For large tooth restorations such as crowns, metals are often used. They are very strong and resist cracking and wear. They can also be highly resistant to corrosion and tarnishing. Since metal alloys have a dark color, they do not look like natural teeth.
Gold alloys contain gold, copper and other metals. Less of the natural tooth may need to be removed than with some other restorations. They may cost more than other restorative options. Base metal alloys look like silver. They are used in crowns, fixed bridges and partial dentures.

Dr. Philip Uffer answered:When there is limited space for the restoration, metal is a good choice. A thickness of 0.7mm still has respectable strength in many instances. 1mm is ideal for most applications. Some materials require more thickness to have strength.When there is limited space for the restoration, metal is a good choice.
