LONDON, England: More than a third of UK adults in a study by periodontal health brand Corsodyl experience bleeding gingivae at least once a month when they brush their teeth and ignore it or simply brush more softly. The findings also showed that, while most participants recognised that diet, weight, family history, lack of physical activity and high blood pressure may all contribute to Type 2 diabetes risk, just one in ten knew that periodontal disease is associated with an increased risk of Type 2 diabetes.
