what type of tooth crown is better
1 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. 2  Metal crowns withstand biting and chewing forces well and probably last the longest in terms of wear down. 3  Also, metal crowns rarely chip or break.
Crowns may be made from several different materials, gold and porcelain being the most common types. Gold is usually used on the back teeth, as it has several advantages over porcelain teeth. - Gold is strong in thin section and less tooth needs to be drilled away before taking the impression and fitting the crown.
