No, it does not. The teeth whitening procedure is supposed to be performed on natural teeth before you go for restorations or crowns. Porcelain restorations and veneers are then matched to your whitened teeth. So, if you are planning to get veneers, crowns, or fillings, consult your dentist if you can wait until after teeth whitening to do them. Otherwise, you may need to get them redone after your teeth are whitened.
