5 to 15 years or more.
A dental crown is a tooth-shaped cap that repairs a decayed, broken, or worn-down tooth.
The lifespan of a dental crown can vary depending on several factors:
- material used
- location in the mouth
- oral hygiene practices
- individual's habits, for example, teeth grinding or chewing on hard objects
On average, dental crowns can last anywhere from 5 to 15 years or more. Here are some general guidelines for different types of dental crown materials:
- Metal Crowns: These crowns, often made of alloys like gold, are known for their durability and can last for a long time, often more than 15 years.
- Porcelain-fused-to-Metal (PFM) Crowns: These crowns combine the strength of metal with the aesthetics of porcelain. They are durable but may be more prone to chipping or cracking compared to metal crowns. Their lifespan is typically around 10 to 15 years.
- All-Ceramic or All-Porcelain Crowns: These crowns provide excellent aesthetics and are a good choice for front teeth. Their lifespan is generally around 10 years or more, but they may be more prone to chipping than metal or PFM crowns.
One of the most popular materials for ceramic crowns is zirconium dioxide. Zirconia crowns are extremely durable compared to other types of ceramic crowns.
- Temporary Crowns: These are usually placed while a permanent crown is being fabricated. They are not designed for long-term use and are typically replaced with a permanent crown within a few weeks.
If a dental crown becomes damaged or loose, it's crucial to seek prompt dental attention for evaluation and possible repair or replacement.
Regular dental examinations can help detect and address any issues with dental crowns early on, and potentially extend their lifespan.
