Crowns can be made of a variety of different materials and new materials are being introduced all the time. Here are some of the most popular options –
Porcelain bonded to precious or non-precious metal: this is what most crowns are made from. A precious or non-precious metal base is made and then porcelain is applied in layers over it.
Porcelain crowns: these crowns are made entirely out of porcelain and are not as strong as bonded crowns, but they can look very natural and are most often used for front teeth.
All-ceramic crowns: this modern material is metal free. It can give the strength of a bonded crown and the appearance of a porcelain crown. This makes it suitable for use in all areas of the mouth.
Glass: these crowns look very natural and are used on both front and back teeth.
Gold alloy crowns: gold is one of the oldest filling materials. Today it is used with other metals to increase its strength, which makes it a very hard-wearing restoration. These crowns are silver or gold in colour.
