How long do veneers last, and what usually causes replacement?
Published follow-up studies report that most porcelain veneers are still in place after ten years, with a minority needing repair or replacement along the way. How long yours last depends on the tooth they are bonded to, your bite and grinding habits, how much of the veneer sits on enamel rather than old filling, and how the margins are kept clean.
No dentist can promise a number for an individual, and "lasting" usually includes some maintenance.
What survival means in a study
A veneer counts as surviving if it is still in place. It may have been repaired. Studies also count complications separately, so a chipped veneer that was polished is a complication, not a failure. Patients usually mean something stricter: still in place, still looking right.
What the studies report
| Study | Studied | Reported |
|---|---|---|
| Alenezi et al., J Clin Med 2021 | 25 studies, 6,500 porcelain veneers, 1,646 patients | Estimated 95.5% still in place at 10 years; fracture the most common complication, debonding second |
| Layton, Clarke & Walton, Int J Prosthodont 2012 | 6 cohort studies of feldspathic veneers | 95.7% pooled survival at 5 years; 10-year estimates ranged 64% to 96% across studies |
These are averages across many dentists and patients, reported here as study findings.
Common reasons veneers are replaced
- Fracture or chipping. Small chips may be polished or repaired; large ones mean replacement.
- Debonding. An intact veneer that comes off cleanly can sometimes be rebonded.
- Margin staining or discoloration. Surface stain polishes off; a dark line at the edge may mean a worn seal or decay beneath.
- Decay at the margin. Cavities can form under or around a veneer (ADA).
- Gum recession exposing the edge or root.
- Changing preferences about shade or shape.
Factors linked to higher risk in the evidence
Grinding, bonding to dentin or large fillings rather than enamel, and veneers that do not cover the biting edge were associated with more failures in the 2021 review.
What maintenance looks like
Daily cleaning at the margins with fluoride toothpaste and floss, routine checkups and x-rays, a guard where indicated, and not using teeth as tools (ADA).
What to ask before treatment
How are chips handled, and is there a charge? How often will the veneers be checked? Will I need a guard?

Evidence table: survival, repairs, replacement
| Term | What it means | What the cited studies reported | What affects it in your mouth | What you can do |
|---|---|---|---|---|
| Survival | Veneer still in place | ~95.5% at 10 years (Alenezi 2021); 95.7% at 5 years (Layton 2012) | Enamel under the veneer, bite, grinding | Keep margins clean; wear a guard if advised |
| Repair | Chip polished or bonded | Fracture was the most common complication (Alenezi 2021) | Edge design, habits | Don't bite hard objects |
| Replacement | New veneer made | A minority over 10 years (both reviews) | Decay, recession, large fracture | Checkups and x-rays |
| Follow-up | Routine checks | Not quantified | Risk level | Ask for a review schedule |
