Metal crowns are commonly used to cap teeth at the back of the mouth where the reconstruction will not be visible. Metal dental crowns are strong replicas and replace or cap teeth that need to have chewing functionality. This type of dental crown is extremely durable and is likely to last for a long time without being damaged.
The main advantage of a gold crown is that the strength of the crown is similar to that of tooth enamel. This means that gold crowns will not put additional pressure on adjacent teeth when biting or chewing. As with metal dental crowns, gold crowns are used to replace molar teeth that are not visible when patients smile.

Dental crowns made from all-ceramic material provide patients the most natural looking aesthetic result. All-ceramic crowns can be made from porcelain, dental ceramic or dental resin and can be matched to blend in with the colour of natural teeth.

Ceramic crowns were not as durable as metal or gold crowns and so were not recommended for use on back molars when introduced, but evolving state-of-the-art materials and methodologies have made them an ideal replacement of natural teeth.

Porcelain fused to metal crowns are the most commonly applied dental crowns. Dental technicians construct this type of crown by making an inner shell of metal. This inner crown is then covered with a porcelain veneer to create an opaque finish that matches natural teeth. Porcelain dental crowns are recommended by dentists for front and back teeth as the metal gives the crown strength and durability while the porcelain covering disguises the crown once placed over the natural tooth.
