A crown on a tooth, also known as a dental crown or dental cap, is a custom- made, tooth-shaped "cap" that completely covers or encircles a damaged, decayed, or weakened tooth above the gum line. It is permanently cemented onto the prepared natural tooth to restore its size, shape, strength, and appearance

. Purpose and Uses of a Dental Crown:

• Protects and strengthens teeth that have large cavities, cracks, fractures, or extensive fillings

• Shields teeth after root canal treatment to prevent brittleness and further damage

• Restores worn-down or broken teeth, allowing normal biting, chewing, and speaking

• Improves aesthetics by covering discolored, misshapen, or poorly aligned teeth, matching the natural tooth color and shape

• Supports dental implants by acting as the visible tooth replacement on top of the implant

Materials and Fabrication:
Crowns can be made from various materials such as porcelain, metal (including gold), or a combination. They are typically fabricated outside the mouth using impressions or computer-aided design and manufacturing (CAD/CAM) technology, allowing the use of strong and durable materials

. Benefits:

• Provides a durable protective layer that prevents further deterioration and damage to the tooth

• Restores full tooth function and appearance, enabling comfortable biting and chewing

• Enhances smile aesthetics and boosts confidence

• Versatile treatment option for a wide range of dental issues

In summary, a dental crown is a restorative dental prosthetic that covers a tooth to protect it, restore its function, and improve its appearance when the tooth is significantly compromised
