Can a crown last a lifetime?

Some crowns — particularly gold — can last 20 to 30 years or more. Most crowns will eventually need replacement, but with good oral hygiene, regular checkups, and a night guard if you grind, many patients get 15 to 20 years from a single crown.

What shortens the life of a crown?

Teeth grinding (bruxism) is the most common cause of premature crown failure. Other factors include poor oral hygiene that allows decay at the crown margin, chewing ice or hard objects, and using teeth as tools.

Does the tooth under a crown still need care?

Yes. The tooth under a crown can still develop decay at the margin where the crown meets the tooth. Brushing, flossing, and regular cleanings are essential to prevent secondary decay that can compromise the crown.

What happens if a crown falls off?

Call your dentist right away. Keep the crown if possible — it may be recemented. Do not try to reattach it yourself with household glue. The exposed tooth is vulnerable to sensitivity and damage until the crown is replaced.

Is it normal for a crown to feel sensitive?

Some sensitivity is normal for a few weeks after crown placement as the tooth adjusts. Persistent or worsening sensitivity, especially to cold or biting, should be evaluated — it may indicate the crown needs adjustment or the tooth has developed a problem.

Quick Answer

Dental crowns typically last 10 to 15 years, and many last 20 years or more with proper care. Longevity depends on the crown material, your bite forces, oral hygiene, and whether you grind your teeth. Porcelain-fused-to-metal and full-zirconia crowns are among the most durable options available today.

How Long Do Different Crown Materials Last?

Crown material is the single biggest factor in longevity. Your dentist will recommend the best material based on the tooth's location, your bite, and your aesthetic goals.

Porcelain-fused-to-metal (PFM): 10–15 years

A metal substructure with a porcelain exterior. Very durable, but the porcelain can chip over time and a dark line may appear at the gumline as gums recede.

All-ceramic / all-porcelain: 10–15 years

Excellent aesthetics and biocompatibility. Best for front teeth. More prone to chipping under heavy bite forces than metal-based crowns.

Zirconia: 15–20+ years

Zirconia is extremely strong and tooth-colored. It is now the most commonly placed crown material and is highly resistant to chipping and fracture.

Gold / metal alloy: 20–30+ years

The most durable crown material. Gold crowns rarely chip or fracture and are gentle on opposing teeth. Still preferred for back molars in patients who grind heavily.

Porcelain-fused-to-zirconia: 15–20 years

Combines the strength of zirconia with a more natural-looking porcelain exterior. A popular choice for visible back teeth.

Signs Your Crown May Need Replacing

Watch for these signs that a crown may need attention: pain or sensitivity when biting, a crack or chip you can feel, visible darkening at the gumline, the crown feeling loose or rocking, food consistently catching around the crown, or a crown that has fallen off. Your dentist evaluates crown margins at every exam and can often detect wear or leakage before you notice symptoms.
