Dental crowns are custom-made caps designed to cover and protect a damaged tooth. They restore the tooth's shape, size, and function, and can be made from a variety of materials, including porcelain, porcelain-fused-to-metal (PFM), metal, zirconia, and resin. Crowns are often used to:

• Protect a weakened tooth from further damage
• Restore a broken or severely worn tooth
• Cover a tooth with a large filling or after a root canal
• Improve the appearance of misshapen or discolored teeth
• Cover dental implants

Unlike natural teeth, dental crowns are made from non-porous materials. These materials, such as porcelain and zirconia, do not respond to traditional teeth whitening treatments that use bleaching agents to remove stains. Here's why:

1. Non-Porous Nature: The materials used in dental crowns are non-porous, meaning they do not absorb the bleaching agents in whitening products. While these materials are excellent for resisting stains, they also cannot be lightened beyond their original color once they are set.
2. Color Stability: Dental crowns are designed to have stable, long-lasting color. This stability is beneficial for maintaining a consistent appearance over time, but it also means that the shade of a crown cannot be changed once it has been made.
3. Matching Natural Teeth: Crowns are typically color-matched to your natural teeth at the time of placement. If your natural teeth change color due to whitening treatments or other factors, the crown will not change to match them, potentially resulting in a noticeable color difference.

If you're unhappy with the color of your dental crowns or if they no longer match your natural teeth due to whitening treatments, there are a few alternatives to consider:

1. Replacing the Crowns: The most straightforward solution is to replace the existing crowns with new ones that match the desired shade of your natural teeth. This process involves removing the old crowns and taking new impressions to create crowns in the preferred color. While effective, this option can be costly and time-consuming.
2. Whitening Natural Teeth First: If you are considering whitening your natural teeth and have dental crowns, it's best to whiten your natural teeth first. Once you've achieved your desired tooth shade, your dentist can then place new crowns that match this shade.
3. Composite Bonding: In some cases, a thin layer of composite resin can be applied to the surface of the crown to alter its color. However, this is usually a temporary solution and may not work for all types of crowns or significant color changes.
4. Professional Cleaning and Polishing: While crowns cannot be whitened, regular professional cleanings can help maintain their appearance by removing surface stains and polish the crown's surface.

To keep both your dental crowns and natural teeth looking their best, consider the following tips:

• Avoid Stain-Causing Foods and Beverages: Limit the consumption of foods and drinks that can stain teeth, such as coffee, tea, red wine, and certain berries.
• Quit Smoking: Tobacco can stain both natural teeth and crowns, leading to an uneven appearance.
• Practice Good Oral Hygiene: Brush and floss regularly to remove plaque and prevent discoloration. Use a non-abrasive toothpaste to avoid scratching the crown's surface.
• Regular Dental Visits: Regular check-ups and cleanings can help maintain the appearance and health of your crowns and natural teeth.
