PFM Crown (Porcelain Fused to Metal)

A type of dental crown that has a cast metal substructure (for strength) covered by layers of tooth-colored porcelain (for aesthetics).

Why It Matters

For decades, this was the gold standard. It is strong enough for back molars. However, over time, a "dark line" (the metal edge) often appears at the gumline, which is why many patients now prefer Zirconia (metal-free) crowns.

Clinical Details

• Durability: 10-20 years.
• Risk: The porcelain can chip off the metal if the patient grinds their teeth.
