Dental crowns, also known as "caps," preserve the functionality of damaged teeth.
Permanent crowns can be made from stainless steel, all metal (such as gold or another alloy), porcelain-fused-to-metal, all resin, or all ceramic.
Stainless Steel Crowns(SSC) are prefabricated crowns normally used on primary teeth(in kids) as a temporary measure.
Metal Crowns : Metal crowns are stronger and withstand biting and chewing forces and may last the longest. Metal crowns are a good choice for the last molars.
Porcelain fused to metal dental crowns : These crowns can be a good choice for front or back teeth as well as long bridges where the metal is needed for strength. They can be color matched with the adjacent teeth.
All-resin dental crowns are less expensive than other crown types and are prone to fractures.
All-ceramic or all-porcelain dental crowns provide better natural color match than any other crown and can be used for front and back teeth, opted by those who have metal allergy.
