One of the most common questions that patients have when considering dental bleaching or teeth whitening is whether or not it can whiten crowns or fillings. The answer is not as straightforward as one might think as it depends on the type of material used for the crowns or fillings.
Can Dental Bleaching Whiten Crowns?
When it comes to crowns the answer is generally no dental bleaching cannot whiten crowns. Crowns are typically made of materials such as porcelain ceramic or metal which do not respond to bleaching agents in the same way that natural teeth do. As a result, if you have crowns that are a different shade than your natural teeth dental bleaching will not be effective in whitening them.
Can Dental Bleaching Whiten Fillings?
The answer to whether dental bleaching can whiten fillings is also dependent on the type of material used for the fillings. There are two main types of dental fillings amalgam fillings and composite fillings.
- Amalgam fillings
- Composite fillings
Amalgam fillings are made of a silver-colored material that contains a combination of metals including mercury. These fillings do not respond to dental bleaching and will not change color as a result of the bleaching treatment.
On the other hand composite fillings are tooth-colored fillings made of a resin material. While composite fillings can be somewhat affected by dental bleaching they do not whiten to the same extent as natural teeth. As a result if you have composite fillings and are considering dental bleaching it is important to discuss your options with your dentist to determine the best course of action for achieving a more uniform shade for your smile.
Alternative Options for Whiter Crowns and Fillings
If dental bleaching is not an effective option for whitening crowns or fillings there are alternative treatments that can help achieve a more consistent shade for your smile –
- Veneers – Veneers are thin shells made of porcelain or composite resin that are bonded to the front surface of the teeth to improve their appearance. Veneers can be customized to match the shade of your natural teeth providing a consistent and uniform look for your smile.
- Replacing Crowns or Fillings – If your crowns or fillings are significantly discolored and affecting the overall appearance of your smile you may consider replacing them with newer restorations that better match the shade of your natural teeth.
- Professional Cleaning – Regular dental cleanings and check ups can help remove surface stains and maintain the brightness of your natural teeth as well as any restorations you may have. Your dentist can provide guidance on the best oral hygiene practices to keep your smile looking its best.
Dental bleaching is an effective treatment for whitening natural teeth but it may not be as effective for crowns or fillings made of certain materials. If you have crowns or fillings that are a different shade than your natural teeth it is important to consult with your dentist to explore alternative options for achieving a more uniform and aesthetically pleasing smile.
