Porcelain fused to metal crowns (or PFM crowns) can be referred to as full-cast crowns which has porcelain fused on most or all parts of the tooth. Metal alloys with a high melting temperature are used to fuse porcelain to the surface and preventing the metal from melting. This ensures the porcelain to bond without changing its color.
When the tooth is prepared for such crowns, a large part of the tooth tissue gets removed making space for porcelain as well as the metal.
In receding gums, such crowns are not suitable as the porcelain can start showing distinctively. They are best suited for the back and front teeth.

How much does a PFM crown cost?
As always, there can be huge differences in prices depending on your location, size of the crown and the experience of the dentists. However, in case of porcelain fused to metal crowns and additional reason for the price difference is the metal in the crown. This metal could be a high noble metal (usually gold), but it could also be a cheaper one, like silver, cobalt-chrome or nickel. Your best bet is to buy a crown that is fused to gold. This is considered to be the highest quality, even though this is the most expensive option. It's also good to know that nickel might cause allergic reaction in some people.
When comparing quotes from multiple clinics, it's best to ask what metal they use. It's easy to beat the price of a porcelan fused to gold crown with a porcelain fused to nickel one. You might also want to ask if the clinic uses a local dental lab or imports the crowns - e.g. from China.
