How Does teeth whitening work?
Teeth whitening is a simple process. Whitening products contain bleaches. These bleaches break down the stains and your teeth whiter and brighter. What causes teeth staining? Over time, your teeth can go from white to not-so-bright for a number of reasons: Coffee, tea and red wine are some major staining culprits. What do they have in common? Intense colour pigments called chromogens that attach to the white, outer part of your tooth (enamel). Two chemicals found in tobacco create stubborn stains: Tar and nicotine. Tar is naturally dark. Nicotine is colorless until it’s mixed with oxygen. Then, it turns into a yellowish, surface-staining substance.
