Crowns and Teeth Whitening? (photo)

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.

Unfortunately there is no way to correct the shade of an existing crown.  When you do whiten the your teeth, it is likely that the natural teeth will whiten, but the crown will stay the same color, making it appear more yellow.  It's great that the crown has lasted 14 years, but there really great options now with all porcelain crowns and when you replace it with an all porcelain crown you will not see that dark line at the gum line any more (the dark line is caused by the metal underneath the crown because it is probably a porcelain fused to metal crown).  Good luck!
