What Happens to Teeth Under Veneers?

Published on: June 13, 2025

At Smoke Rise Dental in Stone Mountain, GA, many patients love the instant transformation veneers provide, but also worry:

“What happens to my teeth under the veneers?”

Veneers are a powerful cosmetic tool that involves altering natural teeth and bonding a permanent shell on top. So, it is natural to ask whether those teeth remain healthy or become vulnerable.

In this blog, you’ll learn:

  • What the veneer prep process involves
  • How veneers impact the natural tooth underneath
  • What can go wrong if veneers aren’t cared for
  • Tips for preserving your dental health
  • And how Dr. Hassan Moeti and the team at Smoke Rise Dental ensure your veneers and your teeth last

What Are Veneers and How Are They Placed?

Dental veneers are thin porcelain or composite shells designed to cover the front surface of teeth. They improve the shape, size, alignment, and color of teeth, making them perfect for smile makeovers

Veneer Preparation Process

To place veneers, your dentist must:

  1. Trim a thin layer of enamel from the front of the teeth
  2. Take an impression or digital scan
  3. Bond the veneer using dental adhesive

This means that veneers are irreversible once you’ve had enamel removed. Your teeth will always need protection going forward, typically in the form of a veneer or crown.

What Happens to Natural Teeth Under Veneers?

The teeth underneath your veneers still require daily care and regular dental checkups. Here’s what’s happening beneath the surface:

1. Enamel Is Permanently Reduced

A small layer of enamel, usually about 0.5 mm, is removed to ensure the veneer fits naturally. This thinner enamel cannot grow back, and if the veneer comes off, it may expose your teeth to temperature sensitivity and damage.

2. Teeth Can Still Decay

Veneers cover only the front of the tooth, not the back, sides, or gumline. If you don’t brush and floss daily, plaque can accumulate, especially around the edges, leading to cavities and decay in the exposed areas.

According to the National Institute of Dental and Craniofacial Research:

Tooth decay begins when bacteria in your mouth make acids that attack the tooth’s surface (enamel). This can lead to a small hole in a tooth, called a cavity. If tooth decay is not treated, it can cause pain, infection, and even tooth loss.

3. Gum Health Still Matters

Inflamed or receding gums can expose the veneer margin or loosen the adhesive bond. This can cause aesthetic issues, potential tooth sensitivity, and perio-related veneer failure.

4. The Bond Between Veneer and Tooth May Weaken

Over time, the bonding material may deteriorate if you consume acidic or abrasive foods or use alcohol-based mouthwash. It weakens the veneer and enamel seal, increasing the risk of bacteria entering and causing decay.

What Happens If a Veneer Falls Off?

If a veneer comes loose due to trauma, decay, or age, the exposed tooth underneath may be:

  • Discolored due to limited enamel
  • Sensitive to hot, cold, or air
  • Structurally weak, increasing the risk of cracks or wear

In such cases, the tooth will need prompt restoration, either by re-bonding the veneer or placing a crown, depending on the damage.

How to Protect the Tooth Under Your Veneers

Maintaining the health of your veneered teeth is essential for longevity and appearance. Here’s how:

Brush with a Soft-Bristled Brush Twice Daily

Use a soft-bristled toothbrush and fluoride toothpaste to gently clean veneer surfaces without scratching them. Brushing twice daily removes plaque around the veneer margins, prevents gum inflammation, and protects the underlying tooth from decay, essential for maintaining oral health and veneer longevity.

Floss Every Day

Daily flossing removes plaque and food particles between teeth and near the gum line, helping prevent cavities and gum disease. It’s a critical step many overlook, yet it ensures your veneers and gums stay clean, healthy, and free from harmful bacterial buildup.

Use Alcohol-Free Mouthwash

Choose an alcohol-free mouthwash to keep your mouth fresh without harming veneer adhesives. Alcohol can weaken bonding materials over time and cause dryness, which may lead to irritation or sensitivity. A gentle rinse helps preserve your restoration’s seal and supports oral hygiene.

Avoid Grinding or Biting Hard Objects

Chewing on hard items like ice, pens, or fingernails can crack or dislodge veneers and damage the tooth beneath. If you grind your teeth at night, ask your dentist about a custom night guard to protect your restorations and natural teeth from excessive wear and tear.

Visit Your Dentist Regularly

Routine dental checkups every six months allow your dentist to assess veneer fit and bonding strength and detect early signs of decay or gum issues. Preventive visits ensure your veneers stay in excellent shape and address any concerns before they become costly or painful.

FAQs

Do veneers damage your natural teeth?

No, veneers don’t damage teeth when done correctly. However, enamel is permanently reduced, so the tooth must always remain covered.

Can you get cavities under veneers?

Yes. Cavities can form around the edges or on uncovered parts of the tooth if oral hygiene is poor.

What should I do if my veneer feels loose?

See your dentist immediately. A loose veneer can allow bacteria to enter and may require rebonding or replacement.

How long do veneers typically last?

With good care, veneers can last 10 to 15 years or longer. Regular cleanings and daily brushing help extend their life.

Will I feel pain in the tooth under a veneer?

You shouldn’t, but if you experience sensitivity or pain, it could signal decay, bonding failure, or gum issues. Don’t ignore it, get it checked promptly.
