There are varying levels of gum disease, according to the National Institutes of Health, ranging from gingivitis to chronic periodontitis. And they can affect more than just your mouth. The American Academy of Periodontology states that the inflammation from gum disease has been linked to heart disease, diabetes and rheumatoid arthritis. Other studies have found a potential connection between chronic gum disease and erectile dysfunction. And although there isn't a clear cause-and-effect relationship between the two, a nationwide study in Taiwan found that men with erectile dysfunction were more likely to have been diagnosed with chronic periodontitis than a randomly selected control group.
