Crowns
How Long Do Dental Crowns Last?
Dental crowns typically last 10–15 years, though many last 20 years or more with good oral hygiene and regular dental care. Material choice and habits affect longevity.
Dental crowns are a durable restorative solution, but like all dental work, they have a finite lifespan.
Average lifespan — most crowns last between 10 and 15 years. Porcelain and ceramic crowns on front teeth may last 15–20 years, while crowns on back teeth (which endure more chewing force) may need replacement sooner.
Factors affecting crown longevity:
- Oral hygiene — poor hygiene can lead to decay at the crown margin
- Material — porcelain, zirconia, and gold each have different wear characteristics
- Grinding or clenching — bruxism can crack or wear crowns prematurely
- Diet — very hard foods can damage ceramic crowns
- Regular dental visits — allowing early detection of issues
Signs a crown may need replacement:
- Visible cracks or chips
- Recurring decay at the margins
- Looseness or movement
- Pain or sensitivity
- Changes in bite
The Australian Dental Association recommends six-monthly check-ups to monitor the condition of crowns and other restorations.
When a crown does need replacement, the underlying tooth is assessed and a new crown is fabricated to fit the prepared tooth.
