Stains on teeth can be classified in one of two ways: extrinsic or intrinsic.
Extrinsic stains appear on the surface of your teeth. Intrinsic stains live between
the microcracks in your enamel and deep within your dentin (the layer of your tooth
underneath your enamel). Whitening toothpastes and mouth rinses may be able to remove
some of the extrinsic stains on your teeth. But only teeth whitening agents can remove
the stubborn extrinsic stains and the unsightly intrinsic stains that cause your teeth
to look discolored.
Opalescence gels contain an active whitening ingredient (either carbamide peroxide or
hydrogen peroxide) that penetrates your enamel to get to discolored molecules. Oxygen
molecules from the whitening agents react with the discolored molecules in your teeth,
breaking the bonds that hold them together. The oxygen molecules spread, whitening the
entire tooth. As a result, you are left with a brighter, whiter smile. 1
