What Teeth Whitening Works on Crowns

Teeth whitening is a popular cosmetic dental procedure that can help enhance the appearance of your teeth. However, when it comes to dental crowns, not all teeth whitening methods are suitable. In this article, we will discuss ten aspects of teeth whitening on crowns, including its effectiveness, safety, potential risks, and cost.

1. What are dental crowns?

Dental crowns are tooth-shaped caps that are placed over damaged or severely discolored teeth to restore their size, shape, and strength. They are typically made from materials like porcelain, ceramic, or metal alloys. Crowns are customized to match the color and shape of your natural teeth, providing a seamless appearance.

While dental crowns are durable and resistant to staining, they are not completely immune to discoloration over time. Factors like consuming colored foods and beverages, smoking, and poor oral hygiene can cause the crowns to lose their brightness.

2. How does teeth whitening work on crowns?

Teeth whitening products mainly target the natural enamel of teeth, bleaching away stains and discoloration. However, teeth whitening treatments have limited effectiveness on dental crowns because the materials used to make crowns do not respond to bleaching agents like natural teeth enamel.

The bleach used in teeth whitening treatments cannot penetrate the surface of the crown material, making it difficult to lighten the color of the crown. As a result, teeth whitening treatments usually have little effect on the overall appearance of dental crowns.

3. Alternative whitening options for crowns

If you have dental crowns and want to achieve a whiter smile, there are alternative options available:

a) Replacement: If your dental crowns have become significantly discolored and you desire a whiter smile, considering replacing them with new crowns is a viable option. By opting for whiter crown materials, like zirconia or porcelain fused to metal, you can achieve a brighter and more uniform smile.

b) Adjacent teeth whitening: Teeth whitening treatments can effectively lighten the color of natural teeth adjacent to dental crowns, making the crowns appear brighter in comparison. This method can help create a more cohesive and blended smile.

4. Considerations for teeth whitening on crowns

Before undergoing any teeth whitening treatment involving dental crowns, there are several important considerations to keep in mind:

a) Shade matching: If you plan to whiten your natural teeth, it is crucial to establish the desired shade beforehand to ensure your new crown matches the updated color.

b) Dental sensitivity: Teeth whitening treatments can sometimes cause temporary sensitivity. However, dental crowns do not experience sensitivity. It is important to understand that only the natural teeth will be affected by the whitening treatment.

c) Professional consultation: It is always recommended to consult with a dental professional before pursuing any teeth whitening treatment. They can assess the condition of your dental crowns and provide personalized recommendations based on your specific needs and goals.

5. Potential risks and precautions

While teeth whitening treatments are generally safe, there are a few potential risks associated with whitening on dental crowns:

a) Uneven color: Since dental crowns do not respond to bleaching agents, there is a risk of uneven coloration between the natural teeth and the crowns after whitening. This may result in an unnatural appearance.

b) Irritation or damage to gums: Improperly applied whitening agents can irritate the gums or even cause damage to the crowns. It is important to carefully follow the instructions provided by the dental professional or teeth whitening product manufacturer.

c) Shortened lifespan of dental crowns: Aggressive teeth whitening treatments or using unsuitable products can potentially reduce the lifespan of dental crowns. It is crucial to choose whitening methods that are safe for dental crowns and follow the professional guidance.

6. Average cost and price range

The cost of teeth whitening on crowns can vary depending on various factors, including the location, dentist's experience, and the extent of the treatment required. On average, teeth whitening treatments range from $300 to $1,000 per arch. However, the price can be higher for more complex cases.

FAQs about teeth whitening on crowns

1. Can I use over-the-counter whitening products on my dental crowns?

No, over-the-counter whitening products are not effective on dental crowns. It is best to consult with a dental professional for appropriate whitening options.

2. Is there any way to prevent dental crowns from staining?

While dental crowns are stain-resistant, it is recommended to minimize consumption of foods and beverages that are known to cause staining, such as coffee, red wine, and tobacco.

3. How long does teeth whitening on adjacent natural teeth last?

The longevity of teeth whitening on natural teeth can vary depending on individual habits and oral hygiene. With proper care, the effects can last for several months to a few years.
