Dental crowns do not respond to teeth-whitening treatments because they are not porous, notes Southeast Family Dental.

Dentists color-match crowns as well as tooth-colored fillings to the color of the patient's natural teeth at the time they are applied, states Charles N. Stanfield, D.D.S. Cosmetic and Family Dentistry. Thus, if a patient undergoes a teeth-whitening bleaching treatment, the natural teeth take on a whiter shade, while any crowns or fillings retain the shade of the natural teeth prior to the whitening process. This may have the effect of making the crowns and fillings appear even darker than they previously appeared due to the contrast between them and the lightened natural teeth. For this reason, patients with crowns or other man-made dental materials on their front teeth often must have the artificial materials remade and reapplied after the bleaching treatment is complete to achieve the desired result.

An alternative to replacing individual crowns is receiving a full-mouth set of crowns or veneers in the desired shade, explains Southeast Family Dental. This option eliminates future need for whitening treatments.
