A dental crown is a tooth-shaped "cap" that is placed over a tooth – covering the tooth to restore its shape and size, strength, and/or to improve its appearance. The crowns, when cemented into place, fully encase the entire visible portion of a tooth that lies at and above the gum line.
A dental crown may be needed in the following situations:
To protect a weak tooth (for instance, from decay) from breaking or to hold together parts of a cracked tooth
To restore an already broken tooth or a tooth that has been severely worn down
To cover and support a tooth with a large filling when there isn't a lot of tooth left
To hold a dental bridge in place
To cover misshaped or severely discolored teeth
To cover a dental implant
There are basically three types of crowns, those made of gold, ceramic crowns and ceramic-veneered gold crowns. Gold and metal-ceramic crowns are extremely durable and are normally used in molars, where the forces from chewing and grinding are most prevalent. Ceramic crowns are used primarily for front teeth, since they can best resemble the natural tooth color.
Resin and Porcelain Crowns
The new reinforced resin or bonded all-porcelain type of crown has the nicest appearance. This crown can be made from pure ceramic or a new reinforced composite resin, and is almost indistinguishable from natural teeth. The new bonding technology provides an exceptional bond to your tooth. It is metal-free, and thus satisfies the needs of patients with metal sensitivities. When correcting your back teeth with bonding, the cosmetic dentist will perform a tooth colored onlay. This type of procedure is used to correct only those parts of the tooth that are in need. This is a metal-free procedure.
Crowns Made of Gold
Gold crowns are appropriate when appearance is not a priority to you. The gold metal is extremely workable making gold crowns a more precise fit than any other type. While there exists a slight possibility of chipping with porcelain crowns, gold crowns provide no such possibility.
Porcelain and Metal Crowns
For a very natural appearance, porcelain fused to metal crowns are the answer. However, they have a metal substructure and require an opaque below the porcelain. This can make the translucency of natural teeth difficult to replicate. Occasionally a darker line will be visible at the edge of the crown, near to your gum when it recedes with age.
Types of Porcelain
There are basically two types of porcelain you are likely to hear and read about most - the felspathic and pressed ceramic porcelains. The felspathic type is the original method that has been around for 20 years. A Ceramist in a dental lab bakes porcelain onto tin foil and then heats it in an oven. The Ceramist is able to create tints and opaques inside the porcelain to give the natural look we seek.
Pressed ceramic is created from a single ingot. The single ingot is milled in one piece to create the desired shape. The stains and opaques are applied only to the surface of the porcelain to give a natural look.
