A twin study recently published in the
Journal of Periodontology found that daily flossing combined with tooth and tongue brushing, significantly reduces the amount of
periodontal disease-causing bacteria in the mouth
The study was carried out at New York University and included 51 sets of twins between the ages of 12 and 21. Each twin set was randomly assigned a two-week treatment regimen with one twin brushing with a manual toothbrush and toothpaste and the other brushing with a manual toothbrush and toothpaste and
flossing. At the end of the two-week trial, samples were taken from each pairs of twins and compared for levels f bacteria commonly associated with
periodontal disease. The result showed that those twins who did not floss had significantly more bacteria associated with periodontal disease in comparison with his/her counterpart who had flossed.

According to the study's authors, only a small number of studies have reported on the clinical effectiveness of flossing for plaque removal and the
promotion of healthy gums. Commenting on the study, Dr. Kenneth Kornman, editor of the
Journal of Periodontology, said: "Twins tend to share the same or similar environmental factors such as dietary habits, health, and life practices, as well as genetics. In this case the only difference was flossing and the outcome was significant."
Dr. Susan Karabin, former president of the American Academy of Periodontology, adds: "Patients tend to think that flossing can't possibly make that much difference. But this study demonstrates flossing can significantly reduce the amount of periodontal disease-causing bacteria, even after just two weeks."
