The hygienist's advice to floss daily to prevent gum disease lacks hard evidence of benefits, a new investigation suggests.
The U.S. government has recommended flossing for decades. It was included in the 2010 Dietary Guidelines for Americans, which stated: "A combined approach of reducing the amount of time sugars and starches are in the mouth, drinking fluoridated water, and brushing and flossing teeth, is the most effective way to reduce dental caries."
In the 2015 version, that recommendation is no longer included.
The most recent rigorous research, focusing on 25 studies that generally compared the use of a toothbrush with the combination of toothbrushes and floss found that evidence for flossing is "weak, very unreliable," of "very low" quality, and carries "a moderate to large potential for bias."
A 2015 review published in the Journal of Clinical Periodontology also concluded "the majority of available studies fail to demonstrate that flossing is generally effective in plaque removal."
