Feeling Guilty About Not Flossing? Maybe Theres No Need
For decades, the federal government not to mention your dentist has insisted that daily flossing is necessary to prevent cavities and gums so diseased that your teeth fall out.
Turns out, all that flossing may be overrated.
The latest dietary guidelines for Americans, issued by the Departments of Agriculture and Health and Human Services, quietly dropped any mention of flossing without notice. This week, The Associated Press reported that officials had never researched the effectiveness of regular flossing, as required, before cajoling Americans to do it.
In a statement issued on Tuesday, the American Academy of Periodontology acknowledged that most of the current evidence fell short because researchers had not been able to include enough participants or examine gum health over a significant amount of time.
The revelation has caused a stir among guilt-ridden citizens who strive to floss daily but fall short of that lofty goal. Among experts, however, it has been something of an open secret that flossing has not been shown to prevent cavities or severe periodontal disease.
The American Dental Associations website says flossing is an essential part of taking care of your teeth and gums. Last year, Dr. Edmond R. Hewlett, a spokesman for the group and a professor of restorative dentistry at the University of California, Los Angeles, said, Were confident that disturbing the bacteria in plaque with brushing and flossing is, indeed, beneficial.
Actually, thats only half proven: Brushing with fluoride does prevent dental decay. That flossing has the same benefit is a hunch that has never been proved.
If its any consolation, there is some mediocre evidence that flossing does reduce bloody gums and inflammation known as gingivitis. That Cochrane review found that regular brushers and flossers had less gum bleeding than people who only brushed, although the authors cautioned that the quality of the evidence was very low.
