When periodontal disease has destroyed the bone supporting your teeth this damage can be reversed by regenerating lost bone and tissue. Naturally it is first essential to remove the disease-causing bacteria. Membranes, bone grafts or tissue- stimulating proteins can be used to encourage your body's natural ability to regenerate bone and tissue. The best way to prevent cavities and periodontal diseases is when good tooth brushing and flossing techniques are performed daily. Periodontal disease and decay are both caused by bacterial plaque. Plaque is a colorless film, which sticks to your teeth at the gum line. Plaque consists of germs on your teeth. By thorough daily brushing and flossing you can remove these germs and help prevent disease and you can avoid spending much for periodontal surgery.
