How does whitening actually work?
Most whiteners use a peroxide-based chemistry. Peroxide compounds have the ability to whiten teeth through an oxidation process. It has been demonstrated that peroxide has the ability to penetrate the inner aspect of the enamel within a matter of only a few minutes after application. There are complex organic molecules within the tooth that reflect a specific wavelength of light and are responsible for the Teeth Whitening in Pewaukee. It is believed that by releasing free radicals, peroxide has the ability to oxidize the color-producing organic compounds found within the enamel’s matrix. When these organic compounds are oxidized, the residual molecules reflect less light, or can also be described as colorless, thereby creating a reduction or elimination of the discoloration — whiter teeth!
What peroxide compounds are used in a whitening system?
Current compounds are hydrogen peroxide and carbamide peroxide. In-store or over-the-counter whitening systems use hydrogen peroxide. In-office whitening can utilize both carbamide peroxide and hydrogen peroxide. Carbamide peroxide contains approximately 35 percent hydrogen peroxide. This is sometimes preferred because it is a more stable compound than hydrogen peroxide, which allows for a more predictable shelf life. Also, carbamide peroxide penetrates the tooth at a slower rate and can aid in more patient comfort and compliance, as well as better-controlled results.
