Most customers will have great results with any of our THIN woven floss heads. Choose from Gray, Pink, Emerald, or Lilac colors in our untreated THIN floss.

For an added enamel-strengthening nano Hydroxyapatite benefits in a THIN floss, opt for our Blue nHA THIN floss heads.

If you have tight teeth, we think you'll love our new SMOOTH floss! It's specially designed to glide into snug spaces more easily.

If you have braces, you can use our special Braces floss heads! Once braces are off, you can easily transition back to a standard floss head style - all head styles and colors are interchangeable on all models of Slate flossers!

Our floss is ultra-high molecular weight polyethylene woven floss, which makes it highly durable! It is not coated or waxed, and it does not contain any PTFEs, PFAs, teflon, or other chemicals.

You can rest assured that our floss is TOXIN FREE!

About one week!

Slate floss heads are reusable (like your toothbrush!) Just rinse and allow to dry after each use, and change out weekly (for regular, daily flossers) for best results.

Those with tight teeth or a lot of dental work may experience some fraying due to increased friction on the floss. We recommend switching to our new SMOOTH floss heads or swapping out the floss head every 3-5 days if needed.

Those that floss more casually might not need to change floss heads as often!

Use our "Roll & Sweep" technique to get the longest use out of your floss heads!

For consistent, daily flossers, a box of 20 floss head refills should last about 20 weeks, or 4-5 months!

If you sign up for a subscription for floss head refills with your purchase, you can customize the frequency of your refill shipments based on your needs!

YES! The new rechargeable flosser has an IPX7 rating! This scale ranges from 0 (no protection) to 8 for the highest level of protection. An IPX7 rating ensures that the device can be submerged in water up to 1 meter for 30 minutes without any damage.

You can safely use your Slate Electric Flosser in the shower if you'd like!

Ethically sourced from 5% nano, nHa is a natural mineral that has remineralizing effects on enamel. We use this as a natural substitute to fluoride! It helps combat the negative effects of demineralization.

Our braces/ortho floss heads are specially designed to allow you to floss easily, with one hand, and only one device!

The slim arms on the braces floss heads go between the wire and the tooth, while the silicone brushes on the sides clean debris away from the brackets.

To remove a floss head, place your thumb on the back of the neck just below the tongue scraper and press down firmly on a hard surface until it pops off.

To connect a new floss head, slide the top of the flosser neck up through middle of the floss head and press firmly on the back of the tongue scraper until it snaps in on both sides (make sure the interacting logos on the flosser and the floss head are both pointing upward).
