If you have diabetes, you are more likely than people who don’t have diabetes to have gum disease. Why? Again, inflammation may be partly to blame. And, those with diabetes are more likely to contract any infections, including gum disease.
If your diabetes is not under control, you are at even higher risk of gum disease.
Gum Disease and Dementia
Gum disease has also been found to increase the risk of dementia later in life.
Other researchers have found that periodontal problems may also be associated with milder cognitive impairment, such as memory problems that make activities of daily life more difficult. In a recent study, participants who had the worst gum disease scored the worst on memory tests and calculations.
