Can You Whiten Crowned Teeth?

  • Teeth Whitening

Dental crowns are a long-lasting solution for restoring damaged or weakened teeth, designed to blend naturally with your smile. However, one common concern many patients face is how their crowns respond to teeth whitening treatments.

This article explores what you need to know about whitening crowned teeth, what to expect when your natural teeth change shade, and the cosmetic options available to maintain a bright, even smile.

Why Crowns Don’t Respond to Whitening

Unlike natural teeth, dental crowns are made from materials such as porcelain or ceramic. These materials are non-porous and do not respond to whitening agents, such as hydrogen peroxide, in the same way enamel does. While professional teeth whitening can significantly brighten your natural teeth, it won’t have any effect on the colour of your crowns. While crowns won’t change colour, many patients still want to understand How to whiten teeth that are yellow using methods that work on natural enamel

This can sometimes lead to a mismatch in shade, especially if your crown was colour-matched to darker teeth before whitening.

What Are Your Options?

If you’ve had a crown for a few years and notice a difference in shade between your natural teeth and the crown, you’re not without options:

  • Whiten natural teeth first: If you’re planning to have a crown placed, you might consider whitening your natural teeth beforehand. This way, your crown can be colour-matched to your brighter, freshly whitened smile.
  • Replace older crowns: For those with crowns that no longer match surrounding teeth, replacement may be the most aesthetic option. A dentist can remove and refit a new crown matched to your current tooth shade.
  • Consider other cosmetic treatments: If you’re looking for a full smile refresh, treatments like composite bonding or veneers might be used alongside crown replacement for a more uniform result.

When to Speak With Your Dentist

If you’re considering whitening your teeth and already have one or more crowns, speak to a dentist before starting treatment. They can advise on the best timing, sequence, and options to keep your smile consistent. In many cases, the order of treatments can make all the difference between a subtle mismatch and a seamless result.

FAQs

Will whitening treatments damage my crowns?

No, whitening agents won’t damage crowns, but they won’t alter their colour either. They are designed to be stain-resistant and unaffected by bleaching agents.

The materials used in crowns can’t be lightened through traditional whitening methods. The only way to “whiten” a crown is to replace it with a new one matched to your desired tooth colour.

That’s perfectly possible. Please note that any existing crowns will remain the same colour, and there may be a slight contrast between the two. Your dentist can help you plan accordingly.

In most cases, it’s recommended to complete your whitening treatment first and wait a short period before fitting a new crown. This ensures the final colour is stable before matching.
