Teeth whitening is a cosmetic solution in which colored organic and inorganic substances formed in the internal and external structure of the teeth are removed with tooth whitening gels.There are two types of whitening; clinical type and home type. Clinical type whitening is performed in the form of applying specially prepared gels to the teeth and accelerating the reaction with a light source or laser. In home type whitening, the patient performs the whitening process by putting the whitening agent into the thin and elastic plaque prepared by taking oral measurements.
