One option for replacing a missing tooth is a fixed partial denture, or bridge.
Bridges can be made of different materials, usually a metal alloy or a tooth-colored porcelain which is fused to a metal framework.
There are different kinds of bridges. Which bridge your dentist recommends will depend on which tooth (or teeth) are missing.
A pier abutment can support a long span bridge where teeth are missing on both sides. Often these have a stress-breaking hinge or "keyway" joining two segments.
A cantilever bridge can be used near the front of the mouth if carefully designed to prevent excess forces.
