How Long Do Dental Crowns Last? Lifespan by Material and How to Make Them Last
By Naomi Foster, Contributing Writer, Healthcare
Updated 2026-07-08
Dental crowns last 10 to 15 years on average, with gold or zirconia crowns often lasting 20 to 30 years under good conditions. Material, tooth location, bite habits, and oral hygiene all affect lifespan. The most common reasons crowns fail before their time are decay at the gumline margin, grinding or clenching that chips ceramic, and cement washing out over time.

How long do dental crowns last?
The average crown lasts 10 to 15 years under normal conditions, with many lasting considerably longer depending on the material, the tooth's location, your bite habits, and how well you care for your teeth. Some gold crowns have been documented lasting 25 to 30 years or more. Understanding the lifespan of different crown materials helps you weigh the long-term value of the investment you are making today.
Lifespan by material
| Material | Average lifespan | Failure risk |
|---|---|---|
| Gold or high-noble metal | 20 to 30 or more years | Very low; gold is extremely durable |
| Monolithic zirconia | 15 to 25 years | Low; tough material, no porcelain to chip |
| PFM (porcelain-fused-to-metal) | 10 to 15 years | Moderate; porcelain can chip off metal base |
| All-ceramic or all-porcelain | 10 to 15 years | Moderate; brittle under heavy bite forces |
| Layered zirconia | 12 to 18 years | Low to moderate; porcelain layer can chip |
| Same-day CEREC ceramic | 10 to 15 years | Similar to conventional ceramic |
Why crowns fail before their time
The most common reasons a crown fails earlier than expected include decay at the margin where the crown meets the natural tooth at the gumline (bacteria working their way under the crown), grinding or clenching that puts enormous cyclic stress on crowns over time, chipping of porcelain layers in patients with heavy bite forces, cement washing out and leaving the crown loose, and root problems in an already-crowned tooth that may require extraction. Most of these failure modes are either preventable with good oral hygiene and a nightguard, or detectable early with regular dental visits.
Some crowns, particularly well-maintained gold crowns on properly-prepared teeth, do last 30 or more years, though no dentist or manufacturer guarantees a lifetime lifespan for any crown material. Most patients should plan for eventual replacement after 10 to 20 years, with the actual number depending on the factors above and regular checkups catching problems early.
How to make your crown last longer
- Brush twice daily and floss once daily, paying attention to the gumline around the crown where decay most commonly starts.
- Use a nightguard if you grind or clench, especially for ceramic crowns on back teeth. Grinding is the single biggest preventable cause of premature crown failure.
- Avoid using crowned teeth to open packages, crack nuts, or bite fingernails, which applies force in directions the crown is not designed for.
- Attend regular dental checkups every 6 months so your dentist can catch early signs of decay at the margin or a loosening crown before they require full replacement.
- Tell your dentist if you notice any sensitivity to temperature or biting pressure, since these can be early signs that the crown or underlying tooth needs attention.
Replacing vs repairing a crown
Signs a crown needs attention include pain or sensitivity, visible cracking or chipping, a dark line at the gumline where old PFM metal shows through as gums recede, or decay at the margin found on an X-ray. Minor porcelain chips can sometimes be polished smooth or repaired with composite resin, but decay under the crown, significant structural damage, or a poor fit usually calls for replacement rather than repair. Replacement crowns cost roughly the same as the original, since the procedure involves the same preparation and fabrication steps; new decay found underneath can add preparatory cost on top. Talk to a licensed dentist to decide between repair and replacement rather than choosing based on cost alone.
FAQs
Is it normal for a crown to feel a little different than my natural tooth?
A slight difference in texture or temperature sensation is common at first and usually fades within a couple of weeks as you get used to it. A persistent difference in how your bite feels, on the other hand, is worth a follow-up visit.
Does the tooth underneath a crown still need a filling or a root canal later?
Yes, it can. A crown protects the outside of the tooth, but decay can still reach the tooth structure underneath through the margin, and a tooth that was healthy when crowned can still later need a root canal if the nerve becomes irritated or infected.
Can a cracked crown be fixed without replacing it?
Small chips in porcelain can sometimes be smoothed or patched with composite resin in a single visit. A crack that goes through the crown or exposes the tooth underneath usually means the whole crown needs to be replaced.
Does insurance cover a crown that fails early?
Most insurers require you to wait out a replacement interval, typically 5 to 7 years, before covering a new crown on the same tooth, unless you can show the original crown failed due to a manufacturing or fitting defect rather than normal wear.
Is it worth paying more for a longer-lasting crown material?
Often yes, if you plan to keep the tooth long term. A gold or zirconia crown costs more upfront but can outlast two or three cheaper crowns over the same span of years, which can make the cost-per-year lower even though the initial bill is higher.
Bottom line
With proper care, dental crowns typically last 10 to 15 years, and gold or zirconia crowns often exceed that. Good oral hygiene, nightguard use if you grind, and regular dental checkups are the most reliable ways to extend your crown's life.
