Is there a link between periodontal disease and diabetes?

Research has suggested that there is a link between diabetes and gum disease. People with diabetes are more likely to have periodontal problems, possibly because people with diabetes are more susceptible to contracting infections. In fact, periodontal disease is often considered one of the major complications of diabetes. Interestingly, the relationship between the two conditions goes both ways; just as diabetes can increase a person’s chance of developing periodontal disease, research suggests that efficient and effective periodontal hygiene may positively affect blood sugar levels.
