Loose Bridge

I have a bridge on teeth #10, #11, #12 & #13 since #11 & #12 are missing teeth.
Now the bridge is loose on #10 but still attaching firmly on #13. Is there any way to remove the bridge without breaking it and re-adhesive it to the original place (my dentist says I can’t leave it as bacteria will go inside and damage my teeth, he tried to remove it but failed)?
If finally, the bridge has to be break in order to remove, should I install a new bridge or implant #11 & #12 and put crowns on #10 & #13. Here is some more information; I got root canal treatment, re-treatment and apical surgery on #10.
I appreciate very much for any advice.

There's a possibility to try to knock the bridge loose with a crown tapper but you run the risk of breaking the teeth underneath.  I would recommend having the dentist section (cut) the bridge off the teeth and replace the missing teeth with implants, knowing that #10 may possibly be extracted in the future if symptoms present themselves.
