Can You Whiten Crown Teeth? Understanding the Limitations of Whitening Treatments on Dental Crowns
Many people strive for a bright, white smile, but what happens when you have dental crowns? Can you whiten crown teeth? The short answer is: no, you can't whiten crowns themselves. This is because crowns are made of porcelain or other materials that don't respond to whitening treatments like bleaching gels or light-activated systems. These treatments are designed to work on natural tooth enamel, not artificial restorations.
Let's delve deeper into the reasons why whitening crown teeth is ineffective and explore alternative options for achieving a uniformly bright smile.
Why Whitening Treatments Don't Work on Crowns?
Dental crowns are made from materials that are not porous, unlike natural tooth enamel. Whitening agents work by penetrating the porous enamel and breaking down stains within the tooth structure. Since crowns are non-porous, these agents simply can't penetrate the surface to lighten the material. Trying to whiten a crown is akin to trying to bleach a piece of ceramic – it simply won't change color.
What Happens if I Try to Whiten My Crowned Teeth?
Attempting to whiten teeth with crowns using over-the-counter or professional whitening products will have no effect on the crown itself. However, it could potentially whiten your natural teeth, creating a noticeable color discrepancy between your crowns and your natural teeth. This could result in an uneven and unattractive smile.
Can I Whiten the Teeth Underneath My Crowns?
This is a critical question, often missed in discussions about crown whitening. Before a crown is placed, the underlying tooth is prepared, typically involving the removal of some enamel. While you can't whiten the crown itself, if the natural tooth under the crown was discolored before the crown was placed, it won't be affected by whitening. Therefore, there's no point in trying to whiten the teeth under the crowns after the fact. The existing discoloration will remain unchanged.
What Are My Options for a Brighter Smile with Crowns?
If you're unhappy with the color of your crowns or the overall appearance of your smile, several options exist:
-
Replacing the Crowns: The most effective solution is to replace your existing crowns with new ones that match your desired shade. This requires a consultation with your dentist, who will match the color of your new crowns to your whitened natural teeth or your preferred shade. This is a more permanent solution and requires more time and financial investment.
-
Whitening Natural Teeth First: Before getting crowns, consider whitening your natural teeth to your desired shade. Then, your dentist can match the crowns to those already-whitened teeth. This is the ideal approach to avoid color discrepancies.
-
Veneers: For patients with multiple crowns or extensive discoloration, porcelain veneers might be a suitable option. Veneers are thin shells bonded to the front surface of the teeth, offering a more aesthetically pleasing result. They are also capable of masking discoloration.
How Can I Maintain the Brightness of My Natural Teeth Around Crowns?
Even though you can't whiten the crowns themselves, you can maintain the brightness of your natural teeth by following these tips:
- Maintain excellent oral hygiene: Brush and floss regularly.
- Avoid staining substances: Limit or avoid coffee, tea, red wine, and tobacco.
- Use a whitening toothpaste: Choose a toothpaste specifically formulated to remove surface stains.
- Regular dental checkups: Professional cleanings can remove stubborn stains and help maintain a bright smile.
Ultimately, understanding the limitations of whitening treatments on crowns is crucial for managing expectations and making informed decisions about your smile's aesthetic enhancement. A consultation with your dentist will help determine the best course of action based on your individual circumstances and desired outcomes.
