If you just got a crown or are weighing one, a fair question is how long do dental crowns last. The short answer: usually five to 15 years, and often much longer with good care. Here is what to expect and how to get the most out of yours.
How Long Do Dental Crowns Last on Average?
Most crowns last between five and 15 years, and according to the Cleveland Clinic, a well-cared-for crown can last upwards of 30 years. The material makes a real difference: metal crowns tend to last the longest, while all-resin crowns are the most affordable but wear out fastest.
What Affects How Long a Crown Lasts
Two identical crowns can have very different lifespans depending on:
- Material. Metal and zirconia are the most durable; resin is the least.
- Your oral hygiene. Decay can still start where the crown meets the gumline, so brushing and flossing matter.
- Grinding and clenching. Constant force wears crowns down and can crack them.
- Location. Back molars do the heavy chewing, so they take more wear than front teeth.
- Habits. Chewing ice, hard candy, or using teeth as tools shortens a crown’s life.
How to Make Your Crown Last Longer
You have a lot of control over the lifespan:
- Brush twice a day and floss daily, paying attention to the crown’s edge.
- Wear a night guard if you grind your teeth.
- Avoid ice, hard nuts, and sticky candy that can crack or pull at the crown.
- Keep up with regular checkups and cleanings so your dentist can catch problems early.
Signs a Crown Needs Replacing
Even a good crown eventually wears out. See your dentist if you notice new pain or sensitivity, a loose or shifting crown, a dark line or gap at the gumline, or a visible chip or crack. Caught early, a failing crown is a straightforward fix.

Frequently Asked Questions
1. Do dental crowns last forever?
No, but they can last a very long time. When people ask how long do dental crowns last, the honest answer is most go five to 15 years, and some last 30 years or more with excellent care.
2. What crown material lasts the longest?
Metal crowns like gold are the most durable and longest-lasting. Zirconia is close behind and looks more natural. All-resin crowns wear out the fastest.
3. Can a crown fall off?
It can, usually because of decay under the crown or a loosened bond. If a crown comes off, keep it and call your dentist promptly.
4. Do teeth with crowns still get cavities?
Yes. The crown itself will not decay, but the natural tooth underneath and the gumline around it can, which is why daily cleaning still matters.
5. How do I know if my crown needs replacing?
Watch for pain, looseness, a dark margin at the gumline, or a chip. Your dentist can confirm whether it needs repair or replacement.
