Why Veneer Lifespan Numbers Don't Agree

Look up how long veneers last and you will find numbers from 53 percent to 99 percent. Most of them are real. They disagree because they measure different things, in different hands, on different teeth, over different lengths of time. Once you see which is which, they tell you what to ask about your veneers.

Short answer

Veneer studies disagree mostly because they count different things. Veneers bonded to enamel had about 99 percent survival in one review,1 while in routine UK practice only about 53 percent of veneered teeth went 10 years with no further treatment.2 The definition of failure, who placed the veneers, how much enamel was left, how many patients grind and how long the study ran explain most of the gap.

Highest figure99% survival, veneers bonded to enamel
Lowest figure53% with no re-treatment in 10 years, routine UK practice
Same veneers, two scores94% still in place, 70% never repaired
GrindingAbout 7.7 times the failure risk

The range: from 53 to 99 percent

Published veneer figures run from about 53 percent to about 99 percent, and each one answers a slightly different question.

Read the middle column first. That is where the disagreement comes from.

None of these is wrong. Five differences explain most of the spread, and each gets a section below: what counts as failure, who placed the veneers, what they are bonded to, who the patients are, and how long the study ran.

Survival vs success

The same veneers scored 94 percent on survival and 70 percent on success, because the two words measure different things.1

Survival means the veneer is still in the mouth, even if it was chipped and repaired or came off and was bonded back on. Success means it never needed anything. Survival always looks better, even on the same teeth. In the review above, veneers bonded over old fillings were 94 percent still in place but only 70 percent untouched. That gap is pure definition.

A practice that tracked 1,459 veneers for 10 years shows it as a yearly rate. Ceramic veneers failed at about 1.2 percent per year by the survival measure and about 2.8 percent per year by the success measure. For composite it was 4.1 versus 10 percent.8 Overall, about 66 percent never needed a repair, 17 percent were repaired and kept, and 17 percent were replaced.8

Material comparisons hide the same split. Lithium disilicate (e.max type) and feldspathic porcelain had nearly the same survival at about 10 years, roughly 97 and 96 percent. But technical problems such as chipping showed up in about 6 percent of the lithium disilicate veneers and about 41 percent of the feldspathic ones.9

Survival tells you how likely you are to need a new veneer. Success tells you how much upkeep to expect. Ask for both.

Study clinics vs everyday practice

University clinics and single expert practices report about 94 to 96 percent at 10 years, while routine UK practice found about 53 percent with no further treatment.2,3,6

Most veneer research comes from places that do a lot of veneers and choose cases carefully. In one prosthodontist's 20-year series, preparations kept at least 80 percent enamel and teeth without a living nerve were left out. Survival was about 96 percent at 10 years and 91 percent at 20.3 Good habits, and also a favorable study group. The big pooled reviews lean on this kind of data.4

At the other end, a study of 2,562 veneers in 1,177 adults in England and Wales found about 53 percent of veneered teeth went 10 years without further treatment.2 Two cautions before comparing it head to head:

  • It counted any later treatment on the tooth, even a small filling beside a veneer that was fine. It does not mean the other half of the veneers broke.
  • The authors found patient factors, more than dentist factors, drove the differences.

Still, the gap is real. A veneer placed with careful case selection, plenty of enamel and close follow-up is not the same as one placed with little time for planning. Ask your dentist how they plan veneers, not only which material they use.

Enamel vs dentin

Veneers bonded to enamel had about 99 percent survival and success, falling to about 91 percent survival and 74 percent success when a lot of dentin was exposed.1

Enamel is the hard outer layer, and bonds to it are strong and predictable. Dentin, underneath, is softer and wetter, and bonds to it are less reliable. How much enamel is left depends mostly on how much tooth is removed. With only minimal dentin exposure, survival and success were both about 95 percent.1

The older reviews show the same thing. At 10 years, feldspathic veneer results ranged from 64 to 95 percent across studies, with the best estimate near 95 percent when veneers were bonded to enamel.7

And preparations vary widely. In a lab study on model teeth, veneer preparations removed about 3 to 30 percent of the crown of the tooth by weight10. A thin enamel veneer and a deep one into dentin are both called "a veneer," but they will not perform the same. See how much tooth is removed for veneers and the teeth under veneers.

Grinding and other patient factors

People who grind or clench had about 7.7 times the risk of veneer failure, so a study full of grinders reports lower numbers than one that left them out.6

The Innsbruck study is useful because half of its 84 patients had bruxism, far more than most study groups.

  • Grinding or clenching7.7×

    The biggest risk in that study. Groups with few grinders, or many night-guard wearers, look better.6

  • Teeth without a living nerveHigher risk

    Veneers on teeth that had lost their nerve (nonvital teeth) failed significantly more often in a 20-year study6. The expert-practice series above excluded them.

  • SmokingMore staining

    Smokers had more staining at the veneer edges.6 Not a failure, but it can count against "success."

So the first question about any study is whether its patients look like you. If you grind, the grinders' numbers apply to you, and a night guard is part of the plan.

Follow-up length

The same clinic estimated about 94 percent survival at 5 years and about 83 percent at 20, because a longer study gives more time for something to go wrong.6

That study's average follow-up was about 10 years, so its 20-year figure rests on fewer veneers. The further a survival curve goes, the fewer patients are still being counted.

Five-year numbers look best. One review put feldspathic veneers at about 96 percent at 5 years, but only three studies had 10-year data, ranging from 64 to 95 percent.7

Very short studies can make a new material look perfect. Zirconia veneers had no failures, but the studies lasted only about 2.6 years.9 That is good news, and it says nothing yet about year 15. Check how long any "longer lasting" material has actually been studied. Our materials comparison lists follow-up times.

A worked example: wrapping the biting edge

Three reviews asked whether a veneer should wrap over the biting edge and got three different answers.

ReviewFindingWhy it may differ
Alenezi 2021In a 2021 review, veneers that wrapped over the biting edge failed less often than veneers that did not4.Largest data set: 25 studies, 6,500 veneers
Hong 2017A 2017 review reached the opposite conclusion, finding that veneers covering the biting edge had about 1.8 times the failure risk in one type of analysis11.10 studies. A second method on the same data found no significant difference.
Morimoto 2016A third review found no clear effect of covering the biting edge, with a wide range of uncertainty5.13 studies; uncertainty too wide to call

Run it through the checklist below and the split makes sense. The reviews used different studies and different statistics, and Hong's answer changed with the method. None of the original studies assigned edge coverage at random. Dentists tend to wrap edges on teeth that are already worn, chipped or being lengthened, which are harder cases to start with, and that alone can make wrapped veneers look worse.

The research is split on whether a veneer should wrap over the biting edge. My approach is to wrap it. Wrapping the edge lets the ceramist control the length and translucency of the tip, a big part of what makes a veneer look natural.

How to read a lifespan claim

Before trusting any veneer lifespan number, ask what it counted, over how long, in whose hands, and in what kind of patients.

  1. Is there a source? "10 to 15 years" with no study behind it is a guess.
  2. Survival or success? Still in the mouth, or never repaired?
  3. After how many years? And how many veneers were still being followed by then?
  4. Who placed them? A university clinic, one expert practice, or everyday care?
  5. Enamel or dentin? Ask how much tooth your dentist plans to remove.
  6. Who were the patients? Were grinders and root-canal teeth included?
  7. Which material, studied for how long? New materials have short track records.
  8. What counted as failure? A broken veneer, or any later treatment on the tooth?

These work on a dentist's own claims too, including mine.

What this means for your veneers

What puts veneers at the top of the research range is mostly in your and your dentist's control: enamel, grinding protection, case selection and upkeep.

A well-planned porcelain veneer, bonded mostly to enamel, on a healthy tooth, in someone who wears a night guard if they grind, has the odds of the top rows of the table. A deep preparation into dentin on a heavy grinder without a guard has the odds of the bottom rows. That is why I start with a mock-up in your mouth before any preparation and keep the preparation small. Full numbers are in how long veneers last and porcelain vs composite veneers.

When veneers may not be the right choice: if the only problem is color, whitening leaves the tooth untouched. Crooked but healthy teeth may do better with clear aligners. One chip or gap may need only bonding. If the look would require removing most of the enamel, a crown or another plan may serve the tooth better. If veneers you have now are failing, see veneer replacement and redos.

Want the high end of those numbers?What puts veneers at the top of the research range is mostly planning: keeping enamel, a mock-up before any preparation, and protection from grinding. See how Dr. Henley plans veneers in Jacksonville.

Questions about veneer success and failure rates

How long do veneers really last?

In the large reviews, about 89 to 96 percent of porcelain veneers are still in place at 9 to 10 years,4,5 and long studies put 20-year survival at about 83 to 91 percent.3,6 Everyday practice runs lower. Details: how long veneers last.

What is the failure rate of veneers?

It depends on the definition. In one practice over 10 years, ceramic veneers failed at about 1.2 percent per year and composite at about 4.1 percent. Counting repairs too, the rates were about 2.8 and 10 percent.8

What is the success rate of veneers?

Success usually means never needing a repair. It was about 99 percent for veneers on enamel, about 74 percent with a lot of exposed dentin, and about 70 percent over old fillings.1

Why do some websites say 5 to 10 years and others say 20?

Most of those ranges have no source. Short ranges often reflect composite or routine-practice data. Twenty-year figures usually come from one clinic or expert practice that followed patients for decades.

What is the most common reason veneers fail?

A chip or crack in the porcelain. It caused about 45 percent of failures in a 20-year study.6 Coming loose is next.4

Do veneers fail more often in people who grind?

Yes, about 7.7 times as often in one 20-year study.6 A night guard is the usual protection.

Are e.max veneers more reliable than other porcelain?

They stay in place at about the same rate as feldspathic porcelain, but had far fewer problems along the way: about 6 percent versus 41 percent at about 10 years.9

Does a 20-year number mean my veneers will last 20 years?

No. It is the share still in place in that study, often based on fewer veneers than the 10-year figure.6 Your odds depend on your bite, your enamel and your habits.

How can I tell if a lifespan claim is reliable?

Ask: survival or success, over how many years, from what kind of practice, on enamel or dentin, and in patients like you? A number with no source is a sales line.
