How long does a porcelain-fused-to-metal crown usually last?

The lifespan of porcelain-fused-to-metal (PFM) crowns is generally around 5 to 10 years, but the exact duration varies depending on several factors. 1. The type of dental crown significantly affects its longevity. For example, metal-based PFM crowns typically last between 5 to 7 years, whereas all-ceramic crowns usually last between 7 to 10 years. 2. The quality, design, and marginal seal of the crown also influence its lifespan. High-quality crowns with proper design and excellent marginal fit can effectively extend their service life. 3. The patient's daily care and oral hygiene habits are equally important. Good maintenance and cleaning routines can significantly prolong the lifespan of dental crowns. When choosing dental crowns, it is advisable to select reputable hospitals and high-quality materials, and to maintain proper daily care to maximize their longevity.
