Our Guest Teeth Whitening Technician Eugelkis Saray Explains The Process Of Whitening Your Teeth. Eugelkis Talks About Her Teeth Whitening Company, Photo Ready Smile.
Teeth whitening or teeth bleaching is the process of lightning the color of human teeth. Whitening is often desirable when teeth become yellowed over time for a number of reasons, and can be achieved by changing the intrinsic or extrinsic color of the tooth enamel. The chemical degradation of the chromogens within or on the tooth is termed as bleaching. Hydrogen peroxide is the active ingredient most commonly used in whitening products and is delivered as either hydrogen peroxide or carbamide peroxide. Hydrogen peroxide is analogous to carbamide peroxide as it is released when the stable complex is in contact with water. When in contact with water, carbamide peroxide converts into hydrogen peroxide at a ratio of 3:1. For example, whitening product containing 30% carbamide peroxide has about 10% of hydrogen peroxide. When it diffuses into the tooth, hydrogen peroxide acts as an oxidising agent that breaks down to produce unstable free radicals.
