Can You Whiten Bonded Teeth?

When it comes to achieving a brighter and more confident smile, teeth whitening is a popular option. However, for individuals with bonded teeth, there may be some concerns about whether teeth whitening is suitable for them. 

In this article, we will explore the question, and provide you with all the information you need to know about dental bonding, teeth whitening, and how they can work together to enhance your smile.

Teeth bonding is a dental procedure that involves applying a tooth-colored resin material to the surface of the teeth. It is commonly used to repair chipped or cracked teeth, improve the appearance of discolored teeth, and close gaps between teeth. Bonding is a versatile treatment that can provide remarkable results, but it does have limitations when it comes to teeth whitening.

The Limitations of Whitening Bonded Teeth

Unfortunately, unlike natural teeth, bonded teeth do not respond to traditional teeth whitening methods in the same way. This is because the bonding material itself is not affected by whitening agents such as hydrogen peroxide. 

As a result, attempting to whiten bonded teeth using over-the-counter whitening products or professional teeth whitening treatments may lead to uneven coloration, with the natural teeth appearing lighter than the bonded areas.

It is important to note that while whitening bonded teeth may not be possible, there are alternative options available to enhance the appearance of your smile. Let’s explore some of these alternatives in more detail.

Effects of Whitening on Bonded Teeth

1. No Change in the Color of the Bonding Material

Unlike natural tooth enamel, the composite resin material used for dental bonding does not respond to traditional teeth whitening agents. Thus, while the natural tooth may become lighter, the bonded area retains its original color, leading to a mismatch in shades.

2. Potential for Uneven Appearance

Due to the lack of response from the bonding material to the whitening agents, patients may end up with teeth that have noticeably uneven coloration. This can be especially evident if a significant portion of the tooth’s visible area is covered with bonding material.

3. Risk of Damage to Bonding Material

Some whitening products, especially those with high concentrations of bleaching agents or abrasive substances, may deteriorate the surface of the bonded material, leading to roughness or even minor chipping.

4. Increased Tooth Sensitivity

While this is a common side effect of teeth whitening in general, in teeth with bonded areas, the difference in materials might mean different rates of temperature conduction, potentially exacerbating sensitivity issues in some patients.

5. Staining Along the Edges

The borders where the bonding material meets the natural tooth might be more susceptible to staining, especially if the seal isn’t perfect. After whitening, these stains can become more apparent due to the contrast between the whiter tooth and the stained edges.

6. Potential for Weakening the Bond

There’s some concern that certain whitening agents might interfere with the bond between the tooth and the composite resin, though this effect would be minimal and more research is needed.

Tips for Maintaining the Appearance of Bonded Teeth

1. Avoid Staining Substances

Limit consumption of foods and drinks known to cause stains, such as:

  • Coffee
  • Tea
  • Red wine
  • Berries
  • Tomato-based sauces
  • Curries
  • Soy sauce
  • Refrain from using tobacco products, which can yellow both natural teeth and bonding material.

2. Regular Dental Cleanings

Schedule professional cleanings at least twice a year. Dentists and hygienists can help remove surface stains and offer guidance on maintaining the bonded areas.

3. Use Non-abrasive Toothpaste

Abrasive toothpaste can scratch the surface of the bonding material, making it more susceptible to staining. Look for toothpaste labeled as suitable for dental restorations or veneers.

4. Avoid Chewing Hard Items

Avoid biting on hard objects like pens, ice, hard candies, and fingernails to prevent chipping or damaging the bonded material.

5. Wear a Mouth Guard

If you play contact sports or engage in activities with a risk of facial trauma, wear a protective mouth guard. This will help protect both the bonded teeth and natural teeth from potential injury.

6. Address Bruxism

If you grind or clench your teeth (a condition called bruxism), consult your dentist. Continuous grinding can wear down the bonding material. A night guard may be recommended to protect your teeth during sleep.

7. Maintain Good Oral Hygiene

Brush at least twice a day and floss daily. This helps remove plaque and prevent gum disease, which can affect the appearance and health of bonded teeth.

Alternatives to Whitening Bonded Teeth

1. Replace the Bonding

If you are unhappy with the color of your bonded teeth and desire a brighter smile, one option is to have the bonding material replaced.

By removing the existing bonding and replacing it with a new shade that matches your desired teeth color, you can achieve a more uniform and aesthetically pleasing smile. 

Consult with your dentist to discuss the best course of action for your specific situation.

2. Composite Veneers

Composite veneers are another popular solution for enhancing the appearance of bonded teeth. 

These thin shells of composite resin are custom-made to fit over the front surface of the teeth, improving their shape, size, and color. Unlike traditional porcelain veneers, composite veneers can be directly bonded to the teeth without the need for extensive tooth preparation. 

They are a more conservative and cost-effective option for individuals looking to enhance their smile.

3. Porcelain Veneers

For individuals seeking a long-lasting and highly aesthetic solution, porcelain veneers may be the answer. 

These wafer-thin shells of porcelain are custom-made to cover the front surface of the teeth, masking imperfections and creating a beautiful, natural-looking smile. 

Unlike bonding, porcelain veneers are highly stain-resistant and can provide a durable and stain-resistant solution for achieving a brighter smile.


In conclusion, while it may not be possible to whiten bonded teeth using traditional teeth whitening methods, there are alternative options available to enhance the appearance of your smile. From replacing the bonding to considering composite or porcelain veneers, it is essential to consult with a dental professional who can guide you toward the best solution for your specific situation. Remember, achieving a brighter and more confident smile is within reach, even if you have bonded teeth.
