What cause periodontal disease?
Bacteria are the primary cause of periodontal infection. Bacteria form in plaque, which is a sticky, almost invisible film that forms over the teeth and destroys bone. Plaque that is not removed by regular brushing and flossing hardens into tartar over time. You cannot remove tartar (or calculus) on your own. The only way to remove tartar is by a procedure called scaling, which is done by a dentist.
