What is the difference between a crown and a cap? This is a common question that many people have when they are considering dental restoration options. Both crowns and caps are dental prosthetics designed to restore the shape, size, and strength of a damaged tooth. However, there are distinct differences between the two that can affect the choice of treatment for each individual case.
Crown and cap are often used interchangeably, but they refer to slightly different dental restorations. A crown is a dental prosthetic that covers the entire visible portion of a tooth, while a cap is a type of crown that is placed on the tooth’s chewing surface. Understanding the differences between the two can help patients make informed decisions about their dental care.
Firstly, the primary difference between a crown and a cap lies in their application. A crown is used to cover the entire tooth, providing a comprehensive restoration. This is typically done when a tooth has been significantly damaged due to decay, fracture, or other dental issues. On the other hand, a cap is specifically designed to fit over the chewing surface of the tooth, which is usually the case when a tooth has been weakened by decay or has undergone a root canal treatment.
Secondly, the materials used to make crowns and caps differ. Crowns can be made from various materials, including porcelain, metal, ceramic, or a combination of these materials. The choice of material depends on factors such as the tooth’s location, the patient’s aesthetic preferences, and the desired strength and durability. Caps, on the other hand, are usually made from porcelain or porcelain fused to metal, as these materials provide both strength and a natural appearance.
Another key difference between crowns and caps is their appearance. Crowns are designed to blend in with the surrounding teeth, making them less noticeable. This is particularly important for front teeth, where an aesthetically pleasing restoration is crucial. Caps, while also designed to look natural, may be more noticeable due to their placement on the chewing surface of the tooth.
The process of getting a crown or cap also varies. A crown typically requires two visits to the dentist. During the first visit, the dentist will prepare the tooth by removing any decay or damaged tooth structure and taking an impression of the tooth. The impression is then sent to a dental laboratory, where the custom crown is made. The patient returns for a second visit to have the crown cemented into place. In contrast, a cap is usually placed in a single visit, as it is often made on-site using a dental CAD/CAM system.
In conclusion, while both crowns and caps are dental restorations designed to restore the function and appearance of a damaged tooth, there are distinct differences between the two. Understanding these differences can help patients make informed decisions about their dental care and choose the most suitable restoration for their individual needs.
