rinsing, which means that the binder is essentially dissolved or evaporated. She hasn't reported any issues or side effects so I have to give the Britenz Tooth Whitening Pen a thumbs up. Oh yes, the portability and ease of use of the product anywhere is also a big plus.
