Another approach -- make sure you have a relaxed rest position.
I have had extensive dental work over the years, with enough root canals, crowns, fixed bridges, and now a few implants to qualify for infrastructure week. After a certain point, especially with multi-tooth bridges, it became very difficult to get the ideal all-around tooth contact I'd had before. I found that I was causing myself a lot of pain by constantly testing my bite, esp. near the site of the most recent repair.
Eventually I heard about making a conscious effort to maintain a relaxed rest position -- teeth aren't in contact except when chewing. It took a few weeks to learn to relax my jaw all day long (and resist the impulse to tap tap tap), but it made a big difference in comfort for me.
Good luck,
