A bridge is a custom device anchored to neighbouring teeth that replaces one or more missing teeth. When a lost tooth is replaced with bridgework, the teeth on either side of the missing tooth are prepared as crowns to serve as abutments to hold the prosthetic (replacement) tooth in place. Crowns and bridges are most often made from superior materials such as semiprecious or precious metals, porcelain, or a fused combination of the two. Aesthetics, function, and tissue compatibility are considered when selecting the material most suitable for you. Bridges are bonded to the teeth and are not removable. Secunderabad Dental hospital does not use semi-precious metal.
