How to whiten dental crowns?

If you are wondering how to whiten dental crowns, the short answer is: traditional whitening methods do not work on crowns. Crowns are made of ceramic or zirconia, which do not respond to bleaching agents. However, there are effective ways to address discoloration, such as professional cleaning, polishing, or replacing the crown if necessary.

Dental crowns cannot be whitened with over-the-counter products. Professional options include cleaning, polishing, or replacement. To prevent staining, maintain good oral hygiene and avoid staining foods. Consult your dentist for the best course of action.

Traditional teeth-whitening methods simply do not work on artificial dental materials. Standard professional or over-the-counter whitening treatments rely on powerful oxidizing agents, primarily hydrogen peroxide or carbamide peroxide. These chemical agents work by penetrating the porous crystalline structure of natural tooth enamel and dentin to oxidize and break down deeply embedded stain molecules, known as chromogens.

Dental crowns, however, are entirely non-porous. Whether your crown is made of porcelain, zirconia, composite resin, or porcelain-fused-to-metal (PFM), its surface is completely impervious to peroxide-based bleaching gels. The chemical compounds cannot penetrate the material, meaning that applying whitening strips, custom trays, or undergoing an intensive in-office laser whitening session will leave the shade of your dental crown entirely unchanged.

The American Dental Association notes that whitening treatments are not effective on dental restorations like crowns. For more information, visit the American Dental Association's patient education resources.

How to Address a Discolored or Mismatched Dental Crown

If your dental crown appears darker or yellower than the rest of your teeth, it is usually due to one of two reasons: either the crown itself has surface stains, or your surrounding natural teeth have yellowed over time, making the crown stand out. Because you cannot chemically whiten the prosthetic material, you must approach the problem through alternative dental strategies.

1. Professional Dental Cleaning and Polishing

While the internal shade of a porcelain or zirconia crown cannot be altered, the surface can accumulate extrinsic stains from highly pigmented substances like coffee, red wine, tobacco, and dark sauces. In these instances, a dental hygienist can use specialized, non-abrasive polishing pastes and prophylaxis tools to lift surface debris and restore the crown's original factory glaze.

To keep your crowns looking bright, maintain excellent oral hygiene: brush twice daily with a non-abrasive toothpaste, floss around the crown margins, and rinse with an alcohol-free mouthwash. Limit consumption of staining beverages like coffee, tea, and red wine, and if you do indulge, rinse your mouth with water afterward. Avoid smoking, as tobacco can cause significant discoloration. Regular dental cleanings every six months are also essential.

2. Whitening the Surrounding Natural Teeth

If your natural teeth have yellowed due to age or diet, but your crown has maintained its original lighter shade, the resulting contrast can make your smile look uneven. In this scenario, you can whiten your natural teeth using supervised at-home trays or an in-office bleaching treatment until they closely match the color of your crown.

3. Replacing the Restorations

If your crown was originally matched to a darker tooth shade and you now desire a permanently whiter smile overall, the only definitive solution is to undergo a full professional teeth whitening regimen first, and then have your existing dental crown completely replaced to match your new, brighter shade.
