Tooth color is very important for individuals in providing dental aesthetics. In some cases, professional cleaning, such as tooth surface cleaning and polishing, to remove stains and tartar, is insufficient to optimize tooth color. In this case, the tooth color can be made desired with a correct whitening treatment. Bleaching is the most recommended and used cosmetic dentistry procedure all over the world. Its safety has been proven, and no side effects or complications have been encountered in the long term. It is a method that is easy to apply, practical and satisfies patients in a very short time with its fast results.
