Dental crowns are custom-fitted tooth prosthetics that are used to cover or "cap" a damaged tooth. They are used for restoring a tooth's shape, size, strength, and to improve its overall appearance. Dental crowns encase the entire visible portion of a tooth that lies at and above the gum line.
Purposes of Dental Crowns
Dental crowns serve various purposes, from functional restoration to cosmetic enhancement. They are a versatile solution for a range of dental issues.
Restoring Structure
When a tooth is fractured, has a large filling, or is severely damaged by decay, a crown can be applied to protect and preserve the remaining tooth structure.
Enhancing Appearance
For teeth that are discoloured or poorly shaped, crowns can cover and correct the aesthetic appearance, resulting in a more pleasing smile.
Completing Dental Implants
Dental crowns are often used to complete a dental implant procedure, serving as the final step to provide a functional and aesthetically pleasing replacement for a missing tooth.
Types of Dental Crowns
Dental crowns are made from various materials, each offering specific benefits. The choice of material depends on factors such as the tooth's location, the patient's gum tissue position, the amount of natural tooth remaining, and personal preference.
Ceramic or Porcelain Crowns
Ceramic or porcelain crowns provide the best natural colour match and are more suitable for people with metal allergies. They are usually the preferred choice for front teeth.
Metal Crowns
Metal crowns are extremely durable and withstand biting and chewing forces well. They rarely chip or break and have a long lifespan. Metals used in crowns include gold alloy, other alloys (palladium), or a base-metal alloy (nickel or chromium).
Porcelain-Fused-to-Metal Crowns
These crowns provide a stronger bond than regular porcelain because they are connected to a metal structure. They are also highly durable.
The Procedure for Getting a Dental Crown
The process of getting a dental crown usually requires two visits to the dentist. The first involves examining and preparing the tooth, while the second visit involves placement of the permanent crown.
First Visit: Examination and Tooth Preparation
During the first visit, the dentist may take X-rays to check the roots of the tooth and surrounding bone. If the tooth has extensive decay or if there is a risk of infection, a root canal treatment may be performed. The tooth is then reshaped to make room for the crown.
Second Visit: Placing the Permanent Crown
During the second visit, the permanent crown is placed on your tooth. When you and your dentist are satisfied with how the crown looks and feels, it is cemented into place.
Dental crowns are a reliable solution for restoring and enhancing the function and appearance of damaged teeth. By covering the entire visible aspect of a tooth, a crown serves to strengthen, protect, and improve the cosmetic appearance of your teeth, contributing to a healthier, more vibrant smile.
