Most dental bridges and all crowns are fixed prosthetic devices that are cemented onto one’s existing teeth or implants. However, there are differences between crowns and bridges.
A dental crown is a tooth-shaped cap or cover that goes over one’s damaged tooth to offer reinforcement, which allows the natural tooth to last longer. The crown fits identically to a natural tooth, because it is created from exact impressions that the dentist makes.
In addition to strengthening and reinforcing a damaged tooth, dental crowns can be used to improve the shape, appearance or alignment of a tooth. Crowns are also used with implants, to provide teeth with more natural shapes and better structure for function.
Different materials are used to create dental crowns. Ceramic or porcelain is often used for this purpose, because the dentist is able to more closely match the color of one’s natural teeth with these materials. However, ceramic, metal alloys, acrylic and gold can also be used. However, these alloys are more often used for the back teeth. Another alternative is the use of porcelain that is bonded to a metal tooth shell. This provides a tooth that is both attractive and fortified.
After tooth loss, the remaining teeth can shift out of place and increase the chances of contracting gum diseases and TMJ disorders. Dental bridges differ from dental crowns, in that they are used to literally bridge the gap between teeth that are missing. In other words, they are used to replace one of more missing teeth by spanning the space left by the missing teeth when cemented to the implants or teeth that surround the empty space.
