I am facing problem of food lodging and gum pain between capped and adjacent teeth. Any suggestions? (photos)

There are two possible problems here. The first could be that the contact between the two teeth isn't tight enough when the crowns are being inserted. The contact area between the two needs to be broad enough to prevent food from getting stuck. The second possible problem is that the second molar is shifting and causing a space to open. Your dentist needs to evaluate this situation because you will get decay in the area if food continues to sit there.

It may be that the new crown does not have a tight enough fit or broad enough contact. Since this is the second one placed,though, it may be more likely that your bite or occlusal contacts need to be adjusted. An upper molar may have a plunging cusp that is hitting right in between the two lower molars causing the space to reopen. The dentist can evaluate this and also check the mobility or looseness of the teeth if there is bone loss around them which is enabling the back molar to move more easily.
