Wearing The Crown

A crown sounds so much fancier than a cap, doesn't it?

Dental crowns, formerly known as caps, are a form of dental restoration that completely caps the tooth or implant. They are bonded to the tooth using a resin and are often used to improve the strength of a broken tooth.

Typically you will have an impression made in the dentist's office and the crown will be fabricated in a lab. The taking of the impression is the yucky part. That plastic tasting stuff is gross. You will have a temporary metal crown to protect the tooth until the final crown arrives.

Several types of materials can be used to craft the crown. Full gold crowns are made from a single piece of alloy. They are not entirely made of gold. They can contain gold, platinum, or silver known as noble metals. Base metals such as copper and tin are also used. To be a full gold crown they must contain 60% noble metals, 40% of which must be gold.

Another type of crown is

porcelain fused to metal. The thin porcelain is placed over a strong metal base to give a natural appearance. These are suitable for use on front teeth. The latest thing in making crowns is called CAD/CAM. No impressions are needed because a 3-D image of the prepared tooth and surrounding areas is captured and stored. Then using computer technology, the dentist can make changes and send directions to a local milling machine. This machine will create a solid ceramic crown which can then be used immediately.

The crown will last about ten years. The main disadvantage to using a crown for restoration is the irreversible destruction of the tooth underneath. Crowns are also used on the teeth on either side of a fixed bridge used to replace a missing tooth. With the advent of dental implants, using a crown on adjacent teeth is not necessary. Crowns fashioned using the CAD/CAM method do not require the underlying tooth to be ground down as much.

Gone are the days when a "capped" tooth was obvious. The new methods of restoration dentistry make the teeth look beautiful and as if you were born with them.
