How To Whiten Crowns and Bridges

Dental crowns and bridges play a crucial role in restoring and enhancing smiles, but over time, they may lose their original brightness due to various factors. In this comprehensive guide, we will explore effective techniques for whitening crowns and bridges, ensuring your smile remains radiant and confident.

Understanding Dental Crowns and Bridges

Dental crowns, often crafted from materials like porcelain or ceramic, can lose their luster due to aging or exposure to staining substances. Similarly, dental bridges, which replace missing teeth, may also show signs of discoloration. Understanding the composition of these dental restorations is essential to effectively address discoloration issues.

Identifying the Need for Whitening

Recognizing the signs of discoloration in dental crowns and bridges is the first step. Discoloration can result from various factors such as food and beverage consumption, smoking, or simply the natural aging process. Identifying the cause helps in choosing the most suitable whitening approach.

Professional Whitening Options

Consulting with a dentist is paramount before embarking on any whitening journey. Professional in-office whitening procedures, such as laser or light-activated treatments, offer efficient and immediate results. However, it’s crucial to note that whitening may not be as effective on dental crowns and bridges as it is on natural teeth. The materials used in these restorations, especially porcelain or ceramic, may not respond to traditional whitening agents in the same way.

While some improvement in color may be possible, it’s essential to manage expectations. Your dentist can provide a realistic assessment of the potential results based on the materials used for your crowns and bridges.

At-Home Whitening Solutions

For those who prefer the convenience of home-based solutions, whitening toothpaste, mouthwash, and DIY kits are viable options. However, the effectiveness of these products on dental restorations varies. Whitening toothpaste and mouthwash may have limited impact, and DIY kits may not provide uniform whitening across natural teeth and dental work.

Always follow the instructions on these products and consult with your dentist to determine the best approach for your specific case.

Natural Remedies for Whitening

Natural remedies like baking soda and hydrogen peroxide mixtures, along with oil pulling, provide alternative approaches to whitening. It’s important to note that while these methods may help with natural teeth, their effectiveness on dental crowns and bridges is uncertain. Moreover, using these remedies incorrectly can lead to damage or discomfort.

Again, consulting with your dentist before trying natural remedies is crucial to ensure you’re not risking the integrity of your dental work.

Tips for Maintaining Whiteness

Maintaining the whiteness of dental restorations involves adopting proper oral hygiene practices. Regular brushing and flossing, coupled with the right dental care products, contribute to a longer-lasting bright smile. Additionally, making lifestyle adjustments, such as choosing stain-resistant foods and quitting smoking, helps prevent further staining.

Risks and Considerations

While whitening procedures offer significant benefits, it’s essential to be aware of potential risks. Individuals with certain dental conditions should take extra precautions, and managing expectations regarding whitening results is crucial for a satisfactory experience.


In conclusion, maintaining the brightness of dental crowns and bridges requires a combination of professional guidance, suitable at-home solutions, and a commitment to proper oral care. By understanding the nuances of whitening techniques, individuals can achieve a brighter, healthier smile that boosts confidence and overall well-being.

FAQs about Crowns and Bridges

1. What mouthwash is best for crowns?

The best mouthwash for crowns is alcohol-free and gentle. Alcohol-free mouthwashes are less likely to cause irritation or dryness, which can be beneficial for the longevity of dental crowns. Look for a mouthwash that carries the ADA (American Dental Association) Seal of Acceptance, ensuring it meets the necessary standards for safety and effectiveness. Consult with your dentist for personalized recommendations based on your specific dental needs.

2. Do whitening strips work on crowns?

Generally, whitening strips are designed for natural teeth and may not be as effective on dental crowns and bridges. The materials used in these restorations, such as porcelain or ceramic, do not respond to traditional whitening agents in the same way as natural enamel. Attempting to whiten dental work with strips designed for natural teeth may result in uneven coloration. It’s advisable to consult with your dentist to explore professional whitening options tailored to your specific dental work.

3. How do I stop my crown from smelling?

Persistent odor around a crown may be a sign of an underlying issue, such as bacteria accumulation or decay. To address this concern, maintain a diligent oral hygiene routine, including regular brushing and flossing, paying special attention to the crown area. Consider using a non-alcoholic, antimicrobial mouthwash to help control bacteria. If the odor persists, consult with your dentist promptly. It could be indicative of a more serious problem that requires professional attention, such as an infection or a poorly fitting crown. Regular dental check-ups are crucial to ensuring the health and integrity of your dental work.
