In an ideal world, brushing your teeth routinely would be enough to keep your set of pearly whites, well, pearly and white between routine dentist appointments. But alas, for many of us particularly those of us with a serious coffee habit , that's just not the case. We feel moved to hit up the local drugstore for whitening products to freshen up our smiles — perhaps without giving much thought to what those products actually are and how they work.

Our teeth are made of three layers : the outer white enamel layer; the underlying dentin layer composed of proteins namely collagen ; and the pulp in the center that houses nerves, blood vessels and connective that binds the tooth to our gums. And this latest research found that the hydrogen peroxide that serves as the active ingredient in whitening products could be hurting that protein-rich dentin layer. The study, led by Kelly Keenan, an associate professor of chemistry at Stockton University, treated extracted human teeth from cadavers with whitening strips, following the manufacturer instructions to leave them on for an hour. Researchers also immersed the teeth in artificial saliva and washed them, to simulate what teeth experience in a human mouth. Then they tracked the level of collagen and other proteins remaining in the dentin layer of the whitened teeth, and compared that to a control group of unbleached teeth, as well as to another set of teeth that were whitened three times.
