Tooth discolouration: The two types of tooth stains
There are two categories of staining as it relates to the teeth: extrinsic staining and intrinsic staining.

Extrinsic stains are those that appear on the surface of the teeth as a result of exposure to dark-coloured beverages, foods, tobacco, and routine wear and tear. Superficial extrinsic stains are minor and can be removed with brushing and cleaning. Stubborn extrinsic stains can be removed with more involved efforts, like teeth whitening. Persistent extrinsic stains can penetrate into the dentin and become ingrained if they are not dealt with early.

Intrinsic stains are those that form on the interior of teeth. Intrinsic stains result from trauma, ageing, exposure to minerals (like tetracycline) during tooth formation and/or excessive ingestion of fluoride. In the past, it was thought that intrinsic stains were too resistant to be corrected by whitening. Today, cosmetic dentistry experts believe that even deep-set intrinsic stains can be improved with laser teeth whitening and a home care kit, which helps maintain your smile.
