Dental Professional Reviews

Dr. Brittany Baker DMD
"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. Jayson Wurtzbacher
"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!"
Amanda O'Brien RDH
"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!"
Dr. Chad Smith
"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."
Casandra Hollis RDH
"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!"
Dr.  Mara Ganim
"Game. Changer. I can’t say enough good things about the Slate electric flosser! They nailed the convenience of the floss picks, but made it so much better! As a dentist the gum sweeps are my favorite part! That’s what makes this product stand out to me. They really clean the spaces in between your teeth and are super gentle! 10/10 would definitely recommend to family, friends, and patients!"
Dr. Emily Dennison
"I love how easy it is. My teeth feel amazingly clean after! I also love the gum sweeps and the tongue scraper! I always tell my patients that neglecting to clean your tongue is like mopping the floors and not deep cleaning the giant rug in the middle of your mouth."
Dr. Kevin Brown
"I love how easy it is to use and how clean my gums feel when I'm done with it. It's amazing!!!"
Sandra Sikimic RDH
"It's extremely convenient for anyone who finds string floss tedious! I personally love the gum sweeps. It's a brilliant feature! It just levels up what flossing already does for your gum health!"
Amber White RDH
"I love the Slate Flosser because it's super easy to use, and it's great for anyone who finds flossing challenging. Whether you have limitations or are undergoing orthodontic treatment, it's a game-changer. The simplicity and effectiveness make it an essential part of my oral care routine."
Lindsey Hesse RDH
"It is so easy to use! It's an amazing tool for everyone, but especially those with limited dexterity like children or elderly adults."

Slate Rechargeable Electric Flosser

Good product

Seems a little odd at first but you get the hang of it and it works great. I'm sure I'll be using it daily from now on and helping my gums stay healthy.

Slate Rechargeable Electric Flosser

Best Investment of 2025

I went from being a person who flossed once a week to a person who now flosses daily. I could never feel the difference with typical floss. The Slate flosser makes my mouth feel so clean that I wouldn’t dare leave the house before using it.

Best Gift Idea Ever. 10/10 No Notes

I got this set as a gift for my grandparents and my in-laws and they love it!! It has everything they need to get into the habit of flossing easily. I have the slate electric flosser and the mini already so this set is really just all of my favorite things combined!! So nice to have a box of floss head refills included and the process to subscribe for more refills is super easy. Can't recommend this product enough!

Slate Mini Flosser - BLUE
Ashley (Raleigh, US)
My New Favorite Self Care!!

I am absolutely in LOVE with the slate mini flosser. I have been loyal to the plastic floss picks forever but this is a game changer. I love how easy it is to bring to school, work, my car, or literally anywhere. I’m going to get one of these for all of my family members!

New Gray SMOOTH Floss Heads
Kathy R. (Springfield, US)
A learning curve

There definitely was a learning curve. In the beginning, there were a couple times when I tore up my mouth- actually ended up with a couple of sore places and even blood from the gum! After watching the video, the video is what changed how I flossed , and that made a huge difference. I enjoy using my flosser now. I think the flosser does do a better job than string flossing, so thank you!

Just tried the flosser for the first time and my teeth feel super clean. Ice tride a different electric flosser in the past and this is far superior.

Floss Head Cover - BLUE
KimberlyP (Alameda, US)
WHY wouldn't the product come with a cover??

First, let me say right off that I LOVE my Slate electric flosser. My gums don't bleed anymore! I take it everywhere!! But especially for the price of the unit, why would you not include a cover for the floss head?! There was a little band in the box that looked like a headband that *might* be a cover?? But I don't like how it squeezes the floss. I am debating buying the travel one only for the floss head cover, which is a waste, but it still less than buying the cover here + shipping. You seem to have thought of so many small details that make this flosser even better. Please consider including a cover! Thanks!!

Hi Kimberly, thank you for your feedback. We're so glad that you love your Slate flosser! We wanted to let you know that the new floss head covers are a brand new product that we *just* got in stock within the past couple of weeks and therefore weren't available previously. The band around the charging cord in the flosser box is not intended to be a cover. Our support team will reach out to you directly to assist further!

Head only lasts a for couple of flooses

The head broke after two flosses. Would like to try the thin floss head. Can you send me a sample?

Mark, we're sorry to hear that you've had trouble with a floss head only lasting for a couple of flosses. Our support team will reach out to you directly to troubleshoot and make sure you have the opportunity to try our new SMOOTH floss, which is designed to get into tight spaces more easily!

Feel fresh and clean

This flosser is AMAZING! Our teeth have never felt so clean, it is like coming home from a dental cleaning, but without the sore gums!
We are SUPER grateful for our Slate flosser!
ALSO- so grateful for the orthodontic heads for our kiddo with braces.

We can't thank you enough for this amazing feedback! We are so glad that your family is seeing amazing results and enjoying the special ortho head option for braces! Keep up the amazing work flossing with Slate!

Never going back to regular floss

Only been using it for a week and already using it religiously. Makes it so easy to get my back teeth and way cleaner than using regular floss. So good I’m buying some for family members for christmas

The only way I floss daily

The only way I floss daily

This time it works. The first one i bought you had to change the battery inside if the handle and a typical battery would not fit. So it was trash after the battery died. Im glad they are rechargeable now!

Thanks slate!

I have tight teeth and a gag reflex. My slate flosser has changed my oral care for the better. The dental hygienist is always amazed at how clean my teeth are and how healthy my gums look. They always ask me what I’m doing and I tell them, “just using my slate”.

Thank you so much for sharing, Val! We love to hear that you're getting great results from using your Slate flosser and we're very thankful that you're spreading the word!

Product is excellent!

Thanks for your great feedback!

Travel case is a bit large for the Flosser. It would be a better fit to just accomodate if case was mre the size of the Flosser with a place to secure several Flosser heads. What is the outside pocket intended to accomodate?

Floss Head Cover - BLUE
Paul R. (Lakewood, US)
At last! Now i can throw out my tinfoil cover that I had fashioned for that purpose!

Excellent design , fits perfectly!

Thank you, Paul! We're so glad you love the new floss head covers as much as we do! Happy flossing!

a step up in flossing

It took a bit to learn how to use it, but the flosser is very effective. Effortlessly helping with dental hygiene. I find the heads don't last as promised, as I need to replace them twice as often as predicted. Glad I found and bought the flosser.

Thank you for your review! We sincerely appreciate the feedback and hope that you are able to get a little more lifespan with the new SMOOTH Gray floss heads on your most recent order. The SMOOTH floss is designed to get into tight spaces more easily and often reduces the amount of fraying and breakage. We're so glad that you're loving your flosser and are always here to help if you need any assistance!

So much better than disposable floss picks!

Loving the new Mini flossers so much - so convenient. I need one in my car, one in my purse, and one at home! Colors are all so cute and I love that they use the same Slate floss heads as the electric flosser!

Thank you for sharing your positive experience with our Slate Mini Flosser in LILAC! We are thrilled to hear that you find it more convenient than disposable floss picks and that you love the variety of colors. Thank you for your support and happy flossing!

A Small Flosser That Makes a Big Difference

I was impressed with the Slate Mini Flosser. The design is compact, easy to use, and the angled handle makes reaching back teeth simple. The floss is strong, doesn’t shred, and gives a great clean. I tried the samples myself and shared them with a few patients—everyone loved them. I’ll definitely be recommending the Slate Mini Flosser in my practice.

Thank you for your wonderful feedback, Dr. D.! We're so thrilled to hear that you're a fan of the new Mini Flosser and will be recommending it to your patients. We sincerely appreciate your support.

LOVE!!!

I generally hate flossing, but the Slate Flosser is honestly amazing. I can’t go more than 12 hrs without wanting to floss and get that clean feeling — it’s addicting!! And my gingivitis is gone, my dentist is amazed! Seriously, worth every penny - my teeth look and feel great and I no longer have to shoot myself in the face with water (waterpik lol).

We couldn't agree more! Who would have thought we'd actually WANT to floss more than once a day, right?! We're so glad Slate has made such a positive impact for you. Keep up the great work!
