The French Union for Oral Health (UFSBD) and many dentists recommend flossing after evening brushing, yet only 11% of French adults report using it regularly. Associated Press journalists delved into the evidence by reviewing 25 studies comparing brushing alone versus brushing plus flossing.
Key findings? An analysis of studies from the past decade shows dental floss has weak, often uncertain benefits. A 2015 study highlighted its lack of impact, while the sole 2011 research claiming reduced gum inflammation faced heavy criticism from periodontal experts.
This conclusion may be premature, as many studies involved small groups or short durations—insufficient for diseases that develop over years. Associated Press spoke with Wayne Aldredge, president of the American Academy of Periodontology. He acknowledges the limited evidence but still endorses flossing to combat gum disease, noting clearer benefits in at-risk groups like smokers and diabetics.
Until more robust research emerges, experts unanimously agree: Brush twice daily for two minutes to maintain optimal oral hygiene.
