I am not exactly sure what you mean by saying the jaw never healed, is it still an open wound ? In my case, I think the wound has been healed but I had and still have infection around the site where the jaw bone was cut. A metal plate was placed during the surgery to connect the jaw bone. The doctor is suspecting that I do not tolerate this metal plate so is considering to remove it. Although there are some risk involed but I think I will do that anyway. Because this repeated infections are terrible.
