For as long as i can remember everyone from my mom, to dentists, to health departments have always said daily flossing must be part of your daily oral hygiene habits if you want to avoid cavities and gum disease etc. Well turns out it may not be that important since the US Department for Health and Human Services is no longer recommending it due to insufficient proof that it actually helps.
The Associated Press did and investigation and asked the department for evidence that flossing helps and found
“When the federal government issued its latest dietary guidelines this year, the flossing recommendation had been removed, without notice. In a letter to the AP, the government acknowledged the effectiveness of flossing had never been researched, as required.
The AP looked at the most rigorous research conducted over the past decade, focusing on 25 studies that generally compared the use of a toothbrush with the combination of toothbrushes and floss. The findings? The evidence for flossing is “weak, very unreliable,” of “very low” quality, and carries “a moderate to large potential for bias.” [AP]
I’m pretty sure most experts will still recommend you floss though.
