Dental Crowns

Crowns can restore both the strength and beauty to your natural teeth

About Dental Crowns

Dental crowns or “caps” offer a solution for teeth that are too badly damaged to be corrected with tooth-colored fillings or veneers. Crowns can restore both the strength and beauty to natural teeth. There are generally three types of crowns: – those made of gold, all-ceramic caps and ceramic-veneered gold crowns. Gold and metal-ceramic crowns are extremely durable and are normally used on 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 and are more pleasing to the eye.

Dental Crowns

Types of Porcelain Used With Dental Crowns
There are basically two types of porcelain used in dental caps and crowns: feldspathic and pressed ceramic porcelains. The feldspathic type is the original method that has been around for 20 years.

Pressed ceramic is created from a single ingot. The ingot is melted and pressed in one piece to create the desired shape of the cap or crown. The stains and opaques are applied only to the surface of the porcelain to give a natural look for your new smile.

Resin and Porcelain – Crowns and Onlays
The new reinforced resin or bonded all-porcelain cap has the nicest appearance in cosmetic dentistry. This cap can be made from pure ceramic or a new reinforced composite resin. It is almost indistinguishable from natural teeth. The new bonding technology involved provides an exceptional bond 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 the parts of your tooth that are in need. This procedure is metal-free.

Dental Crowns Made of Gold
Gold crowns are used when appearance is not a priority to you. The gold 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 for you. However, they have a metal substructure and require an opaque below the porcelain, which can make the translucency of natural teeth difficult to match. Sometimes a darker line will be visible at the edge of the crown, near to your gum, when your gum recedes with age.

When are porcelain crowns fused to gold the best choice?
When the restoration of teeth require a crown in an area of high biting force, a ceramic porcelain crown strengthened with a metal, typically a gold alloy, may be called for. These restorations have been improved over the forty years since their introduction to dentistry and can rival the cosmetics of an all-ceramic crown when done properly. Porcelain fused to gold crowns looks like natural teeth and are stronger than ceramic crowns. This system can be matched to your natural teeth so they provide an attractive appearance. They are a good choice for front or back teeth.
