Tooth “whitening” is defined as any process that will make teeth appear whiter. There are two ways this is commonly done: bleaching and non-bleaching whitening products.
Often the terms “bleaching” and “whitening” are used interchangeably, but the U.S. Food and Drug Administration (FDA) states the term “bleaching” can only be used when a product contains bleach. A product is considered simply “whitening” when it removes food or debris from the teeth without bleach.
We use Carbamide Peroxide, which is in fact a “Bleach”. Bleaching products contain peroxide (hydrogen peroxide or carbamide peroxide) and these products remove both surface and deep stains on teeth and can cause teeth to become even lighter than their natural shade.
