Do tooth whitening products affect dental installations such as fillings and crowns?
Two types of material provide tooth-colored fillings and crowns: porcelain and composite. Porcelain reacts the way your teeth do, both to staining foods and to whitening treatments. If you have porcelain fillings, inlays or onlays, crowns, or veneers, they will whiten as your teeth do. If you have composite fillings or crowns, however, their color will not change with the use of either professional or at-home whitening treatments.
