Replacing a veneer means removing the old one and bonding a new shell to your tooth
When a veneer cracks, stains, or comes loose, your dentist removes it by grinding it away, then prepares the tooth underneath and bonds a fresh veneer in its place. The process is similar to the original placement, but the tooth may need less preparation because some of the original shaping is already done. Most replacements take one or two appointments, depending on whether your dentist makes the veneer in-office or sends it to a lab.
The tooth under the old veneer is usually still intact—veneers are bonded to the surface rather than anchored into the tooth structure. This means the underlying tooth often needs only minor reshaping before the new veneer goes on. If the tooth has decay or damage underneath, your dentist will address that first.
Key Takeaways
- Your dentist removes the old veneer by grinding it away, then cleans and prepares the tooth surface for a new bond.
- The underlying tooth is usually still healthy and requires less preparation than the original veneer did.
- In-office veneers (made from composite resin) are ready the same day; lab veneers (made from porcelain) require a second appointment a week or two later.
- Replacement veneers cost less than original veneers because the tooth is already shaped, though prices vary by dentist and material.
- If a veneer comes loose but is not damaged, your dentist may be able to re-bond it without making a new one.
How your dentist removes the old veneer
Your dentist uses a high-speed drill or grinding tool to carefully wear away the veneer material. This takes 10 to 20 minutes depending on how thick the veneer is and how well it is bonded. The goal is to remove the veneer without damaging the tooth underneath, though some minor roughness is normal and will be smoothed during preparation.
Once the veneer is gone, your dentist cleans away any remaining bonding cement and examines the tooth for cracks, decay, or other damage. If the tooth is sound, preparation for the new veneer begins right away. If there is decay or a chip, that gets treated first—usually with a filling—before the new veneer is placed.
Preparing the tooth for a new veneer
Preparation for a replacement veneer is often gentler than for an original one, because the tooth has already been shaped. Your dentist may only need to lightly reshape the edges and surface to create a clean bond site. If the original veneer was very thin or the tooth has shifted, more shaping might be needed.
Your dentist will take an impression or digital scan of the prepared tooth. If you are getting a composite veneer made in the office, this scan helps guide the shaping of the new veneer. If you are getting a porcelain veneer from a lab, the scan is sent to the lab so the technician can match the shade and shape of your original veneer or create a new design if you want one.
Same-day composite veneers versus lab-made porcelain veneers
Composite veneers are made from tooth-colored resin that your dentist shapes and hardens with a light during your appointment. The whole process—removal, preparation, and placement—takes two to three hours. You walk out with your new veneer the same day. Composite veneers are less expensive than porcelain but are more prone to staining and chipping over time.
Porcelain veneers are made in a dental lab and require two appointments. At the first visit, your dentist removes the old veneer, prepares the tooth, and takes an impression. You wear a temporary veneer for one to two weeks while the lab makes the permanent one. At the second appointment, the temporary comes off and the new porcelain veneer is bonded on. Porcelain veneers are more durable and resist staining better than composite, but they cost more and take longer.
What to expect during the bonding step
Once your tooth is prepared, your dentist applies a bonding agent to the surface, then positions the new veneer and checks the fit and shade in natural light. You will have a chance to see how it looks before the final bond is set. If the shade or shape is not quite right, your dentist can adjust it—this is easier with composite veneers, which can be shaped in the chair, than with porcelain, which cannot be altered once it leaves the lab.
After you approve the look, your dentist applies a strong adhesive to the back of the veneer and presses it onto your tooth. A special light hardens the adhesive in seconds. Any excess cement is cleaned away, and your dentist checks your bite to make sure the veneer does not interfere with how your teeth come together when you chew.
Cost and timeline for veneer replacement
Replacement veneers usually cost less than original veneers because the tooth is already shaped and less preparation is needed. Costs vary widely by dentist, location, and material—composite replacements typically run $400 to $800 per tooth, while porcelain replacements run $800 to $2,000 per tooth. Some dental insurance plans cover a portion of veneer replacement if the veneer failed due to a defect rather than wear or damage, but coverage is uncommon and varies by plan.
The timeline depends on the type of veneer. Composite veneers are finished in one appointment. Porcelain veneers require two appointments spaced one to two weeks apart. If your dentist needs to treat decay or damage under the old veneer, add one or two extra days for that work to be completed before the new veneer is placed.
When a veneer can be re-bonded instead of replaced
If your veneer comes loose but is not cracked or stained, your dentist may be able to clean off the old bonding cement and re-bond the same veneer to your tooth. This is faster and cheaper than replacement and takes about 30 minutes. Your dentist will examine the veneer for damage and the tooth for decay before deciding whether re-bonding is safe.
Re-bonding works best if the veneer is still in good condition and came loose because the bonding cement failed, not because the veneer itself is damaged. If the veneer is cracked, severely stained, or has been loose for a long time, replacement is usually the better choice because a re-bonded veneer may fail again soon.
Caring for your new veneer
New veneers need the same care as your natural teeth: brush twice a day with a soft toothbrush, floss daily, and avoid biting hard objects like ice, hard candy, or pen caps. Veneers are durable but not indestructible, and a crack or chip means replacement.
Composite veneers may stain from coffee, tea, red wine, or tobacco, so rinse your mouth after consuming these. Porcelain veneers resist staining much better. Both types can last 10 to 15 years or longer with good care, though composite veneers often need replacement sooner because they are softer and more prone to wear.
Frequently Asked Questions
Can I get a veneer replaced if the tooth underneath has decay?
Yes. Your dentist will treat the decay with a filling first, then prepare the tooth and place the new veneer. If the decay is deep or close to the nerve, a root canal may be needed before the veneer is placed. This adds time and cost but protects the tooth.
How long does it take to replace one veneer?
Composite veneer replacement takes two to three hours in one appointment. Porcelain veneer replacement takes 30 to 45 minutes at the first appointment (preparation and temporary veneer) and 30 to 45 minutes at the second appointment (permanent veneer placement), with one to two weeks between visits.
Will my new veneer match my old one?
Your dentist will try to match the original shade and shape, but exact matching is not always possible because tooth color changes over time and lab techniques vary. If you want a different look, this is a good time to discuss changes with your dentist before the new veneer is made.
What happens if a veneer replacement fails?
If a replacement veneer comes loose, cracks, or stains within a short time, tell your dentist. Many dentists will re-do the work at no charge if the failure is due to a defect in their work rather than damage or wear on your part. Ask about any warranty when you have the veneer placed.
Is veneer replacement covered by dental insurance?
Most dental insurance does not cover veneers because they are considered cosmetic. Some plans cover replacement if the veneer failed due to a manufacturing defect within a certain time frame. Check your plan details or ask your dentist's office to contact your insurance company before the procedure.
