Teeth Whitening is among the most popular procedures in cosmetic dentistry. It is a completely safe and non-expensive process, which improves tooth color and its brightness. Whitening can be conducted either on vital or non-vital teeth. The whitening process can be performed: at home, by the patient (where individual customized trays are made by the dentist), in the dental office or by combining the above two methods.
Brushing and flossing are daily rituals to keep teeth as bright, white and healthy as possible. Teeth, however, may change color over time. This may be due to frequent consumption of coffee, red wine or tea. Nicotine from smoking is one of the main reasons for tooth discoloration. Another reason is when the enamel (outer shell of the tooth) becomes thinner over time and the next layer, dentin, is more yellowish in colour and begins tο be more prominent at a patient’s smile.
In many cases traumatized teeth tend to have a grayish tint and in this case a bleaching within the root canal after endodontic treatment is necessary for improving the color of the tooth.
Contraindications of Dental Bleaching
Dental Bleaching is contraindicated in pregnancy and breastfeeding periods. It is not recommended for patients under 18 and on sensitive teeth. Also bleaching is contraindicated on patients with advanced periodontitis (with exposed roots due to gum recession) and on patients who are allergic to any of the whitening agents.
Please note that bleaching (whitening) has absolutely no effect on pre-existing restorations in the mouth such as old fillings, crowns and bridges.
