How the Crown Restores Tooth Integrity- Understanding the Mechanism of Dental Crowns
How Does a Crown Work on a Tooth?
Tooth crowns are dental restorations that are designed to cover the entire visible portion of a tooth, restoring its shape, size, and function. They are commonly used to protect weakened or damaged teeth, improve their appearance, and restore their ability to chew and bite. But how exactly does a crown work on a tooth? Let’s delve into the details.
Material and Structure
Crown materials include porcelain, ceramic, gold, porcelain-fused-to-metal, and resin. Each material has its own set of advantages and disadvantages, and the choice of material depends on various factors such as the tooth’s location, the patient’s preferences, and the dentist’s expertise. Once the material is selected, the tooth is prepared by removing a small amount of its structure to accommodate the crown’s thickness.
Preparation and Fitting
The tooth preparation process involves shaping the tooth to allow the crown to fit snugly over it. The dentist will take an impression of the prepared tooth and its adjacent teeth to ensure that the crown fits properly and is in harmony with the bite. The impression is then sent to a dental laboratory, where a skilled technician will create a custom-fitted crown.
Application
Once the custom-fitted crown is ready, the dentist will cement it onto the prepared tooth. The application process typically involves the following steps:
1. Cleaning the tooth surface to ensure a strong bond between the tooth and the crown.
2. Applying a bonding agent to the tooth.
3. Placing the crown onto the tooth and adjusting its position for a proper fit.
4. Securing the crown with dental cement.
Functionality and Longevity
A properly placed crown can last for many years, often lasting between 5 to 15 years or even longer. The crown works by providing a strong, protective layer over the tooth, preventing further damage and decay. It also helps in maintaining the tooth’s shape, size, and function, allowing the patient to chew and bite with ease.
In conclusion, a tooth crown works by covering the entire visible portion of a tooth, providing protection, improving appearance, and restoring functionality. The process involves tooth preparation, custom crown creation, and application, all of which are carried out by a skilled dentist. With proper care and maintenance, a tooth crown can significantly enhance the health and longevity of a damaged tooth.
