Tooth Crown

A Tooth Crown is a type of dental restoration which completely caps or encircles a tooth or dental implant. Tooth crowns are often needed when a large cavity threatens the ongoing health of a tooth. They are typically bonded to the tooth by dental cement. Crowns can be made from many materials, which are usually fabricated using indirect methods. Crowns are often used to improve the strength or appearance of teeth.

Types of Tooth Crown

There are four types of dental crowns:

1. Metal Crowns: These are made from gold, platinum, or base metal alloys. They are durable and can withstand biting and chewing forces.
2. Porcelain-fused-to-metal Crowns: These can be color-matched to your adjacent teeth. They have a more natural tooth color.
3. All-resin Crowns: These are less expensive than other crown types. However, they wear down over time and are more prone to fractures.
4. All-ceramic or all-porcelain Crowns: These provide the best natural color match than any other crown type. They are also a good choice for people with metal allergies.

Procedure

The procedure for installing a tooth crown typically involves two visits to the dentist. The first step involves examining and preparing the tooth, the second visit involves placement of the permanent crown.

Risks

While generally safe, as with any procedure there are risks and potential complications. These may include tooth decay, gum disease, and crown displacement.

Maintenance

With proper care, a good quality crown could last up to 15 years. It is important to maintain good oral hygiene and avoid habits such as grinding or clenching teeth, chewing ice, biting fingernails, and using teeth to open packaging.
