They are gum friendly. With proper technique, the contour and polish are far superior and can protect your gums better. Crowns Crowns become necessary when there is insufficient tooth structure to support a filling. Teeth that are severely broken down from decay or fracture can be fully restored to proper appearance and function with a crown restoration. Crowns cover the tooth completely, fitting just at the gumline and protecting the remaining tooth.
Most crowns have a tooth-colored porcelain exterior fused to a high noble metal base.
The shade is customized to match your other teeth so that in your mouth a crown will look just like a natural tooth. If you are missing one or more natural teeth then you know how much this diminishes your chewing ability. What you may not realize is that missing teeth also affect your facial structure, increasing stress on remaining teeth and often giving your cheeks a sunken appearance. So, in order to restore the proper function and appearance to your teeth, you should consider a bridge. Bridgework functions like a series of connected crowns, replacing missing teeth by bridging the gap and using the surrounding teeth as supports.
