IMO, definitely try to save the tooth if you are given the option. Ask for a second opinion if you are in any doubt about it - once that tooth is gone, it's gone.

Plus - as I'm currently finding out myself - replacing a tooth with a bridge or an implant is an expensive process AND both types of replacements can develop problems of their own.

BTW don't be mad at yourself - my problem developed without dental intervention so either way it could've turned nasty, kwim?
