Are you a dentist: please weigh in on your diagnosis, patient has pain in bottom tooth

Not enough detail in your request. And the radiograph is far too pixellated to assess the RCTs.
What do you mean by " pain"? Consider this sheet that I give to my assistant dentists.

1. Eating pressure?
2. Hot or cold?
3. Percussive pain?
4. Taking analgesics; if so, to what effect?
5. Pain to ear, or to temple?

Just going from what I can see, there's been a deep composite on the premolar. That'd be my first guess.

I agree with Dr. MattKW with the premolar as well as its margin gaps. Also from the image quality, it appears that restorations of the 2 posterior molars have open margin gaps or large pooling of radiolucent cement/bonding agent.
