Do All Teeth Whiteners Work on Crowns or Colored Fillings?

The answer is no!  You cannot bleach crowns or tooth colored fillings.  If you have these types of restorations and want your teeth whitened, you would have to replace the crowns/fillings following your bleaching procedure.  

Porcelain crowns never change color.  If you want to change the color of the crowns and veneers, you must replace them with new ones that are a different shade.  If you are considering having whiter crowns, think about whitening the teeth around the crowns first so that the dentist can match your  new crowns/veneers to your new white smile!

Teeth whiteners only work on natural tooth structure, so the shade of crowns and filling material will not change.  Your teeth will whiten, but the rest will not.  It is important to consider this before proceeding with the whitening process.  If you already have fillings on your front teeth, it's possible to redo the fillings with a lighter shade of filling material, and you could also redo a crown in a lighter shade if that's what you needed to do to have lighter teeth match the work you have done.  

It is not possible to whiten a crown or composite filling with whitening treatment. The enamel of teeth will lighten but the shade of the restorations will not change. Sometimes plaque or calculus on the teeth can be cleaned and help to make restorations look better but overall the original shade will be as white as it could possibly be without planning replacement.

 

You can not bleach porcelain crowns or white fillings. If one has crowns on front teeth that match the color before bleaching, they will stand out and appear darker next to the bleached natural teeth. Therefore, if bleaching is to be done, the patient needs to be informed about the need to change the old crown to match the newly bleached teeth.

 

It is advisable to bleach teeth first, let a week pass and then pick a matching shade to the new crown or veneers.

 

Only what you were born with will whiten.  Anything a Dentist puts in your mouth (crowns, fillings) will not whiten.  Good Luck, and enjoy your new whiter smile when you replace your stained one.

One of the biggest problems encountered when trying to whiten your teeth with peroxide-based teeth whitening products is you just may be opening a bigger  "can of worms" when natural teeth get whiter and fillings, veneers and crowns that show in your smile do not. Always be sure that you know, or your dentist shows you, where tooth colored fillings or other restorations have been placed (they often blend in and are not always noticeable) before whitening because you may have to consider changing a yellowish tooth colored filling after you finish.

Tooth whitening systems only will work on natural tooth structure.  Unfortunately they will not lighten any restoration

Unfortunately teeth whiteners do not work on crowns or filings.  The only way to change the color of existing restorations is to replace them.

No tooth whiteners work on  whitening colored fillings or crowns. In fact tooth whiteners will probably make the discolored restorations become more visible. I personally don't recommend whitening before having cosmetic work done either.  Many times you can get a change in color of the tooth structure, or underlying tooth structure as time goes by.  Furthermore, this can cause the appearance of  your restorations or teeth not to match each other anymore.
