What is a Porcelain Fused to Metal Crown?

Porcelain fused to metal crowns (PFM crowns) is metal crowns with a layer of porcelain fused on the metal. This makes them almost as durable as pure metal crowns but a lot more esthetic.

PFM crowns used to be the most popular crowns in dentistry for a long time. They are still used today, but nowadays ceramic crowns are preferred, especially for front teeth restorations.

PFM crowns are more affordable than all-ceramic crowns. Even though they are not as esthetic as porcelain crowns they are still good candidates for back teeth restorations.

Porcelain Fused to Metal Crown Advantages

• The outer porcelain shell is extremely aesthetic. Not only does porcelain have the same color as natural teeth, but it has very similar translucent properties. This means that teeth restored with a dental crown will look much more natural with porcelain than with other materials. 
• Both porcelain and metal are extremely durable dental materials that can withstand the pressure of chewing for long periods. If well-taken care of, they can last many years. 

Porcelain Fused to Metal Crown Disadvantages

• The combination of porcelain and metal means the crown is thicker and more of the natural tooth structure will need to be removed to allow the dental crown to fit properly. 
• As their name suggests, porcelain fused to metal crowns contains metal. This can be less than ideal for those with metal allergies or sensitivities. Additionally, the metal ring at the bottom of the crown can show through the gums or after a gum recession has occurred.
