The Great Flossing Debate: Essential Hygiene or Overhyped Habit?

A woman with a towel wrapped around her head smiles while flossing her teeth in front of a bathroom mirror, reflecting a healthy morning routine.

Did the news get it wrong? Why flossing is NON-negotiable.

In 2016, a media storm erupted when an Associated Press article questioned the efficacy of flossing, claiming that the evidence for its benefits was weak. This sparked a heated debate, leaving many wondering: Is flossing really necessary, or is it just an overhyped habit? Let’s revisit the controversy, examine the evidence, and reaffirm why flossing remains a critical part of gum health—especially here in South Africa.

The Controversy: Where Did the Doubt Come From?

The flossing debate kicked off with a 2016 Associated Press investigation. It highlighted a review of studies that found “weak” and “unreliable” evidence supporting flossing’s benefits. Headlines screamed that flossing might be pointless, and suddenly, a cornerstone of oral hygiene was under scrutiny.

But there’s more to the story. The review itself was limited—it analyzed only a small number of studies, many of which were short-term or had small sample sizes. It didn’t account for the broader body of research or the real-world experience of dentists. Dental organizations, like the South African Dental Association (SADA) and the American Dental Association (ADA), swiftly pushed back, criticizing the review’s narrow scope and reaffirming flossing’s value. The media, however, had already fanned the flames of doubt.

The Evidence: Flossing Works

So, what does the science actually say? The evidence for flossing’s role in gum health is robust and compelling:

• Plaque and Gingivitis Reduction: A 2011 systematic review found that flossing, combined with brushing, significantly reduces gingivitis (gum inflammation) compared to brushing alone. Another study showed flossing removes up to 80% of plaque from between teeth—spots your toothbrush can’t touch.

• Prevention Over Time: Regular flossing stops plaque from hardening into tartar, which can lead to periodontal disease. In South Africa, where gum disease is a major cause of tooth loss, this preventive step is vital.

• Expert Backing: SADA and the ADA recommend flossing daily. Dentists consistently report healthier gums and fewer cavities in patients who floss regularly.

This isn’t just theory—it’s proven in practice. Flossing tackles the 40% of tooth surfaces brushing misses, making it a non-negotiable part of oral care.

Why the Doubt Emerged (and Why It’s Misplaced)

The 2016 review wasn’t entirely wrong to call out gaps in some flossing studies. Many were short-term or lacked the scale to draw definitive conclusions. But here’s where the doubt went off track:

• Media Misstep: The press ran with a sensational narrative—“Flossing Doesn’t Work!”—without explaining the review’s limitations. It wasn’t that flossing was ineffective; it was that some studies couldn’t fully prove its benefits in isolation.

• Missing Context: Oral health isn’t built on one study. It’s a cumulative picture of research, clinical outcomes, and decades of dental expertise. The review ignored this bigger picture.

Brushing alone isn’t enough—plaque hides between teeth, fueling gum disease and cavities. In South Africa, where dental care access can be patchy, especially in rural areas, flossing is a cheap, effective way to stay ahead of problems.

Busting the Myth: “I Brush Well, So I Don’t Need to Floss”

Think brushing twice a day is enough? Think again. Even the best brushing technique misses between your teeth. Flossing isn’t optional—it’s essential:

• Gum Protection: It removes plaque that leads to gum disease, a widespread issue in South Africa.

• Cavity Defence: Cavities often start between teeth. Flossing stops them before they begin.

• Breath Boost: Bad breath lingers when bacteria fester in tight spaces. Flossing clears them out.

Why It Matters in South Africa

Here, oral health challenges hit hard. SADA notes that many South Africans lack regular dental checkups due to cost or distance. Flossing is a simple, affordable habit that can prevent bigger issues—especially when a trip to the dentist isn’t always an option. From bustling Joburg to remote villages, it’s a small step with big impact.

The Bottom Line: Flossing Is Non-Negotiable

The 2016 media storm was a hiccup, not a revelation. Yes, some studies need improvement, but the evidence and expert consensus are clear: flossing keeps your gums healthy and your smile strong. Don’t let headlines sway you—keep that floss handy. Your teeth deserve it.
