is it possible/wise to extract a tooth which is part of a bridge?

i have a bridge that is failing. it is the last remaining 1/3 of an original bridge which was an upper "roundhouse" constructed in three parts, soldered together. the other 2/3s of the bridge are gone.

last week a piece of the porcelain attached to the left front incisor disintegrated, leaving an opening 1/32" wide by 1/16" long. it is quite painful now, but had caused no pain at all prior to the disintegration.

i saw a prosthodontist who suggested re-doing the bridge but recommended first that i see an endodontist for a root canal on the fractured tooth before he could create a new bridge.

because of all the unfavorable reviews i've read of root canal therapy, i am very leery of it & would prefer to have the incisor extracted.

i would like to suggest the idea of extracting the tooth but want some idea of its feasibility before i see him again.

i would appreciate any thoughts & suggestions!
