Gray Floss Heads

The SLATE Electric Flosser™ stands out as the only 3-in-1 electric flosser on the market. It combines high-grade floss, sonic vibrations, a tongue scraper, and the unique Gum Sweep technology to give you a deeper clean. Its standout feature is the patent-pending Gum Sweeps™, which no other flosser has. This unique technology not only removes plaque and food particles but also massages gums, promoting blood flow and healthier gums. Plus, SLATE Electric Flosser is toxin-free, containing no wax, Teflon, PFAS, or PTFEs, making it safe choice that’s better for both your health and the planet.

SLATE was founded by Dr. Danny and Brynn Snyder, a husband-and-wife duo passionate about transforming oral care. After recognising how challenging traditional flossing can be, Dr. Snyder spent nine months developing the SLATE Electric Flosser. Designed for everyone—children, seniors, individuals with braces, or dexterity issues—it makes flossing fast, easy, and effective. Today, with over 25,000 satisfied customers and 500+ dental hygienist reviews, SLATE delivers healthier, cavity-free smiles with professional-level care at home.

1. Press the blue button on the bottom of the flosser to turn it on.
2. Slide the floss between your teeth using our "roll and sweep" method to avoid breaking your floss.
3. Move the floss head from the front to the back of your teeth, allowing the Gum Sweeps™ to scrub the teeth and massage the gums.
4. Use the tongue scraper 3-5 times when you are finished flossing to remove the bacteria you disrupted! Rinse the floss head thoroughly and allow it to dry.
5. 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 them!
