Crowns and Teeth Whitening? (photo)

If you want to whiten your teeth know that the porcelain crown color or a veneer will NOT get whiter. If the color change of your natural teeth got much whiter with bleaching procedure, wait for couple of months then decide if you need to change the crown or a veneer. With bleaching teeth the color is not permanent, and it can revert back, unless you use more permanent solution like veneers, in which the color is stable.

Hi, thanks for your question!  Crown shades won't change when using bleaching/whitening products, so if you choose to whiten, know that the crown shade will stay the same, and the difference in shade between it and your other natural teeth will depend upon how your teeth whiten.  Should you choose to replace the crown at some point, a full-porcelain crown (not with a metal base), will ensure an extremely aesthetic result, and can be made to exactly match your "new" shade--good luck!

Unfortuately if you were to whiten your teeth, the porcelain will not change color along with your natural teeth. However, try the whitening and see what results you get. You may find that there may not be a drastic difference in color. If the dark like is a major concern too, the only was to remove it would be to replace it.
