Dental Benefit, Metal Crowns
Metal Crowns: Metal used in crowns include gold alloy, other alloys or a base-metal alloy such as nickel or chromium. Compared with other crown types, less tooth structure needs to be removed with metal crowns, and tooth wear to opposing teeth is kept to a minimum. Metal crowns withstand biting and chewing forces well and probably last the longest in terms of wear down. Also, metal crowns rarely chip or break. The metallic color is the main drawback. Metal crowns may be a good choice for out-of-sight molars.
