How long do porcelain-fused-to-metal (PFM) crowns typically last?

The typical lifespan of a porcelain-fused-to-metal (PFM) crown is approximately 10 years. Generally, PFM crowns are durable and do not experience severe wear or loosening, allowing them to remain functional for extended periods. However, if chipping (porcelain fracture) or significant wear occurs, replacement should be considered. Patients are advised to maintain good oral hygiene and healthy lifestyle habits in daily life, and to follow a mild, non-irritating diet.
