What is Teeth Whitening?
This is one way to lighten teeth by using chemical agents that break down stains that produce chromosomes on the surface of the teeth. It is also called bleaching because it is done by bleaching agents such as hydrogen peroxide or carbamide peroxide.
Tooth bleaching makes tooth whitening teeth lighter and helps remove stains and color. Whitening is not a one time process. If you want to keep the color bright, it needs to be repeated from time to time.
