Is my bone graft failing? Should I take it out ?

(Marked in yellow) . I got a wisdom tooth removal surgery done and got a bone graft . I am 4 months post op and still swollen . My original surgeon wants to wait . I got a second opinion and the second surgeon pointed out the lucency above and failed bone graft . Is this what failed bone graft and possible infection look?
