PERIODONTICS 
Periodontal (gum) diseases, including gingivitis and periodontitis, are serious infections that, left untreated, can lead to tooth loss. The word periodontal literally means "around the tooth." Periodontal disease is a chronic bacterial infection that affects the gums and bone supporting the teeth. Periodontal disease can affect one tooth or many teeth. It begins when bacteria in plaque (the sticky, colorless film that constantly forms on your teeth) causes the gums to become inflamed.
Not only is it the number one reason for tooth loss, research suggests that there may be a link between periodontal disease and other diseases such as stroke, bacterial pneumonia, diabetes, cardiovascular disease, and increased risk during pregnancy. Researchers are determining if inflammation and bacteria associated with periodontal disease affects the systemic diseases and conditions. Smoking also increases the risk of periodontal disease.
Four out of five people have periodontal disease and don't know it! Most people are not aware of it because the disease is usually painless in the early stages. Treatment methods depend upon the type of disease and how far the condition has progressed.
Good oral hygiene at home is essential to help keep periodontal disease from becoming more serious or recurring. You don't have to lose teeth to periodontal disease. Brush, clean between your teeth, eat a balanced diet, and schedule regular dental visits every three to six months for a lifetime of healthy smiles. That is one reason why regular dental checkups and periodontal examinations are very important.
