Periodontal disease [Periodontitis] is a serious gum infection that damages the gums, jawbone and can lead to tooth loss. Having periodontal disease will heighten your risk for heart and lung diseases as well.
Periodontal disease is common but is fairly easy to prevent. It is usually caused due to poor oral hygiene. The symptoms include swollen, red and tender gums. Often times, you might hear 'Gingivitis' which is the first stage of periodontal disease.
Treatment for this includes deep cleanings which clean the pockets around the teeth to prevent damage surrounding the bone. In addition some people need more frequent cleanings to help prevent the start of periodontal disease and may need to be every 3 months.
