Teeth whitening can effectively address two types of tooth stains: extrinsic stains and intrinsic stains. Extrinsic stains are surface stains caused by factors like food, beverages (such as coffee or red wine), tobacco, and poor oral hygiene. Intrinsic stains are stains that occur within the tooth’s structure and may be caused by factors like genetics, aging, certain medications, or dental trauma. Teeth whitening primarily targets extrinsic stains but can also improve the appearance of some intrinsic stains.
Teeth whitening is a gradual process, and it may require multiple treatment sessions to achieve the desired level of whiteness. The number of sessions required depends on the initial shade of your teeth, the whitening method used, and your individual response to treatment.
