A bridge is a restoration that replaces the space when one or more teeth have been lost. In preparing bridgework, the teeth on either side of the missing teeth must be trimmed for crown restoration in order to serve as abutments for holding the replacement teeth in place.
The loss of permanent teeth (whether it is due to dental decay, periodontal (gum) disease, injury, or accident) can cause many serious problems for neighboring teeth. When a missing tooth is not replaced, the remaining teeth surrounding the empty space often begin to shift, tilt or rotate out of alignment. This can accelerate periodontal disease and further breakdown of the existing bone structure. As a result, more teeth can eventually be lost.
The steps for fabricating a bridge are similar to a crown restoration. The procedure involves three to four visits and requires the use of local anesthesia.
