A dental crown is a fixed prosthetic object that is placed over a tooth or an implant, in order to restore its strength, shape or size, and to improve its esthetic  appearance or function.

Dental crowns can be crafted to repair a single tooth, multiple teeth, or even to fill a space (in conjunction with dental bridges and implants), while they can be made from various materials, such as gold alloys, porcelain, resins,  ceramics, zirconia, etc.

Although porcelain crowns are most preferable (as they are affordable and they look like normal teeth), zirconium crowns are considered to be the best choice. Zirconium  crowns are made up of zirconia (zirconium oxide) and they offer significant advantages over the other types of crowns; they can be colored and shaped to closely match any natural teeth, they are biocompatible, they have got appreciable strength, and they are corrosion resistant.

A dental crown may be needed in the following cases:

• To protect a weak tooth.
• To restore a broken tooth.
• To cover a damaged tooth or severe enamel erosion.
• To hold a dental bridge in place.
• To cover a dental implant.
• To improve a tooth’s aesthetic appearance.
