The case is different though with advanced periodontal disease wherein the gum can’t fit snugly with the tooth or there’s significant loss of bone structure surrounding the affected tooth.   Gum and bone grafts might be required to repair the loss. In some cases the pocket may just be reduced to make the gum fit snugly with the tooth. The treatment might be different from patient to patient depending on the severity of the damage.   It’s especially the case when bone grafts are required. Periodontal disease can destroy bone structure in a particular area. The loss can be solved by placing natural or synthetic bone, and then stimulating the area to regrow bone and tissue.
