Bleaching is the healthiest and most harmless treatment to have whiter teeth. In the tooth bleaching method, nothing is added to the tooth structure and the whitening agent with a function similar to Vitex removes the yellowness of the teeth. The slight temporary sensitivity of the teeth, the lack of permanent results and the limitation in the amount of teeth whitening are among the disadvantages of this treatment method. Bleaching can be done in two ways, in the office and at home. The best results are obtained by using both methods.
