Flossing helps remove the bacterial film that collects between teeth.2

THE SPACES YOU SKIP MATTER
Food caught between your teeth is easy to notice. Plaque is easier to overlook. Cleaning between your teeth is about removing both.

This was never a motivation problem
You already want to floss. It's everything that comes with it that gets in the way.
Every cleaning, you make the same promise: this time, you're going to floss.
You buy the good floss. You make it four days. Maybe five. Then you're tired, one missed night becomes a week, and the floss disappears into the drawer again.
The string slips. Your fingers ache. The back teeth feel impossible.
That isn't proof you don't care. An important habit has become a slippery, two-handed coordination task at the most exhausted point of your day.
Fifth Surface holds real floss on a powered handle, without the string wrapped around your fingers.
You still guide it and control the pressure. The idea is to take some of the hand work out of the step you keep meaning to come back to.
Useful reviews sharing why they hated flossing, what changed after Fifth Surface, & if they still reached for it after the novelty wore off.

The last two on the bottom left, I honestly hadn't properly cleaned those in about four years. Couldn't get both hands back there without my shoulder complaining. Now I can. I'll be honest with you, it was not pretty back there the first week.

Keeping it beside my toothbrush changed everything. Floss used to be hidden in a bathroom drawer, which made it very easy to forget. This stays visible where I already brush, so the reminder is built into the space. I finish brushing, pick it up and move on without negotiating with myself first.

I used to think of flossing as a completely separate chore that I would do later, which usually meant never. Fifth Surface sits next to my electric toothbrush and feels like the natural next step. That small shift has made the routine feel much more finishable.

My flossing routine usually disappeared when work got busy because string felt like one more fiddly task. The one-handed format removes the part I dreaded most. I do not need a burst of motivation anymore; I just need to reach for the handle.

HOW IT WORKS
Real floss, already held for you. Here’s how to make it part of your routine.
STEP 01 — PREPARE
The floss is already held between the prongs. Fit the head securely before switching on. No wrapping string around your fingers.
STEP 02 — SWITCH ON
Take a comfortable, one-handed grip and press the power button. Your fingers stay on the handle. You control where the floss goes.
STEP 03 — GUIDE
Ease the floss between your teeth. Gently guide it against one tooth, then the other, moving up and down along each surface. Never force it into your gums.
STEP 04 — FINISH
Work around the top and bottom teeth, including the backs of your last molars. Switch off, discard the used floss head, and clean the reusable attachment as directed.
If string floss already works for you every night, keep using it. Fifth Surface is for the person who wants real floss without managing loose string by hand.

Different tools solve different problems. Fifth Surface solves the string-floss handling problem without removing the floss.
What gets in the way, and what a handled format can offer.
Brushing is essential, but the areas between teeth still need their own cleaning step. What stands out about Fifth Surface is how the handled design addresses one of the most common barriers: the awkward positioning and finger wrapping required by traditional floss.
Most patients already understand that flossing matters. The challenge is finding a method they can realistically use—especially around the back teeth. Fifth Surface puts the floss on a guided handle, which may make that part of the routine feel more manageable.
Clinicians describe handling and access, not treatment outcomes. Ask your own dentist what is appropriate for your mouth.
Read the five-stars. Read the three-stars too. The right tool should survive an honest description.
Went in for my three month cleaning in August and she asked me what I'd changed. I told her. That's the first time in a good many years anyone's said something nice to me in that chair.
Standing at the sink for three or four minutes at the end of the day is not nothing at my age. I take it to the chair in my bedroom and do it there while the news is on. Small thing. Made it stick.
I didn't quit flossing on purpose. Wrapping that string around two fingers and pulling it tight got to where I just couldn't do it anymore, and I felt a bit silly saying that out loud to anyone. This one I hold in one hand like a toothbrush. That's the whole difference for me.

We bought a water flosser maybe five years ago. Filling it, spray all over the mirror, my wife complaining about the counter. It's in the hall closet now. This one sits out and I actually use it, which is more than I could say for the other thing.
My left hand doesn't cooperate anymore and string floss was finished for me a long time ago. This works with the one hand I've got. I do wish the head was easier to snap on, my fingers aren't quick, but I manage it.
I brush twice a day, so I assumed my mouth already felt clean. After my first full use, I understood the difference between brushed and finished - there was nothing caught between my teeth, and that immediate feeling made me want to use it again the next night.
My biggest issue was never understanding why floss needed both hands inside my mouth. Fifth Surface felt more natural because I could hold it like a toothbrush and guide actual floss with one hand. I needed a minute to learn the angle, but the basic idea clicked quickly.
I expected an electric flosser to be complicated, but it was surprisingly straightforward. Once I slowed down and guided the floss instead of forcing it, the rest of my mouth became much easier. It still feels like real flossing, just with far less finger work.
The front teeth were simple right away, while the back took a few attempts to figure out. By the end of the first use I had a much better feel for the angle. I appreciate that it makes flossing more manageable without pretending there is nothing to learn.
With regular string, I rushed through the front and quietly skipped the very back because my hands could not get into a comfortable position. The handle gives me a steadier grip and lets me approach those teeth more deliberately. My routine finally feels complete instead of almost complete.
Reaching my molars with string meant wet fingers, tight cheeks and losing tension halfway through. Using one hand is a much bigger improvement than I expected. I can concentrate on where the floss is going instead of trying to control both ends of it.
I used to work by feel and usually gave up near the back. Being able to see where I am guiding the head makes the last few teeth feel less like guesswork. I still move slowly, but I feel far more in control than I ever did with loose string.
This is much easier for me than wrapping floss around my fingers, especially across most of my mouth. The furthest molars still require a careful angle and a little practice. It is not magic, but it removes enough of the awkwardness that I no longer skip them automatically.
Several of my contacts are tight, which was the main thing I worried about before ordering. I go slowly and guide the floss rather than pressing down hard. What I like is having the floss held steady so I can focus on the contact instead of keeping tension with my fingers.
Most of my teeth are easy with Fifth Surface, but I have two contacts that are extremely close together. Those still take more time and a gentler approach. The handle is easier for me to control than loose floss, but tight teeth do not suddenly stop being tight.
Traditional floss sometimes slipped through a tight contact so suddenly that it hit my gums. With the floss already held and tensioned, I feel like I can guide the movement more deliberately. I still use gentle pressure, but the whole process feels calmer and more controlled.
I bought this hoping tight contacts would become effortless. They did not, but the handle makes them less frustrating because I am not also fighting slippery string. Once I stopped rushing and learned the angle, it became a useful part of my routine.
I was always good at starting to floss and terrible at continuing. After three or four nights, the string would disappear back into the drawer. Fifth Surface feels like one simple step instead of a separate project, so it has been much easier to repeat.

I have a crown and was nervous about using anything new near it, so I asked my dentist before trying the device. I use gentle pressure and never force the floss. The handle gives me a steadier grip than loose string, which helps me feel more deliberate around that area.
Older fillings made me cautious because I have always worried about floss catching or pulling. My hygienist showed me where and how to guide it for my mouth. I like that I remain in control of the position and pressure instead of the device pretending to do everything for me.
Fifth Surface works well for the regular contacts my dental professional approved, but I still use a separate tool underneath my bridge. I actually appreciate that distinction. It makes normal flossing easier without claiming to replace every specialized recommendation for dental work.
I have a mix of natural teeth and older dental work, so I brought the device to an appointment before using it everywhere. Once I knew which areas were appropriate, the one-handed grip felt much easier to manage. Anyone with dental work should get advice for their own mouth.
The product is easier than string for me, but my first attempt was slower than the ads made me expect. The front teeth were simple and the back teeth took practice. After a few uses I became more comfortable, but clearer first-use guidance would make the experience better.
I like the handle and can use it comfortably across most of my teeth. However, two very tight contacts remain difficult, and the head feels awkward around my last molar. I still use the device, but I also keep regular floss for the areas where it works better for me.
Thank you for describing this so clearly. Fifth Surface uses real floss, so very tight contacts and individual mouth shape can still affect the experience. We never recommend forcing the floss, and the 90-day home trial is there for anyone who decides the fit is not right for their mouth or routine.
I am very happy with the one-handed design and use it regularly. My only complaint is that the first-use instructions made the back molars look easier than they felt in practice. A longer, unedited demonstration with multiple mouth angles would be genuinely helpful.
I love not wrapping string around my fingers, and the powered movement makes the process feel less tedious. You still have to guide the floss around each tooth and pay attention to pressure. That is not a flaw, but it is worth understanding before buying.

Built for anyone who has bought the good floss, made it a few days, and put it back in the drawer.
We fail because of the arithmetic we do standing at the sink, weighing the effort against how tired you are. Cut the time and the arithmetic stops happening.
The handle guides the whole routine. You hold it like a toothbrush, move along the arch, and the angle you need at the back molars is the angle the handle already gives you.
The device supplies the movement. You choose the gap and the pressure. That's the whole job left.
Floss that lives in a drawer, stops getting used. his stands on the counter, charged, in the row of things you already reach for without thinking.

Including the blunt ones. If the honest answer is maybe not, that is what it says.
Maybe not. Tight contacts can shred floss, and that's true of ours as well as string. If your teeth are very close, this is the honest risk. That's part of why the guarantee is 90 days.
No. A Waterpik sprays water. This holds real floss and moves it between your teeth. Different tools that do different things.
This won't get under the wire. Nothing that isn't threaded will. You'd still need a threader for that section.
Lots of people use it with dental work. Go gently, especially the first few times, and ask your dentist what they'd recommend for your situation.
Bleeding when you start flossing is common and it usually settles down as your gums get healthier. But we're not your dentist. If it keeps happening or it hurts, go get it looked at.
There's an LED at the head. It lights the gap you're working in, which matters because the back of your mouth is dark and you've never been able to see what you were doing back there. It won't improve your technique on its own — that's the vibration's job.
50 in the box. Most people use about 1 per session, so we publish that number rather than the flattering one — you'd work it out anyway.
