The two types of stains found in teeth known as extrinsic and intrinsic stains. Extrinsic stains refer to discolorations on the tooth’s surface resulting from heavily colored beverages, tobacco, foods, and wear and tear. These stains are typically less stubborn and may be removed by brushing and regular dental cleanings.
The more stubborn stains in this category may be removed by bleaching the teeth. You should keep in mind that although extrinsic stains occur on the surface of the tooth, if not treated early enough they can actually penetrate the enamel and become ingrained in the dentin. Intrinsic stains are formed within the tooth interior as a result of trauma, age, mineral exposure such as tetracycline during the formation of the tooth, and/or large levels of fluoride ingestion. With today’s technology even some of the deeper intrinsic stains may be removed at home with professional take-home teeth whitening kits provided by name ( Dentist) if maintained within a couple of months to a year.
