If you've ever felt a flash of guilt in the dentist's chair because you "forgot" to floss again, you're not alone. Flossing has become the poster child for dental discipline, the thing we all know we should do and rarely do consistently. But here's some good news: the string itself was never the real goal. The goal is cleaning between your teeth, and there's more than one way to get there.
What the research actually shows
Studies on flossing have a mixed reputation, and some headlines a few years back suggested flossing "doesn't work." That's an oversimplification. What the research really shows is that string floss specifically is hard to use correctly and consistently, so studies that measure it as a standalone habit often show modest results. That's a statement about human behavior, not about whether cleaning between teeth matters.
Plaque builds up in the tight spaces between teeth and along the gumline, areas a toothbrush simply cannot reach no matter how well you brush. When that plaque is left undisturbed, it hardens into tartar and irritates the gums, which is how gum disease gets its start. The evidence is clear on that part: removing plaque from between the teeth reduces gum inflammation and helps prevent cavities from forming in those tight contact points. The open question has always been which tool gets people to actually do it, night after night, for years.
Why the tool matters less than you think
String floss, floss picks, interdental brushes, water flossers — each one can do the job. They work differently and some are better suited to certain mouths (tighter contacts may call for thinner floss, wider gaps may respond better to an interdental brush, and people with bridges or braces often do best with a water flosser or a specific pick designed for their situation). But research comparing these tools consistently points to the same conclusion: the best tool is the one you'll actually use correctly, every day, without dreading it.
This is why we tend to steer patients away from a one-size-fits-all recommendation. Telling someone who hates string floss to "just floss more" is a bit like telling someone who hates running to "just run more." It's not a motivation problem, it's a fit problem. Once we find a tool that fits your hands, your schedule, and the specific spacing of your teeth, the habit tends to follow naturally.
Finding the interdental tool that fits your life
A few things worth knowing as you sort out what works for you:
- Floss picks are a great entry point if traditional string floss feels awkward or you struggle with hand dexterity. They're less flexible around curved tooth surfaces, but for many people that tradeoff is worth it if it means the habit actually happens.
- Interdental brushes (the small brushes with a wire and bristles) are often easier for cleaning around bridges, implants, or slightly larger gaps between teeth. They can reach spaces that floss glides past without disturbing anything.
- Water flossers use a pressurized stream to flush out debris and are popular with people who have braces, permanent retainers, or joint issues that make manual dexterity difficult. They're not a universal replacement for physically disrupting plaque, but for many mouths they do the job well.
- Traditional string floss is still excellent when used correctly, curved into a C-shape against each tooth rather than just snapped straight down. If you already have the technique down, there's no need to switch.
None of these is objectively superior for every person. What matters is that plaque gets physically removed from between your teeth on a regular basis, and that you're not so frustrated by the process that you skip it.
Building a habit that sticks
Most people who successfully build an interdental cleaning habit do a few simple things differently. They keep the tool somewhere visible, next to the toothbrush or by the sink, rather than tucked in a drawer. They attach it to something they already do every day, like right after brushing at night, so it doesn't require a separate decision each time. And they give themselves grace on imperfect days rather than treating one missed night as a reason to quit for a month.
It also helps to know your own mouth. If you consistently get food stuck in the same spot between two molars, that's useful information. A quick pass with an interdental brush in that one spot, even on a rushed day, is far better than skipping cleaning altogether because you don't have time for the full routine.
When to loop in your dental team
If you're not sure which tool makes sense for your teeth, or if certain areas bleed every time you clean them, that's worth mentioning at your next visit. Bleeding gums are usually a sign of inflammation that responds well to consistent cleaning, not a reason to avoid the area. We're happy to show you technique in person, recommend a tool suited to your spacing, and check how your gums are responding over time as part of your regular preventive care visits.
The bottom line is simple: don't get hung up on doing it the "right" way with the "right" tool. Get hung up on doing it, period, with whatever tool makes that realistic for you. If you'd like some guidance on what might work best for your teeth, we're glad to talk it through.
