Can you whiten your smile when you have crowns or fillings?

Published October 20, 2026

In short

Yes, natural teeth can usually be whitened, but crowns, veneers, bonding and tooth-colored fillings do not change color, so restorations that show in your smile may end up darker than the lightened teeth around them.

The usual approach is to whiten first, let the shade settle, and then decide whether any visible restoration should be replaced to match.

Why restorations do not lighten

Peroxide works on tooth structure. Porcelain, ceramic and composite are not affected, so the American Dental Association states plainly that whitening will not work on caps, veneers, crowns or fillings, and that only natural teeth can be whitened (ADA; ADA).

Where it matters most

Front teeth and the edges of fillings on them. A filling on a back molar that never shows rarely matters. A crown on a front tooth, a bonded edge or a tooth-colored filling at the gum line of a front tooth will stand out if the teeth around it lighten.

What an examination maps

Which restorations are visible when you smile and talk, their condition, whether any need replacing anyway for a crack or a stained margin, and how much enamel there is to whiten. The ADA recommends an exam first, with radiographs when appropriate, and documenting existing restorations before whitening (ADA).

Sequencing

  1. Examination and a record of visible restorations
  2. Whitening of the natural teeth
  3. A settling period while the shade stabilizes
  4. A decision on which restorations to replace, matched to the new shade
  5. Replacement after a waiting period; dentists commonly delay bonding for a time after whitening

Questions to ask about existing restorations

Will the gel affect the margins or surface of my fillings? Which of my restorations will show after whitening? Would any need replacing anyway? What would replacing them involve? Costs for replacing restorations are a separate decision, and this guide does not state fees.

Next step: Request a consultation or call (805) 565-5111. A request is not a confirmed appointment; the office confirms times during its listed hours (Monday to Thursday, 8 am to 5 pm, plus select Fridays).
