Diabetes is a group of chronic inflammatory diseases that affect the body's ability to process sugar. If you have diabetes, it is particularly important to maintain excellent oral health. That's because diabetics are more prone to oral infections such as periodontal (gum) disease, which can result in tooth loss if left untreated. Conversely, the presence of gum disease can make it harder for people with diabetes to control their blood sugar levels.
Periodontal disease is a chronic ailment that is also associated with an elevated level of systemic (whole-body) inflammation. Like diabetes, it may have wide-ranging consequences outside the mouth — possibly increasing a person's chance of experiencing major cardiovascular events (such as heart attack or stroke) or adverse pregnancy outcomes (low birth weight and pre-term delivery). So perhaps it's not surprising that a growing body of evidence suggests the two diseases are related.
