award-winning, and making headlines
LET OUR CEO, BRYNN SHOW YOU HOW IT'S DONE.
Up to 3 speeds and 14,000 vibrations per minute help break up plaque and dislodge particles from tight spaces.
Roll it in - don't snap. Once the floss is between your teeth, don’t just move the floss up and down—use a slight curved motion to clean around the base of the tooth.
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.
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.
Each floss head is designed to be rinsed and reused for up to a week, just like a toothbrush. That means less waste than disposable floss picks and an easier routine to stay stocked on.
"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!"
"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!"
"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!"
"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."
"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!"
Gum disease has been linked to increased systemic inflammation, which is associated with higher cardiovascular and stroke risk. Some studies suggest daily flossing may reduce stroke risk by up to 44%.
Emerging research has shown an association between chronic gum disease and increased dementia risk. Daily habits like flossing can help reduce oral bacteria and inflammation before they become bigger issues.
The other 40% — the space between your teeth and along your gumline — is where plaque builds up, bacteria thrive, and inflammation quietly starts. And your toothbrush simply cannot reach it. The Slate Electric Flosser was designed specifically for that 40%.

Our Ortho/braces floss heads are specially designed to allow customers with traditional bracket and wire braces to floss easily and effectively, with one hand, and only one device!
The slim arms on the Ortho floss heads go between the archwire and the tooth surface, allowing the floss to extend down to the gums, while the silicone brushes on the sides clean debris away from the brackets.
The braces heads are not intended to be used for those who do not have braces.
HOW TO FLOSS WITH BRACESOur floss is ultra-high molecular weight polyethylene (UHMWPE) woven floss, which makes it highly durable and non-toxic. None of our floss is coated or waxed, and it does not contain any PTFEs, PFAs, or other chemicals.
Our Blue and Mint floss heads use woven floss that is infused with nano Hydroxyapatite (nHA) for remineralizing benefits. The Mint is also infused with subtle natural mint flavor. All other floss head colors are unflavored.
You can rest assured that our floss is PTFE and PFAs free!
The short answer: 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 extremely tight teeth or a lot of dental work may experience some fraying due to increased friction on the floss. We recommend using one of our Smooth floss head options and/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!
We recently changed our floss head refill packaging to 12-pack, 24-pack, and 3-pack (sample) options.
With the intended one week per floss head usage rate, you should get about 3 months of use from a 12-pack and around 6 months of use from a 24-pack. We made the packaging switch to be more in line with how often dentists recommend changing out your toothbrush (every 3 months).
If you sign up for a subscription for floss head refills, you can customize the frequency of your refill shipments based on your needs!
YES! The Slate Pro has an IPX7 rating and the Slate Origin has an IPX5 rating. This scale ranges from 0 (no protection) to 8 for the highest level of protection.
Both of our electric flossers (Pro and Origin) are safe to use in the shower if you’d like.
We do recommend that you allow the floss head to fully dry between uses to prevent bacteria growth.
To remove a floss head, place your thumb on the back of the neck of the flosser, just below the tongue scraper and press down firmly on a hard surface until it pops off.
HOW TO USE VIDEOTo 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).
HOW TO USE VIDEOYes! It is very important to continue flossing regularly in areas with veneers or crowns. If you have any sharp edges or areas that are catching on the floss string, talk to your dental professional about smoothing those out!
Here's a great blog post about why using the Slate Electric Flosser is perfect for crowns and veneers:
