People get veneers to cover dental issues such as discoloration, cracks, and gaps. Although veneers themselves are resistant to tooth decay, the natural tooth structure beneath them remains susceptible to cavities. So, yes, you can still get cavities with veneers!

Read more to find out the causes and signs of cavities under veneers and how you can manage them.

What Causes Cavities Under Veneers?

Cavities under veneers can be caused by the following reasons:

  • Plaque and tartar buildup
  • Poor oral hygiene
  • Pre-existing cavities
  • Worn or damaged veneers
  • Excessive sugar intake
  • Excessive tobacco use

Signs You Are Developing Decay Under Veneers

If you notice any of these signs, your teeth may be developing cavities under the veneers:

  • The tooth feels sensitive or sore
  • Loose tooth or veneer
  • Tooth sensitivity to hot and cold
  • The tooth is sensitive to pressure
  • Gum soreness
  • Infection on gum or tooth

If you experience any of these symptoms, contact your dentist right away. If decay is present, the veneer may need to be removed so the dentist can treat the tooth.

How Do Cavities Develop Under Veneers?

Veneers are made from materials like porcelain or composite resin, which are strong and resistant to tooth decay.

These materials don’t have tiny spaces where bacteria can build up and cause cavities.

However, veneers only cover the front of your teeth, so the sides and back are still exposed. This means plaque and bacteria can still build up in these areas and lead to cavities.

If you already have cavities before getting veneers, they need to be treated first. Veneers can’t be placed over existing decay, as the problem will continue to worsen underneath the veneer, leading to more serious dental issues.

How To Protect Teeth Under Veneers?

To keep your teeth and veneers healthy, follow these tips:

  • Practice Good Oral Hygiene
    Brush your teeth twice a day with prescribed toothpaste and floss daily to remove plaque and food. Use an antibacterial mouthwash to prevent buildup on gums.
  • Get Regular Dental Check-Ups
    Veneers can experience damage in the form of decay. In order to prevent that, visit your dentist every six months to check the health of your veneers and teeth beneath them.
  • Limit Sugary and Acidic Foods
    Mindful choices about what things to eat can prevent cavities under veneers. Cut back on sugary and acidic foods like chewing gum, coffee or sodas.
  • Use a Mouthguard
    Wear a mouthguard if you grind your teeth or play sports to protect both your natural teeth and veneers.
  • Limit Tobacco Use
    Excessive tobacco use can contribute to gum disease, affecting veneer support and teeth health. It is best to limit its use for preserving veneer and tooth function.

Overall Insight

Yes, you can still get cavities with veneers. While the veneers themselves are resistant to decay, the parts of your teeth that are not covered, like the sides and back, can still develop cavities. It’s important to maintain good oral hygiene and visit your dentist regularly to keep both your veneers and natural teeth healthy.
