Dental whitening applications, which are among aesthetic dentistry applications, can be applied for aesthetic smile design or for whitening purposes only. Using tobacco and drinking dark-colored liquids such as coffee and tea penetrates into the layer formed on the enamel and they cause teeth to get yellow, stained and have an aesthetically unpleasant appearance. The results obtained in whitening processes which should be repeated periodically vary in the rage of 3 to 8 in tooth color.
Who Can Benefit From Teeth Whitening?
Teeth whitening can be easily applied to any natural teeth. Any individual over 18 can benefit from whitening application. This application is not suitable for pregnant women because it includes medication. Since there is not information about the effects of medication during pregnancy, it is appropriate to apply this non-urgent procedure after birth. Dentist examination is performed before teeth whitening in order to check whether there is any condition that prevents whitening. Since whitening application is only effective on natural teeth, there is no change in the color of the coated teeth. Therefore, whitening process should be performed before porcelain veneer treatment. Since the color of porcelain veneers does not change with this process, you may have to change the veneer or have a non-aesthetically pleasing appearance after the application.
How It’s Done?
The whitening process, also known as vital bleaching, is carried out with a solution containing hydrogen peroxide. Firstly, a protective gel is applied to the tooth surface. After applying the gel, the bleaching agent is applied to the tooth. Various sources are used to activate gel and they allow bleaching to start. Heat, laser or specialized light are among the most commonly used activating sources. The waiting period begins when the bleaching substance starts to work actively. The solution remains active for a certain period of time and the process is completed. The application time usually varies from 30 to 60 minutes. One session is performed every day. 1 or 2 sessions are usually sufficient for whitening. The application period may vary for the teeth that are overly stained or have a potential of turning yellow because of their structure.
