Perfect Bleach Office+ is suited for whitening individual or multiple discoloured, vital or devitalised teeth. The whitening success depends on the natural tooth shade as well as the intensity and cause of the discolouration. It is possible to whiten discolourations of organic origin, which generally have the following causes:
discolouration as a result of traumata
discolouration caused by medication (e.g. tetracycline)
Discolourations of inorganic origin, such as components of amalgam (silver), are not whitened, nor are restorations
