When a discoloring agent penetrates the internal structure of a tooth, it's referred to as intrinsic staining. These stains cannot be removed through regular tooth cleaning or prophylaxis, but some may respond to bleaching.
There are two types of stains: Intrinsic and Extrinsic.
Intrinsic Stain
Intrinsic staining occurs when a discoloring substance permeates the inner tooth structure, making it resistant to conventional tooth cleaning methods. However, certain intrinsic stains can be effectively treated through bleaching.

Extrinsic Stain
When the external surface (enamel) gets stained, then the staining can be easily removed by prophylaxis or tooth cleaning. Minor staining gets vanished by instant teeth whitening
