Porcelain fused to metal crowns are more affordable than all ceramic crowns. Even though they are not as aesthetic as porcelain crowns they can still be used especially as back teeth in your mouth.
The metal is used to fuse the porcelain to the surface without changing its color. At the beginning of the process a large part of the tooth surface is removed in order to make space for the metal and the porcelain. Then a metal shell is prepared to cover the tooth and a porcelain veneer is fused to the metal, which gives the crown a natural looking appearance.
