Before buying a Slate Electric Flosser, most customers have never used an electric flosser before, so it’s completely normal to wonder how it works. Slate is designed to make daily flossing easier, more effective, and more sustainable, especially for people who want a routine that actually sticks. Just like an electric toothbrush head, Slate floss heads are built to be reused safely. They’re specifically engineered to be rinsed, air-dried, and used multiple times, helping you floss more consistently, reduce waste, and feel confident in your oral care routine.
With Slate, you’re not sacrificing cleanliness. You’re upgrading your routine.

Reusing Floss Heads: Think of It Like Your Toothbrush
When you brush with an electric toothbrush, you don’t toss the brush head after one use. Instead, you rinse it, let it dry, and then use it again each day until it’s time to replace it. The same principle applies to the floss head on your Slate Electric Flosser.
Slate floss heads are designed to be multi-use and durable, lasting about a week with regular daily flossing. After each use, they should be rinsed thoroughly, allowed to dry, and replaced on a routine schedule. Rinsing during and after flossing washes away the plaque and food debris that your floss extracted from between your teeth. Then, allowing the floss head to fully air-dry between uses eliminates the moisture bacteria need to multiply. Dry environments naturally limit bacterial growth, which is why air-drying is such an important step in dental tool maintenance.
Floss Head Daily Care Checklist
-
Rinse thoroughly with water after each use
-
Remove visible debris immediately
-
Allow the floss head to fully air-dry between uses
-
Store in an open, dry environment
-
Replace with a new floss head weekly or as needed
This approach isn’t unique to Slate; many oral hygiene products are designed to be rinsed and reused within a reasonable time frame. Because dry conditions limit bacterial growth, and regular plaque/debris disruption (rinsing, brushing, flossing) reduces the accumulation of bacteria, you can feel comfortable and confident using your Slate reusable floss head daily.
Slate’s Design Makes Reuse Safe and Hygienic
It’s true that some dental-health sources caution against reusing traditional string floss, primarily because string floss can fray, lose effectiveness, and physically drag bacteria around instead of removing it. Fortunately, concerns about reusing string floss don’t apply to Slate floss heads.
Our floss heads are engineered to be reused safely and effectively:
✅ Non-toxic woven floss: Unlike many floss picks with wax or coatings, Slate floss heads are free of harmful chemicals like PFAS or PTFE, meaning you’re rinsing and reusing material that’s been deliberately designed to be safe in your mouth.
✅ High-quality construction: Slate’s woven floss includes over 400 strands built to handle repeated use and vibration without breaking down quickly, so it stays smooth and effective between refreshes.
✅ Weekly replacement is recommended: For most users, changing the floss head once a week ensures you’re not overusing any single piece and keeps your routine hygienic and effective. If your teeth are especially tight or you floss more often, you might choose to replace it a bit sooner, but weekly is a great general timeline.
Good for Your Teeth and the Planet 🌍
One of the biggest environmental benefits of the Slate Electric Flosser is that our reusable floss heads eliminate the need for multiple single-use plastic floss picks. In fact, one user can prevent almost 700 floss picks from ending up in landfills each year by switching to a Slate Flosser.
With our new mini manual flosser, you can even have the convenience of a small, portable flosser with the added effectiveness of a Slate reusable floss head. All of Slate’s floss heads are compatible, meaning you can use the same floss heads on the mini flosser and the electric flosser. By switching to Slate, you’re not just cleaning your mouth; you’re also making a more sustainable choice for your oral health and the planet.
