Your dentist mentioned a PFM crown — porcelain fused to metal. It's been the standard crown type for decades and is still widely used. Here's how it compares to newer all-ceramic options.
What Is a PFM Crown?A PFM crown has a metal base that provides strength, covered by a layer of tooth-coloured porcelain. The metal gives the crown its structural integrity while the porcelain gives it a natural appearance.
This combination has made PFM crowns the workhorse of restorative dentistry for over 50 years. Dentists have extensive experience with them and they have a strong track record.
Advantages of PFM CrownsPFM crowns are extremely durable. The metal core resists fracture and can withstand heavy biting forces, making them suitable for back teeth. They're also generally less expensive than all-ceramic alternatives.
These crowns have been extensively studied and have excellent long-term survival rates. Your dentist knows exactly how they perform over many years of use.
Potential DrawbacksOver time, the gum margin can recede, exposing the dark metal edge of the crown. This can create an unsightly grey line at the gum, particularly noticeable on front teeth.
The porcelain layer can chip or fracture, though this is relatively uncommon. Some patients also experience sensitivity to hot and cold with PFM crowns due to the metal conducting temperature.
How Do They Compare to All-Ceramic Crowns?Modern all-ceramic crowns like zirconia and E-Max offer superior aesthetics with no metal showing. They transmit light naturally, mimicking real tooth structure more closely.
All-ceramic options are also more biocompatible and less likely to cause gum discolouration. However, PFM crowns can still be the best choice for certain situations, especially in the back of the mouth where strength is paramount.
When Might Your Dentist Recommend PFM?PFM crowns are often suggested for back teeth where maximum strength is needed. They're also a solid choice if cost is a significant factor in your treatment decision.
Your dentist will consider the location of the tooth, your bite forces, cosmetic needs, and budget when recommending the most appropriate crown type for you.
