Can Dental Crowns Be Whitened?

Not to burst your bubble, but in short: no, they can’t. For those of you would-be teeth whitening patients, dental crowns are highly resistant to stains caused by coffee, wine and even cigarettes. Unfortunately, this means that they’re also highly resistant to all teeth whitening treatments. So, this means that you’ll be left with one option should you want your crowns to match the rest of your teeth once they’ve been whitened: replacing them. At Bite Dental Works, we take pride in the care and service we provide for our patients. Let our experts show you why you can’t simply whiten your dental crowns.

Why Do Teeth Stain but Porcelain Crowns Don’t?
Your teeth get stained in two different ways. The first way is when the enamel of your teeth absorbs the colour from the various different foods you ingest on a daily basis. This superficial staining can eventually seep into the enamel of your tooth and cause stains that you might not get rid of so easily. The second type of stain is caused by severe decay and death of a tooth.

The reason porcelain crowns won’t stain is that they’re made from a much stronger and denser material than your teeth. The discolouration doesn’t have the same opportunity to seep its way into your dental crown. Superficial stains have trouble bonding to the porcelain. Simply brushing your teeth regularly should be enough to ensure that your crowns are always the same colour as the day they were installed.

Don’t Use Whitening Treatments
If you have dental crowns, visit our dentist in Calgary on MacLeod Trail before having your teeth whitened. Whitening treatments will usually only make things worse. Because your dental crown won’t respond to the whitening treatment, having your teeth professionally whitened will likely cause your teeth to become whiter than the crown and create a strange inconsistency in the colour of your teeth (especially if you only have one crown). The same is true if you let your teeth get too stained. Your crown will always remain a constant colour. So, be careful of what you do to the colour of your teeth.

Keep an Eye on the Colour of Your Crowns
If you do notice an unnatural discolouration or darkening of your crowns, visit your dentist right away, as this may be a sign of problems with the underlying tooth that need to be addressed immediately.

In the end, the only way to have your crowns whitened is to have them replaced and the colour matched to your newly whitened teeth.
