When you find a flossing tool you actually like using, the last thing you want is confusion about which replacement heads you need. Slate makes things simple: every Slate flosser uses the exact same floss head. Whether you’re using the full-size Slate Electric Flosser at home or tossing the Slate Mini in your bag for on-the-go cleaning, one universal floss head fits them all.
But compatibility is only part of the story. The Slate floss head is packed with smart design details that make flossing easier, cleaner, and more comfortable than anything you’d get from standard floss picks or other electric flossers. Here’s what makes Slate different.

Meet the Slate Floss Head
The Slate floss head might be small, but it’s designed with the same care and precision you’d expect from a premium personal-care tool. Here’s what’s inside:
• Non-toxic woven floss
If you’ve ever had floss break or fray (especially between tight teeth), you know how annoying it is. Slate saves you from that frustration with durable woven floss that stays strong from start to finish. For optimal results, replacing your floss head weekly is ideal. Plus, our floss contains no wax, PFAS, or PTFE. So you can feel confident in the quality and safety of your dental tool.
• Gentle gum bushes
On the inner corners of each floss head, you’ll find soft silicone ridges. Those are called gum brushes (also known as gum sweeps). They’re designed to perfectly fit into the pocket between your teeth and along your gumline. It’s their job to disrupt and remove the plaque and biofilm that sticks to your teeth. You might be thinking, ‘Isn’t that what my toothbrush does?’ Well, yes and no. Your toothbrush cleans every surface it can reach, but it generally can’t access those tight corners where your teeth come together. That’s why our gum brushes are a game-changer. They lightly massage your gums and thoroughly clean the spots your toothbrush missed.
• Tongue scraper
Every Slate floss head also includes a built-in, 3-row tongue scraper on the back — a small but powerful feature most people don’t realize can make a huge difference in their oral health. Your tongue is one of the biggest collectors of bacteria in your mouth, often resulting in bad breath. Using a tongue scraper daily helps remove that buildup in just a few quick passes. As soon as you're done flossing, just flip the flosser over and give your tongue a gentle scrape. It’s fast, effective, and helps keep your breath fresher throughout the day.
• Easy snap-on attachment
Every Slate Flosser — the full-size Electric Flosser, the Mini, and future models — uses the same simple snap-on connection. No guessing, no wrong version, no frustration. If you’re confused about how to detach and reattach floss heads, click here to watch a quick tutorial from our founder, Brynn!
Universal Compatibility: One Head Fits All
We didn’t want customers juggling multiple replacement types or trying to remember which flosser they bought two months ago. So, we built our new Mini Flosser to be compatible with the original Slate floss head! That means:
-
One refill is all you need
-
One box works for every Slate device
-
Switching between devices is totally seamless
Have the Electric Flosser at home and the Mini in your car, gym bag, or travel kit? Great! You only need one kind of refill for both.
This makes routines easier and helps you stay consistent, which (as every dentist will tell you) is the real secret to healthier gums and cleaner teeth.
Why This Makes Flossing So Much Easier
When your tools are simple, reliable, and comfortable, you’re more likely to floss every day. Slate’s universal floss head helps you:
-
Build a routine you can stick to
-
Floss comfortably with less effort
-
Get a better clean in less time
-
Stay consistent, whether you’re at home or traveling
At the end of the day, the Slate floss head isn’t just compatible — it’s thoughtfully designed to make flossing something you actually want to do. No matter which flosser you’re reaching for, our floss heads are a guaranteed fit. With Slate, flossing is fast, easy, and incredibly satisfying. It’s the perfect tool to help you establish and maintain an oral care routine.
