1. The straight answer
No — whitening strips can’t whiten fillings, crowns, veneers, or any dental restoration.
These materials (usually porcelain or resin composite) don’t respond to peroxide in the same way natural enamel does. Whitening strips are formulated to oxidize stains inside tooth enamel, not on synthetic surfaces.
💡 That means peroxide can lift stains on your natural teeth, but your crowns or fillings will stay the same color they are now.
2. Why restorations don’t whiten
Fillings, crowns, and veneers are color-stable materials — they’re made to resist the same types of stains that whitening targets.
-
Hydrogen peroxide breaks down organic pigments inside enamel.
-
Porcelain and resin are non-porous — peroxide can’t penetrate.
-
The shade of your restoration was chosen at the dentist to match your natural teeth at the time it was placed.
That’s why, after whitening, your natural teeth may become brighter while your restorations stay unchanged — sometimes making them appear slightly darker by contrast.
3. What whitening strips can do in these cases
While they can’t change the color of restorations themselves, whitening strips still help by:
✅ Removing surface stains from the edges around fillings or crowns.
✅ Whitening the surrounding enamel so your smile looks cleaner and brighter overall.
✅ Refreshing the balance of color between your teeth and restorations if discoloration is minor.
So yes — strips can improve your overall smile brightness, even if they can’t physically alter the color of the restoration itself.

6. How to manage restorations after whitening
If you’ve whitened and your fillings or crowns now appear darker than the rest of your teeth:
-
Wait two weeks — your enamel shade stabilizes after whitening.
-
Visit your dentist if mismatch remains; they can polish or replace older restorations to match your new shade.
-
Maintain brightness with Expertwhite Max HP Foam — it prevents new stains on both enamel and restorative surfaces.
