ONE WEEK! (3-5 DAYS FOR THOSE WITH TIGHTER TEETH)

Replace floss heads weekly! Those with tight teeth might need to replace floss heads every 3-5 days. Use our "Roll & Sweep" technique to get the longest use out of your floss heads!

Slate floss heads are reusable (like your toothbrush!) just rinse & dry after each use, and change out weekly.

Those with tight teeth might need to change them more frequently.

Those that floss more casually might not need to change them as much!

20 WEEKS! (4 to 5 months)

If you have tighter teeth, you might want to order every 3 months.

We use woven floss with 450 strands. It is not coated and doesn’t contain any chemicals. It is ultra-high molecular weight polyethylene, and it is teflon-free.

TOXIN FREE! No PTFEs, PFAS, wax, or chemicals!

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.

YES! Both Slate Electric Flossers can be used in the shower.

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.

The Classic Grey, Pink, Green and Ortho Royal Blue floss heads do not have any flavors, are not coated and don’t contain any chemicals.

They are ultra-high molecular weight polyethylene, and they are teflon-free.

The light blue classic floss head has all natural nano-hydroxyapatite to help restore your teeth’s enamel.

The Slate Electric Flosser cannot work with a permanent retainer at this time. You can still use it on your molars, where most cavities form!

The slim arms on the floss head go between the wire and the tooth.

The Slate Electric Flosser, at this time, cannot work with a bridge. However, stay tuned, as this is in the works! 

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).

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.

Please be aware of the blue plastic label while changing the batteries. First look to see if the blue shim is stuffed in the top of your unit when changing the battery. There is a chance the blue shim stayed in the flosser during the changing of batteries and got shoved up to the top of the unit, preventing the proper electrical connection. To prevent this from happening to you, please make sure that when you change the battery, the blue shim comes out and you replace the current batteries with Duracell, Kirkland, or Makers Mark batteries.

If, after you have done the steps above and the button still will not turn on, please email us at support@slateflosser.com and we will exchange your button or product free of cost.
