The average dental crown lifespan is about 10 to 15 years, though many crowns last 20 to 30 years or more with good care. Dental crown durability depends on the material, your bite, and your oral hygiene. Regular checkups help your crown last as long as possible.
A crown is an investment in your tooth, so it makes sense to ask how long it will last. The reassuring answer is: usually a long time. Here is what affects dental crown durability, and how to get the most from yours. For materials, see our types of dental crowns guide.
How Long Do Dental Crowns Last?
Most crowns last about 10 to 15 years, and many go well beyond that, often 20 to 30 years or more, with good care. The exact dental crown lifespan depends mostly on the material and how well you look after it.
Lifespan by Crown Material
| Material | Typical Lifespan |
| Gold or metal alloy | 20 to 30+ years |
| Zirconia | 15 to 25+ years |
| Porcelain fused to metal | 10 to 15+ years |
| All-porcelain or ceramic | 10 to 15 years |
Expert Insight
Most crowns do not fail because the crown itself wears out. They fail because decay forms where the crown meets the tooth, at the margin. That is why daily brushing and flossing around the crown, and regular checkups, matter just as much as the material.
What Affects Dental Crown Durability
- Material: Metal and zirconia are the toughest; all-ceramic slightly less so.
- Oral Hygiene: Decay at the crown’s edge is the most common reason crowns fail.
- Grinding and Clenching: These wear crowns faster. A night guard helps.
- Habits: Chewing ice or hard objects can chip or crack a crown.
- The Bite: A well-fitted crown that meets your bite correctly lasts longer.
How to Make Your Crown Last Longer
- Brush twice a day and floss once a day, especially around the crown.
- Wear a night guard if you grind your teeth.
- Avoid chewing ice, pens, or very hard foods.
- Keep your regular dental checkups and cleanings.

FAQs About Dental Crown Lifespan
Q1. How Long Do Dental Crowns Last?
Most dental crowns last about 10 to 15 years, and many last 20 to 30 years or more with good care. The lifespan depends on the material, your bite, and your oral hygiene. Regular checkups and daily care around the crown help it last as long as possible.
Q2. Which Crown Material Lasts the Longest?
Gold and metal crowns last the longest, often 20 to 30 years or more, followed by zirconia. All-porcelain and PFM crowns typically last 10 to 15 years. Whatever the material, good hygiene and regular checkups make a real difference to lifespan.
Q3. Why Do Dental Crowns Fail?
Crowns most often fail because decay forms where the crown meets the tooth, not because the crown wears out. Grinding, chewing hard objects, poor hygiene, and an ill-fitting bite also shorten lifespan. Daily care around the crown and regular checkups prevent most failures.
Q4. Do Crowns Need to Be Replaced?
Many crowns eventually need replacing once they loosen, chip, or develop decay at the edge, often after 10 to 20 years. Some last a lifetime. Your dentist checks your crowns at each visit and recommends replacement only when it is genuinely needed.
Q5. How Can I Make My Crown Last Longer?
Brush twice a day and floss around the crown daily, wear a night guard if you grind, avoid chewing ice or hard objects, and keep your regular checkups and cleanings. These simple habits protect the tooth underneath and extend your crown’s life.
Q6. Can a Crown Last a Lifetime?
Some crowns do last a lifetime, especially gold or zirconia with excellent care. Most, though, are replaced at some point as the tooth and the crown’s edge change over the years. Good hygiene and regular visits give you the best chance of a very long-lasting crown.
