If you have porcelain veneers or are considering them, you may wonder: Can veneers get cavities? The short answer is no. Porcelain veneers themselves cannot develop cavities because porcelain does not decay.
However, you can still get cavities if you have veneers. Veneers cover the front surface of a natural tooth, but they do not completely cover or replace the entire tooth. The natural tooth underneath and around the veneer can still be affected by tooth decay.
Understanding how cavities can develop with veneers and how to prevent them can help you protect both your veneers and your natural teeth for years to come.
Can You Get Cavities If You Have Veneers?
Yes. Having veneers does not make you immune to cavities.
A porcelain veneer is bonded to the front surface of your natural tooth. While the veneer itself is resistant to decay, the natural tooth remains underneath it. Areas of exposed natural tooth, particularly around the edges of a veneer and near the gumline, can still develop cavities.
This is one reason maintaining good oral hygiene is just as important after getting veneers as it was before treatment.
Can You Get Cavities Under Veneers?
Yes, a cavity can develop in the natural tooth underneath or around a veneer.
It is important to understand that a veneer does not cover every part of a tooth. Porcelain veneers are thin restorations designed primarily to cover the visible front surface of the tooth. The back, sides, and portions of the tooth near the gumline may remain natural tooth structure.
If bacteria and plaque accumulate in these areas, tooth decay can develop.
A cavity doesn’t necessarily form directly underneath the porcelain itself. Instead, decay can occur in the natural tooth structure that remains exposed or along the margins where the veneer meets the tooth.
Why Can Cavities Develop Around Veneers?
Cavities form when bacteria in dental plaque interact with sugars and carbohydrates in the foods and drinks you consume. This produces acids that can gradually weaken tooth enamel and cause decay.
Veneers don’t change this process.
Several factors can increase the risk of decay around veneers, including:
- Inadequate brushing or flossing
- Plaque buildup around the gumline
- Frequent consumption of sugary foods and drinks
- Not cleaning between teeth
- Gum recession that exposes additional natural tooth structure
- Existing decay that was not properly addressed before veneer treatment
The margins of a veneer, where the porcelain meets the natural tooth, are particularly important to keep clean.
How Do You Know If You Have a Cavity Under a Veneer?
A cavity may not always cause noticeable symptoms in its early stages. You might not know there is a problem until your dentist examines the tooth.
Possible signs of tooth decay can include:
- Tooth sensitivity to hot or cold
- Sensitivity to sweets
- Tooth pain
- Discomfort when biting
- A dark spot or discoloration near the veneer
- Changes around the gumline
- An unpleasant taste or odor around a particular tooth
However, the absence of symptoms does not necessarily mean that a tooth is free of decay. Regular dental examinations allow your dentist to check the teeth supporting your veneers and monitor the areas around the veneer margins.
Can a Cavity Under a Veneer Be Treated?
If decay develops in a tooth with a veneer, treatment depends on the location and extent of the decay.
In some cases, the dentist may be able to treat a small area of decay without removing the veneer. In other situations, accessing the affected area may require removing and replacing the veneer.
The appropriate treatment depends on the individual tooth, the location of the cavity, and how much healthy tooth structure remains. This is one reason careful planning and regular dental care are important for anyone with veneers.
How Can You Prevent Cavities With Veneers?
Taking care of your natural teeth is essential for maintaining your oral health and protecting your investment in veneers.
Brush twice a day
Brush your teeth twice daily. Pay particular attention to the gumline and the areas where your veneers meet your natural teeth.
Floss every day
Flossing removes plaque and food particles from areas your toothbrush cannot reach, including between teeth and around the edges of veneers.
Limit frequent sugar exposure
Frequent exposure to sugary foods and drinks can increase your risk of tooth decay. Limiting sugary snacks and drinks throughout the day can help protect your natural teeth.
Keep up with regular dental visits
Regular examinations and professional cleanings allow your dentist to monitor your oral health and identify potential problems before they become more serious.
Follow your dentist’s recommendations
Your dentist can recommend an appropriate oral hygiene routine based on your teeth, gums, veneers, and overall oral health. Read our Caring for Veneers Guide to learn more.
Do Veneers Protect Your Teeth From Cavities?
Porcelain veneers can provide a durable covering over the front surface of a tooth, but they should not be considered protection against cavities. The natural tooth remains susceptible to decay wherever it is exposed. Veneers also do not replace regular brushing, flossing, fluoride use, or professional dental care. Think of veneers as a cosmetic restoration, not a substitute for maintaining healthy teeth and gums.
Protecting Your Smile After Veneers
Porcelain veneers are designed to improve the appearance of your smile while preserving as much healthy tooth structure as appropriate. Maintaining the health of the natural teeth underneath and around your veneers is an important part of achieving long-lasting results.
If you have veneers and are experiencing sensitivity, pain, or changes around a veneer, schedule an examination with your dentist. Early evaluation can help identify decay or other dental problems before they become more extensive.
