How Long Do Dental Crowns Last?
How long do dental crowns last? Long-term studies of metal-ceramic crowns, the best-documented type, found that about 92% to 97% were still in service after 10 years and roughly 79% to 85% after 20 to 25 years. No study measures an exact lifespan, though. How long a crown lasts depends on the tooth underneath, gum health, bite forces and hygiene.
This guide covers tooth-supported crowns. Crowns on dental implants follow different evidence and are covered separately.
How Long Do Dental Crowns Last in Clinical Studies?
Crown studies report outcomes in a few different ways, and the terms are not interchangeable:
- Survival rate: the share of crowns still in the mouth at a given time, even if they needed minor repair.
- Failure rate: the share lost or replaced, for any reason.
- Success rate: the share that stayed in place with no complication or intervention at all. It is always lower than survival.
- Complication rate: how often a problem occurred, such as chipping or a loose crown.
Lifespan in years is an interpretation of these figures. It is not something a study measures for an individual patient.
Long-term survival evidence
The two systematic reviews pooled many studies with a statistical model to estimate 5-year survival. They do not report 10- or 20-year figures, and their 5-year numbers should not be stretched to longer periods. The 20- and 25-year results come from single practices, so they show what is possible with careful treatment rather than what every patient can expect. So how long do dental crowns last for most people? The evidence supports planning for well over a decade of service from a well-made crown on a healthy, well-maintained tooth, without a guarantee for any single crown.
Does the Crown Material Change How Long It Lasts?
Material choice matters less than many people expect when they ask how long do dental crowns last. Over 5 years, most modern materials perform similarly. A 2026 meta-analysis estimated comparable 5-year survival for metal-ceramic, zirconia and lithium disilicate crowns, while traditional feldspathic porcelain did worse. Long-term data beyond 10 years exist mainly for metal-ceramic crowns.

"Porcelain crown" is a loose term. It can mean an all-ceramic crown or a PFM crown, where porcelain is fused over a metal core. Our zirconia vs porcelain crowns guide compares the two in detail, and the separate article on how long zirconia crowns last covers that material's evidence.
What Affects How Long a Crown Lasts?
- The supporting tooth. In the 25-year Walton study, biological problems with the tooth or gums caused 101 of 133 failures. Material breakdown was rare.
- Gum health. Behr and colleagues recorded periodontitis around 14.4% of crowns, and its frequency rose with time in service and patient age.
- Decay at the margin. Recurrent decay was less common (1.3% of crowns), but it also became more frequent the longer crowns were in service.
- Root canal–treated teeth. Walton found lower overall survival for nonvital teeth than for vital teeth.
- Grinding and clenching. Bruxism was among the risk factors Behr investigated for chipping. Heavy forces can also loosen or fracture crowns.
- Position in the arch. In a 15-year molar crown study, crowns on the last tooth in a row had a 3.6-fold higher risk of complete failure than crowns with a tooth on each side.
What Problems Can Happen With Crowns?
Most crowns that fail do so because of the tooth, not the crown. Common problems include:
- Chipping of the porcelain layer. Found in 1.7% of metal-ceramic crowns in the Behr study, usually in the first few years.
- Loss of retention. The crown comes loose from the tooth. In the same study, 92.2% of front-tooth crowns and 97.1% of back-tooth crowns stayed free of this at 10 years.
- Decay or gum disease around the crown edge, which tends to appear later.
- Nerve problems in the tooth under the crown, which may need root canal treatment.
- Appearance concerns. In the Walton cohort, 22 crowns were replaced because patients were unhappy with their appearance, after a mean of 14 years.
How Can You Make a Crown Last Longer?
- Brush twice a day and clean between your teeth daily, paying attention to the gumline around the crown.
- Keep regular checkups so your dentist can spot early decay or gum changes at the margin.
- Ask about a night guard if you grind or clench.
- Avoid biting ice, hard candy, pens or bottle caps.
- Report a crown that feels high, rough or loose rather than waiting.
Signs a Crown May Need Replacing
- a crack, chip or visible fracture
- a crown that moves or has come off
- a gap or dark line where the crown meets the tooth
- pain, swelling or sensitivity to hot and cold
- gum recession exposing the crown margin
- a bite that suddenly feels different
Pain or swelling usually points to the tooth or gums and needs prompt attention.
Repair or Replacement?
It depends on what failed. A crown that comes off intact can sometimes be cemented back if the tooth is sound. A small chip in the porcelain may be polished or patched. A cracked crown, decay under the margin or a broken core usually means a new crown, and sometimes treatment of the tooth first. If the tooth cannot be saved, an implant may be considered; crowns on implants have their own evidence, covered in our guide to how long implant crowns last.
Dental Crowns at Novexdent
At Novexdent, crown treatment in Istanbul uses metal-free zirconia, hand color-matched to neighboring teeth, and E.max (lithium disilicate) for selected cases. The clinic notes that E.max is less strong than zirconia and may not suit back teeth. Crowns typically come with a 5-year guarantee, which is a service term, not a lifespan estimate. Patients who grind are advised to wear a night guard. You can read more about zirconium crowns turkey treatment, or send photos and X-rays for a free online consultation.
Frequently Asked Questions
Can a dental crown last a lifetime?
Some do. In one practice-based study, about 85% of well-placed metal-ceramic crowns were estimated to survive 25 years. Younger patients should still expect at least one replacement over time.
How long do dental crowns last on front vs back teeth?
In the Behr study, back-tooth metal-ceramic crowns had slightly higher 10-year survival than front-tooth crowns, but the difference was small. Walton found no significant difference by tooth position.
Is a crown guarantee the same as its lifespan?
No. A guarantee is a clinic's service commitment for a set period. It says nothing about how long a particular crown will actually last in your mouth.
Can the tooth under a crown still decay?
Yes. The crown cannot decay, but the natural tooth at its edge can. Daily cleaning at the gumline and regular checkups lower the risk.
Why did my crown fail after only a few years?
Early problems are often chipping, a loose crown or a bite issue. Later failures are more often linked to decay, gum disease or the tooth's nerve. A dentist needs to examine the tooth to find the cause.
