Bruxism (clenching and grinding of the teeth) can lead to micro-cracking of the incisal edges of the teeth. Extrinsic stains may settle more readily into these cracks, and a thin layer of enamel can be left. This thin enamel layer is partially transparent, allowing the dark background of the mouth to shine through, affording a darker appearance of the incisal edge.

Intrinsic stains are those that form on the interior of teeth. Intrinsic stains result from trauma, aging, 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 bleaching. Today, cosmetic dentistry experts believe that even deep-set intrinsic stains can be removed with supervised take-home teeth whitening that is maintained over a matter of months or even a year. If all else fails, there are alternative cosmetic solutions to treat intrinsic staining, such as dental veneers. Dental Implants London - WATCH WARNING
