Dental crowns are prosthetic restorations that fully cup the tooth structure present above the gum line. They are permanently bonded to natural teeth to treat chips, cracks, fractures, and discoloration. Crowns are also known to strengthen and stabilize the teeth they are bonded to.
Primarily, there are four types of crowns as listed below.
All-metal crowns are fabricated from alloys of either gold or silver. They possess great strength and are highly durable, which enables them to easily withstand the chewing and biting force. They are used to restore back teeth that aren’t easily visible.
All-ceramic crowns are made from tooth-colored porcelain, which makes them look and feel like natural teeth. They are used to restore front teeth, which are known as the social six. Their tooth-colored nature enables them to easily blend in with the natural teeth.
Porcelain-fused-to-metal crowns are an amalgamation of all-metal and all-ceramic crowns. They are tooth-colored and also possess the strength and resilience of the all-metal crowns.
Performed crowns are stainless steel crowns, which are used as temporaries to fill for the permanent crowns. They are also used to cover the baby-teeth in children to protect them from decay and damage.
