How To Whiten Crowns And Bridges: Achieving A Brighter Smile

Maintaining a bright, white smile is important for many people, but achieving this can be more challenging if you have dental restorations like crowns and bridges. Unlike natural teeth, dental crowns and bridges don’t respond to traditional whitening agents in the same way. This guide explores the best methods for whitening crowns and bridges, ensuring your entire smile is as radiant as possible. We will cover why tooth discoloration occurs, the effectiveness of various whitening treatments, and practical tips for maintaining a consistent tooth color.

Understanding Tooth Discoloration And Dental Restorations

Tooth discoloration can occur for several reasons, including aging, dietary habits, smoking, and poor oral hygiene. While natural teeth can often be whitened using over-the-counter or professional treatments, dental crowns and bridges present a unique challenge. These restorations are typically made from materials like porcelain or ceramic, which do not react to whitening agents like hydrogen peroxide or carbamide peroxide in the same way natural teeth do.

Why Traditional Whitening Agents Don’t Work On Dental Crowns and Bridges

Traditional whitening agents, such as hydrogen peroxide and carbamide peroxide, work by penetrating the enamel of natural teeth to break down stains. However, dental crowns and bridges are made from porcelain or ceramic, which are non-porous materials. This means that while these agents can remove surface stains, they cannot change the intrinsic color of the restoration itself. Therefore, achieving whiter teeth with dental crowns and bridges requires a different approach.

Effective Methods For Whitening Crowns And Bridges

  1. Professional Cleaning and Polishing: The first step to whitening crowns and bridges is to have them professionally cleaned and polished by your dentist. This process can remove surface stains and plaque buildup that may be dulling your smile. Regular dental cleanings are crucial for maintaining the appearance of both natural teeth and dental restorations.

  2. Whitening Toothpaste: While whitening toothpaste cannot change the intrinsic color of crowns and bridges, it can help remove surface stains and prevent new ones from forming. Look for a toothpaste that contains gentle abrasives and is specifically formulated for use with dental restorations.

  3. Replacement of Discolored Crowns and Bridges: If your crowns or bridges have become significantly discolored and no amount of cleaning can restore their original appearance, replacing them might be the best option. Your dentist can match the new restorations to the current shade of your natural teeth for a seamless look.

  4. Custom-Made Whitening Trays: For patients with both natural teeth and dental restorations, custom-made whitening trays can be used to whiten the natural teeth while protecting the restorations. These trays are filled with a whitening gel, usually containing carbamide peroxide, and worn over the teeth. Your dentist can help ensure that the gel does not come into contact with the crowns or bridges to prevent any potential damage.

  5. Whitening Treatments for Natural Teeth: If you are considering whitening treatments, it’s important to whiten your natural teeth before getting crowns or bridges placed. This way, the dental restorations can be matched to the new, lighter shade of your natural teeth, resulting in a uniform appearance.

Maintaining Whiter Teeth With Dental Restorations

Dental Bridge Cleaning

Once you have achieved the desired level of whiteness for your natural teeth and matched your crowns and bridges accordingly, maintaining your smile is essential. Here are some tips for keeping your teeth and dental restorations looking their best:

  • Practice Good Oral Hygiene: Brush your teeth twice a day with a whitening toothpaste and floss daily. This helps prevent plaque buildup and surface stains on both natural teeth and restorations.

  • Regular Dental Checkups: Visit your dentist regularly for professional cleanings and checkups. Your dentist can keep an eye on the condition of your crowns and bridges and address any discoloration or other issues promptly.

  • Avoid Stain-Causing Foods and Drinks: Limit your consumption of coffee, tea, red wine, and other foods and drinks that can stain your teeth. If you do indulge, rinse your mouth with water afterward to minimize staining.

  • Quit Smoking: Smoking is a major cause of tooth discoloration. Quitting smoking not only benefits your overall health but also helps keep your teeth and dental restorations looking whiter.

The Role Of Advanced Whitening Procedures

For those seeking more advanced solutions, there are professional whitening procedures that can enhance the overall appearance of your smile:

  • Laser Teeth Whitening: This in-office procedure uses a laser to activate a whitening agent applied to your natural teeth. While it won’t change the color of crowns and bridges, it can significantly whiten your natural teeth, allowing for better color matching if you need to replace any restorations.

  • Porcelain Veneers: If you are looking for a more permanent solution to achieve a uniformly white smile, porcelain veneers can be applied to the front surfaces of your teeth. Veneers can be customized to match the color of your existing crowns and bridges, creating a seamless appearance.

Choosing The Right Whitening Products

When selecting whitening products, it’s important to choose those that are safe for use with dental restorations. Here are a few options:

  • Whitening Strips: Some whitening strips are safe for use with dental restorations, but they should be used with caution. Consult your dentist before using them to ensure they won’t damage your crowns or bridges.

  • Whitening Gels and Pens: These products can be applied directly to your natural teeth to remove stains. Be careful to avoid getting the gel on your crowns and bridges.

  • Natural Whitening Remedies: Some people prefer natural whitening remedies, such as baking soda or activated charcoal. While these can help remove surface stains, they should be used sparingly to avoid damaging tooth enamel and dental restorations.


Whitening crowns and bridges can be tricky, but it’s possible with the right approach. These dental restorations need special care when it comes to whitening. Traditional whitening products don’t work the same way on crowns and bridges, so it’s important to use the right methods.

Regular dental cleanings, good oral hygiene, and careful use of whitening products can help keep your smile bright. Sometimes, replacing old or discolored crowns and bridges might be necessary to match your natural teeth. Always consult your dentist before starting whitening treatments to ensure you get the best results.

A bright smile not only looks good but also reflects good oral health. By following these tips and working with your dentist, you can maintain a consistent, confident smile that makes a great impression.
