If you’ve ever skipped flossing the night before a dental appointment and scrambled to catch up, you’re not alone, and you may have also seen headlines a few years back claiming flossing doesn’t actually do anything. So what’s the real answer? Here’s what dentists actually say.
Where the Confusion Started
Back in 2016, a few news outlets reported that there wasn’t strong scientific evidence proving flossing reduces cavities or gum disease. Those headlines spread fast, and a lot of people took it as permission to drop floss from their routine for good.
But the real story is more nuanced. The issue wasn’t that flossing doesn’t work, it’s that large, long-term studies on flossing are difficult and expensive to run, so the existing research wasn’t as robust as researchers would like. A lack of large-scale studies isn’t the same thing as proof that something doesn’t help.
So, Does Flossing Actually Do Anything?
Yes. Here’s why dentists still recommend it every day, in every appointment:
Your toothbrush can’t reach everywhere. Even with excellent brushing technique, bristles simply can’t clean between teeth or below the gumline where they touch. That tight space between teeth is one of the most common places plaque builds up and cavities start.
Plaque left behind hardens into tartar. Once plaque calcifies into tartar, only a professional cleaning can remove it. Daily flossing disrupts that buildup before it gets the chance to harden.
It helps prevent gum disease. Plaque sitting between teeth and along the gumline is a leading cause of gingivitis, the earliest stage of gum disease. Removing it daily is one of the simplest ways to keep your gums healthy long term.
Dentists can tell. It’s not just a talking point, dentists and hygienists can typically see the difference in gum health and plaque buildup between patients who floss regularly and those who don’t.
What If Regular Floss Isn’t for You?
Not everyone loves traditional string floss, and that’s okay, the goal is cleaning between your teeth, not the specific tool you use to do it. A few alternatives that work just as well when used consistently:
- Water flossers: great for people with braces, bridges, or limited dexterity
- Floss picks: a convenient option for on-the-go use
- Interdental brushes: small brushes designed for wider gaps between teeth
The best flossing method is simply the one you’ll actually stick with every day.
How Often Should You Floss?
Once a day is enough. Many people find it easiest to floss right before bed, so food and plaque aren’t sitting between your teeth overnight while your mouth produces less saliva to naturally rinse things away.
The Bottom Line
Flossing isn’t a myth, and it isn’t optional if you want to avoid cavities between your teeth and keep your gums healthy. It’s a small daily habit that fills the gap your toothbrush simply can’t reach.
