“How do you whiten crowns and veneers?”

You have to replace them if you want to change the shade.

Greetings,

Crowns and veneers are not porous like teeth are, so it is not possible to whiten them. Crowns and veneers can accumulate minimal amounts of staining over the course of many years and thus those stains can be removed while whitening normal dentition, but you will not see results as you will with your natural tooth structure. Because of this, we always advise that prior to the placement of any restorations, like fillings, crowns, or veneers, that you whiten your teeth to obtain an optimal esthetic result. That way, we can match your new dental work with your whitest tooth structure and maintain it by keeping up with whitening at home.

Hello,

Sorry, if you want them whiter, you will have to replace them. Porcelain veneers to cover them usually don't last very long. They will pop off probably within a year, and not cheaper than a new, improved crown.

Unfortunately, you’ll need to replace them if you want a lighter shade. porcelain doesn’t bleach.

Hi,

You don't whiten crowns or veneers. You have to replace them to change the color. They are made out of porcelain, and porcelain cannot be changed once made.
