A whitening treatment only affects your natural teeth. Everything that has been artificially applied such as fillings, crowns and facings, retain their original colour. Prior to the treatment, our cosmetic dentist will give you advice regarding the best course of action for repairs that are in prominent view.
If necessary, you can often simply have your dentist change or adapt the restorations so that they are the same colour as your natural whitened teeth. It is best to do this two weeks after the whitening treatment, since the final colour of your teeth will only then be visible. Most restorations are not directly noticeable after the treatment. In this case, it is not necessary to visit your dentist.
