You may have type 2 diabetes
Red, swollen gums that may bleed are the hallmarks of periodontal disease—an incredibly common condition that affects more than 47 percent of Americans 30 and older and more than 70 percent of adults 65 and older, according to the CDC. Periodontal disease is brought on by bacteria in the mouth that infect the tissues and create plaque. “Diabetes makes periodontal disease worse,” says Paulo Camargo, DDS, professor of periodontics and associate dean for clinical dental sciences at UCLA School of Dentistry. “Periodontal disease can also make the blood sugar more difficult to control.” Research shows that diabetes is a major risk factor for periodontitis, a more serious form of periodontal disease that can damage soft tissues and destroy the bone that supports teeth. In fact, people with diabetes are three times more susceptible to developing periodontitis than those who aren’t diabetic. “If gums bleed a lot and are swollen or the patient is having frequent abscesses or infections, the dentist might start to question if you have a family history of diabetes,” says Sally Cram, DDS, a periodontist in Washington, DC, and a spokesperson for the American Dental Association. Diabetes isn’t the only health problem associated with periodontal disease: The disease, which triggers a harmful, inflammatory response, is also linked to a higher risk of heart attack and stroke.
