Natural teeth have pores which allow teeth whitening to absorb and remove stains. Artificial dental work such as crowns or veneers are color matched at the time they are installed and do not have pores. The color of your crown or veneer cannot be change (unless it is replaced).
Teeth whitening will not whiten or damage artificial dental work including crowns, veneers, bridges, permanent retainers, bonding, or fillings. The teeth whitening process can lighten teeth which have porcelain veneers.
Note: Dentists recommend that prior to getting veneers, caps, or crowns, clients whiten their teeth. This way, the restoration work will be installed to match your whitest possible natural teeth.
