A recent report from the U.S. Surgeon General outlined the direct connections between gum diseases and dental care and diabetes. First, the evidence clearly shows that gum disease occurs more than twice as often in people with diabetes as for non-diabetics, and that it is much harder for diabetics to control.
Second, diabetes can aggravate, worsen and accelerate gum disease -- which in turn, makes it more difficult to control blood sugar levels. Gum disease includes infections, which can increase your body's resistance to insulin and make your diabetes increasingly difficult to control. An enemy of blood sugar control is gum disease. An enemy of healthy gums and teeth is uncontrolled blood sugar levels: "The Closed Loop".
