A bright, white smile is something many people strive for, and with the variety of teeth whitening options available, its easier than ever to achieve. But what happens if you have dental crowns, veneers, or other restorations? Can these materials be whitened like natural teeth? The answer is not as straightforward as you might hope. Lets take a closer look at how whitening works on natural teeth versus crowns and what options you have for achieving a bright smile with restorations.
Understanding How Teeth Whitening Works
Teeth whitening products and procedures work by breaking down stains on the surface of the teeth. These products typically contain hydrogen peroxide or carbamide peroxide, which bleach the teeth by removing stains from both the enamel and dentin layers. Natural teeth can absorb the bleaching agents, allowing them to become brighter over time.
However, when it comes to dental crowns, veneers, and other restorations, things get a little more complicated. Unlike natural teeth, crowns and veneers are made from materials like porcelain, ceramic, or composite resins, which dont react to whitening agents in the same way. Lets explore why this is the case.
Why Crowns Dont Respond to Whitening
Material Differences: Dental crowns, especially those made from porcelain or ceramic, are non-porous. This means they dont absorb substances like natural teeth do. While teeth whitening products work by penetrating the porous structure of natural enamel, crowns and other restorations have a smooth surface that doesnt allow the whitening agents to have any effect.
Color Stability: Porcelain crowns are designed to closely match the color of your natural teeth, and they maintain their color over time. However, if your natural teeth are whitened, the crowns may appear more noticeable because they wont change color along with your natural teeth. This can lead to a mismatch in color between your teeth and restorations, making the crowns look more prominent.
Staining Over Time: While crowns wont whiten, they can still accumulate surface stains from foods, drinks, or tobacco use. These stains are often easier to clean than stains on natural teeth, but they wont respond to traditional whitening treatments.
What Can You Do If You Want Whiter Teeth with Crowns?
If you have crowns and want to brighten your smile, here are a few options to consider:
Whiten Your Natural Teeth Before Getting Crowns: If youre planning to get dental crowns, its best to whiten your natural teeth beforehand. This way, your dentist can match the color of the crowns to the newly whitened shade of your teeth, giving you a more uniform and natural-looking smile.
Replace Old Crowns: If your crowns are discolored or have become worn over time, replacing them with new crowns that match the color of your naturally whitened teeth can restore your smiles brightness. This is often the best option if youve had crowns for many years and are now noticing a noticeable color difference between them and your natural teeth.
Touch-Up with Professional Cleaning: If your crowns have surface stains, a professional cleaning at McLevin Dental Clinic can help remove them. While this wont whiten the crowns, it can help restore their original luster and brightness.
Use Whitening Toothpaste: While whitening toothpaste wont change the color of your crowns, it can help remove minor surface stains. Choose a non-abrasive toothpaste to avoid damaging the crown material. Be sure to ask your dentist for recommendations on the best toothpaste to use with your specific restorations.
Consider Custom Whitening Trays: If youre looking for a more customized whitening approach, your dentist may recommend custom whitening trays. These trays are filled with a professional-grade whitening gel and are designed to fit your teeth perfectly. While they wont whiten your crowns, they can give your natural teeth a brighter appearance.
Can You Whiten Crowns at Home?
Many people look to at-home whitening products for a quick fix. However, as mentioned earlier, at-home whitening kits, strips, or gels will not work on crowns, as they dont penetrate the non-porous surface of the restoration. You should also avoid using highly abrasive products, as they could damage the crowns surface or cause wear.
What About Other Types of Restorations?
Just like crowns, other restorations like veneers and bridges are made from materials that do not respond to whitening treatments. Composite resin veneers or fillings are somewhat porous, so they may stain over time, but they wont lighten with traditional whitening methods either. If youre looking to whiten your smile and have restorations, talk to your dentist about your options for achieving a more uniform appearance.
The Bottom Line
While crowns and other dental restorations cant be whitened in the same way as natural teeth, there are still ways to ensure your smile remains bright and consistent.
