Can Implants Be Whitened Without Damaging Them?

Choosing to whiten stained implant crowns will not make a difference.  Whitening materials will only work on natural teeth and hence any form of a crown or a resin restoration will not alter its shade.  

The solution might be simple if a porcelain crown is stained due to external factors such as tabaco, coffee or tea.  A  polishing will likely remove the discolouration.  This can be done by your dental provider but make sure that a none abrasive polishing paste is used to prevent unnecessary scratching of the porcelain.

You should know that dental imlant crowns or any other crowns cannot be bleached.  Your dentist should have asked you initially whether you wanted to have your teeth whitened in order to make your crown match the bleached shade.  If the teeth are the same shade as your implant crown now, then you may need to have the crown changed for a lighter one to match when you bleach.  This is when it comes down to desire of a cosmentic enhancement and finances.  Good luck

The implant crown is made from a porcelain material that will not bleach. The crown will however pick up stain so frequent cleaning and polishing is needed. We like to use an aluminum oxide paste to remove stains and keep the polish of the crowns adequate. If you are going to be bleaching the teeth surrounding the implant crown, getting the hydrogen peroxide products on the porcelain should not cause any damage. I would warn you about the effects of nicotine and smoking on the health of the gums around the implant. Smoking causes the body to not be as effective at fighting infection. So imagine plaque buildup around the implant and the infection that will follow it could cause stability problems with your implant long term!

Smoking stains are more difficult to remove from implants than regular teeth because you can't use an ultrasonic cleaner to remove the stain.  However, they can be removed with a fine diamond polishing paste that will not scratch the porcelain.  It takes more time and a bit more effort but can be done effectively with a good dental hygienist.

Generally stain from the porcelain on a crown should not be difficult to remove by a dental professional during your cleaning.  It does not make a difference whether that crown is sitting on a dental implant or a tooth.  What concerns me most is the risk of Peri-implantitis in people who smoke.  Peri-implantitis is when the soft tissue and bone around the implant gets infected by bacteria.  Smokers are especially susceptible to this condition.  It occurs frequently enough that I and many implantologists do not place dental implants in people who smoke. I would suggest not smoking for many health reasons besides the one I just mentioned.  Good Luck!
