Natural teeth have pores which allow teeth whitening gel to be absorbed and remove stains. Artificial and cosmetic dental work such as crowns, caps, fillings or veneers are color matched at the time they are installed and do not have pores. The color of your cap, crown or veneer cannot be changed (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.
