This is a tooth replacement option for filling the space created by a missing tooth or two adjacent missing teeth. Basically a bridge consists of multiple crowns welded together and cemented to the teeth on both sides of the missing tooth/teeth.
A bridge replaces the missing tooth, both functionally and cosmetically. Bridgework is as much an art as it is an exact science. The materials used may be gold alloys, porcelain bonded to a metal alloy, or an all ceramic material. The choice of material depends on requirements for strength, wear, and/or esthetics.
It is important that a missing tooth be replaced as soon as possible for several reasons. If not treated in a timely manner, the teeth surrounding the space begin to shift inward, creating a whole chain reaction of bad things. Teeth use their neighbors for support, and with one missing, they start to tip or “fall” into the space of the missing tooth. As this worsens, the bite changes in response to the pressure. This can eventually result in problems with the entire jaw, e.g. TMJ. As the surrounding teeth continue to tip, oral hygiene becomes more difficult and the likelihood of decay and gum disease increase. With time, treatment becomes more difficult and eventually the teeth may be lost.
