Tooth discoloration varies in etiology, appearance, localization, severity and adherence to tooth structure. It may be classified as intrinsic, extrinsic and combination of both. Intrinsic discoloration is caused by incorporation of chromatogenic material into dentin and enamel during odontogenesis or after tooth eruption. Exposure to high levels of fluoride, tetracycline administration, inherited developmental disorders and trauma to the developing tooth may result in pre-eruptive discoloration. After eruption of the tooth, aging and pulp necrosis are the main causes of intrinsic discoloration. Coffee, tea, red wine, carrots and tobacco give rise to extrinsic stains. Wear of the tooth structure, deposition of secondary dentin due to aging or as a consequence of pulp inflammation and dentin sclerosis affect the light-transmitting properties of teeth, resulting in a gradual darkening of the teeth. Scaling and polishing of the teeth removes many extrinsic stains. For more stubborn extrinsic discoloration and intrinsic stain, a variety of tooth whitening options are available today, these include over-the-counter whitening systems, whitening tooth pastes and the latest option laser tooth whitening
