What does a dental crown do? A dental crown, also known as a tooth cap, is a dental restoration designed to cover the entire visible portion of a tooth. This restoration is commonly used to improve the appearance, strength, and functionality of a damaged or decayed tooth. In this article, we will explore the various functions and benefits of dental crowns, as well as the process of getting a dental crown.
Dental crowns are made from different materials, including porcelain, ceramic, gold, and metal alloys. The choice of material depends on the patient’s specific needs, the location of the tooth, and the aesthetic goals. Porcelain and ceramic crowns are popular for their natural appearance and durability, while gold and metal alloys are known for their strength and longevity.
Here are some of the primary functions of a dental crown:
1. Protect and Strengthen a Tooth: One of the primary functions of a dental crown is to protect and strengthen a tooth that has been weakened by decay, large fillings, or a root canal treatment. By covering the entire tooth, a crown helps distribute chewing forces more evenly, reducing the risk of further damage.
2. Improve Appearance: Dental crowns can improve the appearance of a tooth that is discolored, misshapen, or unevenly sized. Porcelain and ceramic crowns can be matched to the color of surrounding teeth, making them an excellent choice for cosmetic purposes.
3. Restore Functionality: When a tooth is damaged or decayed, it may become difficult to chew or speak properly. A dental crown can restore the tooth’s natural shape and function, allowing patients to eat and speak with ease.
4. Support a Bridge: Dental crowns are often used in conjunction with dental bridges to replace missing teeth. The crowns serve as anchors for the bridge, providing stability and support.
5. Cover a Dental Implant: Dental crowns can also be used to cover dental implants, which are artificial tooth roots placed in the jawbone. The crown is attached to the implant, restoring the appearance and function of a missing tooth.
Getting a dental crown typically involves the following steps:
1. Initial Consultation: During the initial consultation, the dentist will examine the tooth and discuss the patient’s needs and expectations. They may take X-rays and make impressions of the tooth.
2. Preparation: The tooth to be crowned will be prepared by removing a small amount of enamel to make room for the crown. The dentist will then take impressions of the prepared tooth and adjacent teeth.
3. Temporary Crown: A temporary crown will be placed on the prepared tooth while the permanent crown is being made. This temporary crown protects the tooth and ensures comfort until the final restoration is ready.
4. Final Restoration: Once the permanent crown is ready, the dentist will remove the temporary crown and place the new crown on the prepared tooth. The dentist will then check the fit, bite, and color of the crown, making any necessary adjustments.
5. Bonding: The final step is to bond the permanent crown to the tooth using dental cement. Once the cement has set, the dental crown is securely in place.
In conclusion, a dental crown is a versatile and effective restoration that can improve the appearance, strength, and functionality of a damaged or decayed tooth. By understanding the functions and benefits of dental crowns, patients can make informed decisions about their oral health and cosmetic needs.
