can you get cavities with veneers


In this blog, we learn that veneers are thin covers for teeth that can fill gaps, change tooth shape, hide stains, and fix chipped or broken teeth. While veneers make smiles look better, they don’t prevent cavities or strengthen teeth. 

Cavities can still happen under veneers if oral hygiene isn’t maintained. Good oral care, including brushing, flossing, and regular dental visits, is crucial for both natural teeth and veneers to prevent decay. Following these tips can help maintain the appearance and health of veneers, ensuring a bright smile.

The porcelain used in your veneers won’t decay, but cavities can still form behind them. If this happens, the decay can harm your teeth and might make your veneers not last as long.

In this blog, we will discuss the following topics:

What Are Veneers?

Veneers are thin shells made of tooth-colored materials, such as porcelain or composite resin, that are custom-made to cover the front surface of teeth. They are designed to improve the appearance of teeth by changing their color, shape, size, or length. Veneers are commonly used to address various cosmetic dental issues, including:

  1. Discoloration: Veneers can effectively cover teeth that are stained or discolored and resistant to whitening treatments.
  2. Chips or Cracks: Veneers can conceal small chips, cracks, or fractures in teeth, restoring a more uniform appearance.
  3. Gaps or Spaces: Veneers can close gaps or spaces between teeth, creating a more even and symmetrical smile.
  4. Misalignment: Veneers can give the appearance of straighter teeth without the need for orthodontic treatment in cases of minor misalignment or irregularly shaped teeth.

The process of getting veneers typically involves several steps, including consultation, tooth preparation, impression-taking, fabrication of custom veneers, and bonding the veneers to the teeth using dental cement. Veneers are a popular cosmetic dental treatment due to their ability to produce dramatic results with minimal alteration to the natural teeth.

Can You Still Get Cavities With Porcelain Veneers?

Yes, you can still get cavities with porcelain veneers. While porcelain veneers themselves are resistant to decay and staining, the natural tooth structure underneath the veneers is still susceptible to cavities. It’s essential to maintain good oral hygiene habits, such as brushing and flossing regularly, to prevent decay from developing around the margins of the veneers where they meet the natural tooth.

Additionally, regular dental check-ups and cleanings are crucial for monitoring the health of both the veneers and the underlying teeth. Your dentist can detect any signs of decay early on and provide appropriate treatment to prevent further damage to your teeth and veneers.

Even though porcelain veneers can enhance the appearance of your smile, it’s important to continue practicing proper dental care to ensure the longevity and health of your teeth and veneers alike.

Why do cavities happen?

Your mouth has lots of bacteria, but brushing and flossing usually keep them in check. When bacteria mix with sugars in your food, they make acid that can harm your tooth’s outer layer (enamel). Saliva and fluoride in toothpaste can help repair this damage.

If the decay goes deeper to the next layer (dentin), it creates a deep cavity that hurts and makes your tooth sensitive. The fix for a cavity is a filling. Many people have had cavities—about 90% of adults aged 20 to 64, according to research.

Can veneers prevent cavities? Not exactly. Veneers are thin covers for the teeth’s front part. To put them on, some enamel is removed. While veneers can’t get cavities, the tooth under them can because some natural enamel is gone. Decay-causing bacteria and acids can get under the veneer, causing cavities if you don’t take care of your teeth well. That’s why if you have bad tooth decay or gum disease, veneers might not be a good idea.

How to care for your veneers—and teeth

  • Brush and floss daily with fluoride toothpaste and a soft brush.
  • Drink tap water with fluoride, not just bottled water.
  • Limit sugary and starchy foods and drinks like sodas, cookies, and chips.
  • Visit your dentist twice a year for cleaning and check-ups.

Veneers are mostly for looks and won’t shield you from cavities. You still need to care for your teeth to prevent decay.

5 Tips For Maintaining Your Veneers 

Taking care of your veneers is like caring for your natural teeth. Here are seven easy tips:

  • Practice Good Oral Hygiene: Brush your teeth at least twice a day with a soft-bristled toothbrush and fluoride toothpaste. Floss daily to remove plaque and debris from between your teeth and around the veneers. Maintaining good oral hygiene helps prevent decay and gum disease, which can affect the longevity of your veneers.
  • Avoid Staining Foods and Beverages: Certain foods and drinks, such as coffee, tea, red wine, and dark-colored sauces, can stain your veneers over time. Limit your consumption of these staining substances or rinse your mouth with water after consuming them to help minimize staining. Additionally, consider using a straw when drinking beverages that may stain.
  • Be Mindful of Habits: Avoid habits that can damage your veneers, such as biting your nails, chewing on hard objects like ice or pencils, or using your teeth to open packaging. These habits can chip, crack, or loosen your veneers, requiring repairs or replacements.
  • Protect Your Teeth During Sports: If you participate in sports or activities where there’s a risk of dental injury, wear a mouthguard to protect your veneers and natural teeth from trauma. A custom-fitted mouthguard, provided by your dentist, offers the best protection against impact.
  • Attend Regular Dental Check-ups: Visit your dentist for regular check-ups and cleanings to monitor the condition of your veneers and overall oral health. Your dentist can identify any issues with your veneers early on and provide appropriate treatment to maintain their appearance and function.

By following these tips and practicing proper dental care, you can help ensure the longevity and durability of your veneers for years to come.


In conclusion, while porcelain veneers themselves are resistant to decay, cavities can still develop on the natural tooth structure beneath them. Maintaining good oral hygiene practices, attending regular dental check-ups, and addressing any signs of decay promptly are essential for preserving the health and longevity of both the veneers and the underlying teeth. By following these guidelines, individuals can enjoy the aesthetic benefits of veneers while minimizing the risk of dental issues such as cavities.
