Is this common practice? What might cause the result?

I was told a gap under a crown of 11 years would eventually allow entry of bacteria and cause a problem [that tooth has had root canal] so it should be, essentially "caulked". The crown is on one side of a bridge. I wasn't having any problem prior but it sounded reasonable to avoid a possible more expensive future problem. In the three weeks since then I have almost constant dull pain [needing ibuprofen] from the pressure of eating [no hot/cold issue]. I took an antibiotic but still a problem. X-ray looks good and shows the gap is gone. Any thoughts on what could have gone wrong? Thanks.
