Bacteria in the mouth infect the tissue surrounding the tooth and cause inflammation around the tooth and cause periodontal disease. When bacteria stay on your teeth long enough, they form a film called plaque, which eventually hardens and becomes tartar, also called calculus. Tartar buildup can spread below the gum line, making it difficult to clean your teeth. Then, only a dental health professional can remove tartar and stop the periodontal disease process.
Periodontal (gum) disease is an infection of the tissues that hold teeth in place. It's usually due to poor brushing and flossing habits that allow plaque, a sticky film of bacteria, to build up on your teeth and harden. In advanced stages, periodontal disease can cause pain and bleeding in the gums, painful chewing problems, and even tooth loss. CDC efforts include (developing measures for use in periodontal disease surveillance at the state and local levels), (improving the validity of prevalence estimates derived from the NHANES (National Health and Nutrition Examination Survey) by improving the accuracy of clinical examination.
The protocols used in this national survey and (the development of simple measures for the detection of periodontal disease in clinical settings).
