People with poorly controlled diabetes are more susceptible to dental problems. They are more likely to have infections of their gums and the bones that hold the teeth in place, because diabetes can reduce the blood supply to the gums. In addition, high blood sugar may cause dry mouth and make gum disease worse. The decrease in saliva can cause an increase in tooth-decaying bacteria and plaque buildup.
When a person with diabetes has good blood sugar control, there's no increased risk of dental problems.
If you have diabetes, you probably know the warning signs of low blood sugar, or hypoglycemia. "It's been described best as a little like the feeling you get when you're sliding on ice in a car: panic, rapid heart rate, [and] sort of a sense of doom," says John Buse, MD, PhD, professor of medicine, chief of the division of endocrinology, and executive associate dean for clinical research at the University of North Carolina at Chapel Hill School of Medicine.
