Dental veneers are a widely used cosmetic solution designed to improve the appearance of teeth. They can help with discolouration, minor chips, or uneven tooth surfaces, providing a smooth, uniform smile. While veneers enhance aesthetics, it is important to understand that they do not make your teeth immune to cavities or other dental issues.

Veneers are available at Freshdental in Bayswater, London, as part of the clinic’s cosmetic dentistry services. Understanding how veneers work, how cavities can still occur, and the proper care needed can help maintain both their appearance and the health of your natural teeth.

What Are Dental Veneers?

Dental veneers are thin shells made from porcelain or composite resin that are bonded to the front surface of teeth. They are custom-made to match the colour, shape, and size of your natural teeth, enhancing your smile.

Veneers are primarily cosmetic. They cover the front surface of teeth but do not protect the entire tooth. The natural enamel underneath still exists and remains vulnerable to decay if oral hygiene is not properly maintained.

Can You Get Cavities with Veneers?

Yes, it is possible to develop cavities even if you have veneers. While the veneer itself cannot decay, the natural tooth beneath and surrounding it can still be affected. Cavities most commonly occur in the following situations:

  • Along the edges of the veneer: Plaque and food particles can accumulate where the veneer meets the natural tooth, increasing the risk of decay.
  • On uncovered tooth surfaces: Veneers only cover the front surface of teeth. The back and sides remain exposed to bacteria and acids, which can lead to cavities.
  • Under the veneer (rare): If bonding is not perfect or gaps develop, bacteria can infiltrate, potentially causing decay.

Veneers are designed to be durable and resistant to staining, but they do not replace preventive dental care. Maintaining good oral hygiene is essential to protect both the veneer and the underlying tooth.

Factors That Can Increase Cavity Risk with Veneers

Even with veneers, certain habits and conditions can make teeth more susceptible to decay:

  1. Inadequate oral hygiene: Brushing and flossing must be consistent to prevent plaque build-up around veneers.
  2. Frequent sugary or acidic foods and drinks: Sugar and acids contribute to enamel erosion and increase cavity risk.
  3. Bruxism (teeth grinding): Grinding or clenching can damage veneers and create small gaps where bacteria may accumulate.
  4. Improper placement or fitting: Poorly fitted veneers may allow bacteria to enter the area between the tooth and veneer.

Recognising these factors helps ensure the longevity of veneers and reduces the risk of cavities.

How to Prevent Cavities with Veneers

Maintaining oral hygiene is key when you have veneers. Recommended practices include:

  • Brushing twice daily: Use a soft-bristled toothbrush and fluoride toothpaste, paying special attention to the edges of veneers.
  • Flossing daily: Clean between teeth and along the gumline to prevent plaque build-up. Interdental brushes or floss threaders can be useful.
  • Using mouthwash: Fluoride or antibacterial mouthwashes can help strengthen enamel and reduce bacteria.
  • Regular dental check-ups: Routine visits allow dentists to inspect veneers and surrounding teeth for early signs of cavities or other issues.
  • Dietary considerations: Reducing sugary and acidic foods helps protect enamel around veneers.

At Freshdental in Bayswater, London, our clinicians provide guidance on caring for veneers to support both oral health and aesthetic results.

Signs of Cavities with Veneers

Even with veneers in place, cavities can develop on the natural teeth. Early detection is important to prevent further complications. Look out for the following:

  • Sensitivity to hot, cold, or sweet foods
  • Discomfort or pain when biting
  • Dark spots or discolouration near the edges of a veneer
  • Loose or chipped veneers

If any of these symptoms occur, it is important to seek dental advice promptly. Early intervention can prevent more extensive dental work.

Can Cavities Damage Veneers?

Untreated cavities can affect the integrity of a veneer over time. Decay near the edges or under the veneer may lead to weakening of the underlying tooth and potential veneer failure. Maintaining preventive care is essential to avoid compromising both the natural tooth and the veneer.

Veneers and Long-Term Oral Health

Veneers can provide a long-lasting improvement to your smile, but they do not replace natural oral care. To ensure both aesthetic results and dental health, consider the following:

  • Maintain regular brushing and flossing routines
  • Attend dental check-ups every six months
  • Avoid habits that could damage veneers, such as biting on hard objects
  • Monitor for early signs of decay or gum issues

By following these measures, veneers can continue to enhance your smile while supporting the health of your teeth.

Frequently Asked Questions

1. Can veneers prevent cavities?

No. Veneers protect only the front surface of the teeth. The underlying tooth and exposed surfaces are still susceptible to cavities.

2. Can teeth with veneers be whitened?

No. Veneers do not respond to whitening treatments. If you want a brighter smile, it is best to whiten natural teeth before placement.

3. Are cavities under veneers common?

Cavities under veneers are uncommon if the veneers are properly fitted and oral hygiene is maintained.

4. How often should I visit the dentist with veneers?

Routine dental check-ups every six months are recommended to monitor veneers and surrounding teeth for any early signs of decay.

Summary

Veneers are a reliable cosmetic solution to improve the appearance of teeth, but they do not make teeth immune to cavities. Proper oral hygiene, regular dental visits, and careful dietary habits remain essential to protect the natural teeth underneath and around veneers.

At Freshdental in Bayswater, London, our clinicians provide guidance on caring for veneers and maintaining long-term oral health. Whether you are considering veneers or already have them, following preventive practices can ensure both a healthy and aesthetically pleasing smile.
