The only extra dental tool you need

The World's Only 3-in-1 Floss Head

Every Slate floss head is three tools in one and is designed to be rinsed and reused for up to a week. That means less waste than disposable floss picks and an easier routine to stay stocked on.

Slate 3-in-1 floss head: woven floss, gum brushes, and tongue scraper

1 / 3

CHEMICAL-FREE WOVEN FLOSS

No PFAS, no PTFE, no wax. Just floss that's safe to reuse all week.

2 / 3

Tounge Scraper

Because a cleaner mouth is not just about your teeth. Slate’s built-in triple-row tongue scraper helps remove leftover bacteria and complete your routine in one tool.

3 / 3

Patented Gum Sweeps

The soft silicone gum brushes help massage and stimulate the gumline while sweeping away plaque and buildup. It’s one of the biggest reasons Slate feels different — and cleans more completely.

Three tools. One reusable floss head.

  • "My favorite thing about the Slate Electric Flosser is how it cleans embrasures with ease. A lot of my patients would benefit from a flosser like this because so many of them floss ineffectively by only going up and down. With Slate, I feel like I have to do way less work to get a better clean!"

    Dr. Brittany Baker DMD

  • "The Slate Electric Flosser is awesome! I love how the vibrations help the floss to get through the tight contacts of some of my teeth. The gum sweeps help really get every thing clean and the handle design makes the overall use very simple and convenient. I love the Slate Flosser and highly recommend it!"

    Dr. Jayson Wurtzbacher

  • "I love that you can actually reach the backside of the second molars! This device is a game changer for so many patients whom do not have the dexterity to floss with traditional methods. Also love the eco friendly aspect with reusable replacement heads!"

    Amanda O'Brien RDH

  • "I am a 37 year old dentist and have never been very consistent at flossing until now. The Slate flosser has been the one tool that finally helped me become a daily flosser. It does a fantastic job of cleaning my teeth, it is more comfortable than other options, and it sits right next to my electric toothbrush and makes it so easy to get into a good flossing routine. I have told all my staff to use this flosser."

    Dr. Chad Smith

  • "The Slate flosser is so great! I feel like the vibrations are super helpful at removing more plaque than traditional floss. I also love the long easy-to-hold handle!"
