Bone graft does help faster healing and fewer post op complications if primary closure of surgical wound is achieved. However, wound may still heal uneventfully without bone graft,just slower.
Will the bone graft also keep my teeth from shifting with the extra space filled in in the back? Otherwise I dont feel the grafts are necessary.
Wisdom tooth extraction is generally not associated with tooth shift.
Do these wisdom teeth cause you discomfort? If not, I'd leave well enough alone...they aren't gonna hurt you by nit having them removed!
My bone grafts were rejected and only created bigger cavitations....
