Metal crowns may be made of materials including alloys of gold or other non-precious metal-based alloys. These types of crowns require the least amount of tooth substance to be removed because the metal base is in a thin section. Metal-based crowns are very good at taking biting forces and are very good crowns to be placed in the back molar regions where aesthetics are not so important but chewing strength is.

Porcelain fused to metal crowns are a very good choice for both anterior and posterior teeth. They can be colour matched to one’s own existing teeth.

Metal free all ceramic crowns represent the ultimate in high aesthetics and superb looks. They are a very good choice for front teeth, although they are not as strong as porcelain fused to metal crowns.
