Your periodontist may recommend a bone graft procedure when the bone supporting your teeth has been destroyed due to periodontal disease. These procedures can reverse some of the damage by regenerating lost bone and tissue. During this procedure, your periodontist folds back the gum tissue and removes the disease-causing bacteria. Membranes (filters), bone grafts or tissue-stimulating proteins can be used to encourage your body's natural ability to regenerate bone and tissue. Eliminating existing bacteria and regenerating bone and tissue helps to reduce pocket depth and repair damage caused by the progression of periodontal disease. With a combination of daily oral hygiene and professional maintenance care, you'll increase the chances of keeping your natural teeth – and decrease the chances of other health problems associated with periodontal disease.
