### Dental Crowns: Types and Uses A dental crown is a cap shaped like a tooth that is placed over a tooth to restore its shape, size, strength, and appearance. When cemented in place, it covers the entire visible part of the tooth above the gum line. Crowns are used in various situations, such as protecting a weak tooth, restoring a broken tooth, covering a tooth with a large filling, or holding a dental bridge in place. #### Types of Dental Crowns 1. **Stainless Steel**: Often used for children's primary teeth. 2. **All Metal**: Made from gold or other alloys, known for durability. 3. **Porcelain-Fused-to-Metal**: Offers a natural tooth color. 4. **All Resin**: Less expensive but wears down faster. 5. **All Ceramic**: Best for matching natural tooth color and suitable for people with metal allergies. #### Procedure **First Visit**: The dentist examines and prepares the tooth, which may involve taking X-rays and performing a root canal if necessary. The tooth is reshaped, and an impression is made to create the crown. A temporary crown is placed to protect the tooth. **Second Visit**: The temporary crown is removed, and the permanent crown is fitted and cemented in place. #### Care and Longevity Dental crowns can last between 5 to 15 years, depending on wear and tear, oral hygiene, and personal habits. Good oral hygiene practices, such as brushing twice a day, flossing daily, and using antibacterial mouthwash, are essential. #### Costs The cost of crowns varies based on location and type, generally ranging from $800 to $1700 or more per crown. Insurance may cover part of the cost.
