In terms of aesthetics, when people are not satisfied with the color of teeth, it is one of the reasons to apply to dentists. Therefore, tooth whitening has an important place in aesthetic dentistry. It is among the indispensable treatments of smile design. Whitening is the method of removing the stains that are present in the tooth with special gels and special techniques and opening the existing color of the tooth. Therefore teeth whitening and tooth cleaning are completely different treatments. Whitening occurs in the structure of the tooth; teeth cleaning is the process of removing calculus and debris from the teeth.
