Will laser teeth whitening also whiten my crowns? i'm thinking about have my teeth whitened, but also have a few crowns. will laser teeth whitening provide an even look, or does it react differently on surfaces that are not real tooth enamel?

The : The color of the porcelain is chosen when the crown is made to match your current tooth color. The same holds true for white fillings (composite or porcelain fillings). Whitening procedures are designed to whiten your enamel. Discuss your esthetic objectives with your dentist when consulting for this procedure. Depending on where the crowns are located, they may not affect your new smile.

Any : Any type of whitenig can affect only enamel and will not be effective on the crowns. However if the crown is all the way in the back having a darker crown will not be visible to other people and you will still have an advantage of a brighter smile after whitening. If the crown is in the front you cannot do the whitening unless you are planning to replace the crown.

Porcelain : Porcelain and other filling materials do not respond to the whitening process although I have seen badly discolored front fillings brighten slightly due to stain neutralization. It is the usual approach to whiten the natural teeth and then match the crowns to the new baseline color. If the existing crowns are not in your visable smile zone then it won't matter. If your crowns are now lighter than your natural teeth then there is the remote possibility that you will have a more pleasing match after whitening, but with no guarantee and with the understanding that should the whitening be so effective that your natural teeth brighten significantly you may need to replace your crowns.

NO! The : No! the porcelain of your dental crowns is impervious to the tooth whitening agents we use to whiten teeth. So it is always better to lighten your teeth and then make the crowns match them. Tooth enamel is a living vial structure that can have its color changed by tea and time and reversed to some degree by whitening. Dr neil mcleod dds dentistry that lasts - quality that counts.

No: The active ingredient in teeth whitening products will not whiten porcelain what crowns are made of. You can have surface stains removed from porcelain, however the color is the color!

Uneven shades!: Laser whitening and all other forms of teeth bleaching techniques are only going to work on natural teeth. You always have the option to bleach or whiten your natural teeth and than replace the crowns with new ones that match the improved shade. Good luck and remember how important that smile is to your overall appearance!

Thin veneers maybe?: Others are correct, short of whitening surface stains on dental restorations, peroxide whiteners won't change the color of ceramic materials. However, the shade of very thin prepless veneers can be effected by underlying tooth color. Aggressive tooth whitening can sometimes penetrate the tooth from behind to lighten this surface which may express itself as a lightening of the veneer.
