The whitening agent

The whitening agent
Instead of "bleach", usually an agent such as a peroxide is used for teeth whitening. The peroxide is a mildly oxidizing agent, which chemically "scrubs" discolorizing material from the surface of the teeth when exposed for extended periods of time. Unfortunately, the duration required for effective whitening stretches past two or more hours. Patients who are non compliant on duration may have less effective cleansing action and end up wearing the teeth trays for even longer.
