Why should I have Healthy Gums? Healthy gums can reduce a person's biological age by up to 6.4 years. Why? Because "studies show that the presence of periodontal diseases, most common in people with tooth loss, actually affects longevity. The best of these studies, done at Emory University in conjunction with the Centers for Disease Control, indicates that people with gingivitis and periodontitis have a mortality rate that is 23% to 46% higher than those who don't." Keeping your gums clean and healthy may help reduce the risk of many illnesses, including heart disease.
