Discolouraton in anterior teeth is a cosmetic problem that definitely requires treatment in terms of patient psychology. Despite several alternatives such as crowns and laminate veneers in discolouration treatment, the first treatment of these teeth should be with bleaching methods. Whitening procedures are a treatment option that is easier to apply, less expensive and more conservative than other restorative methods. Although the secret of success in these treatments is knowing what caused the discolouration, it is also related to correct diagnosis and the correct decision of which whitening technique to use. The aim of this paper was to present the results of techniques used to restore the aesthetics of patients who presented with complaints of discolouration of the anterior teeth.
