Can I Whiten My Crowns and Veneers?

Posted in Teeth Whitening

The short answer? No.

This simply boils down to what crowns and veneers are made up of.

Let’s first consider how whitening action affects natural teeth.

When stain (from food, coffee, cigarette smoke, etc.) first builds up on a tooth surface, it can usually be scrubbed away with a toothbrush, a gentle abrasive in toothpaste, or during a professional cleaning. If the stain is left on the teeth for a long period of time, it can start to build up deep within channels in the porous outer layer of the tooth, which is called the enamel. Stain this deep cannot be removed by surface cleaning, but only by bleaching.

Peroxide-based bleach can access those channels in the enamel to chemically lift stain. This is how whitening works.

Crowns and veneers, on the other hand, are not made of natural tooth structure, and so they are not porous. They cannot pick up stain as teeth do, and will not be affected by tooth-whitening products as teeth are.

When crowns and veneers were first placed, they were designed to have a color that most closely matched that of your natural teeth, at the time. Their color cannot be altered, afterwards. If you choose to whiten your teeth later on, the shade of your crown or veneers will not change, but will likely appear darker in contrast with the lightened teeth.

If you have crowns or veneers and you seek to have your teeth whitened, talk to your dentist. He will probably suggest that the best option is to update your crowns or veneers to match the lighter shade you’ve achieved.
