Bacteria That Causes Tooth Decay and Gum Disease is Killed by Flossing

A recent study reported in the Journal of Periodontology (Augsut, 2008) in a twin study, shows that flossing is beneficial and kills bacteria that cause tooth decay and gum disease. Investigators for the New York University College of Dentistry, performed a study using fifty-one pairs of identical twins, ages 12-21 y.o. For this research investigation, all of the identical twins used a manual toothbrush and toothpaste to brush their teeth and tongues. In addition, 1 twin from each pair also flossed their teeth as directed.

Two weeks later, the study investigators, obtains bacteria specimens from each of the study participants’ mouth. The results of the study showed that flossing had a significant effect on oral health, and significantly decreased the quantity of bad bacteria. Investigations using twin are potent, because they tend to have the same habits, and grow-up in the same household. Also, genetics do not influence the study results.
