Dental crowns are strong constructs that are made to replace the part of the tooth that sits above the gumline. Typically, they’re made of porcelain bonded to metal, but they can also be made of plain porcelain, special types of glass, gold, and other materials. Crowns are made to exact shape of the tooth and then fitted onto the tooth. They cover every part of the tooth down to the gums. Crowns will strengthens the damaged tooth, and are aesthetically pleasing.
Crowns are needed whenever the tooth’s natural crown has become too damaged to support normal chewing function or to protect the interior of the tooth. They are required after root canal therapy to close the hole that was made for the procedure. They’re also needed to restore teeth after extensive decay has been removed. Crowns can fix broken or cracked teeth as well.
