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."

Great product!

I love the Slate Flosser and the auto-renew function for the floss heads. I've always been a regular flosser, and I appreciate how easy it is to use the device and to replace the floss heads.

Thank you for this great review, Martha! We're so glad that you're loving your Slate products and that you find the subscription option makes it easier to get floss head refills when you need them!

Sooo smooth

The new grey smooth gloss heads absolutely live up to their name. The difference has been noticeable to me… no more issues of floss getting stuck between my teeth. Highly recommended.

That is amazing news, Clara! We're so glad that the new SMOOTH floss has made a noticeable difference for you already!

Loving it!

I tried a different brand’s version of this and it was awful. A friend raved about Slate so I tried it and I love it! I am disabled and cannot do regular floss so this is really a lifesaver.

We're thrilled to hear that you are loving our Slate Rechargeable Electric Flosser. We pride ourselves on providing high-quality products that make a difference in our customers' lives. We are so glad to know that our flosser is helping make your daily oral care routine easier. Thank you for choosing Slate and for sharing your experience with us!

SO GOOD

I seriously love this flosser. Who knew that an electric flosser could make such a difference. After getting a cavity between two teeth, I knew I had to step up my flossing game. My teeth feel so clean and I actually enjoy flossing now. No more wrapping my fingers. The gum sweeps feel really nice too. If you're worried about only changing the floss head once a week, remember this, you use the same toothbrush for 3 months! Get it! Your teeth and gums will thank you.

Wow, we couldn't have said it better ourselves! Thank you so much for the amazing, detailed testimonial! We're so glad that your Slate Electric Flosser has been such a game-changer for you. Thank you for choosing our product and keep up the great flossing!

Easy easy easy

Flossing is so much easier with this product! Yes, I get excited about not missing any days flossing!! Its been relatively effortless to do and I actually enjoy doing it!

Thank you so much for your wonderful feedback, Dr. Barton! We're so glad that you're enjoying flossing with the Slate Rechargeable Electric Flosser. We get excited about not missing a day of flossing as well! Slate makes the process simple, quick, and easy to make part of your daily routine.

Great

I've been meaning to write a review for the Slate Flosser for a while. It is the best thing I have purchased in a long time. I've always had a hard time with flossing, it hurts my mouth and my hands and I always had to force myself to do it, but I'd still forget frequently. I got one of those long handled flossers, which was an improvement, but I still disliked doing it. I was really excited to try the Slate flosser, but didn't want to get my hopes up. When I got it, though, I liked it immediately. After I learned the "roll and sweep" method (video on site) I enjoyed it even more. This method makes it easier and more comfortable, and also extends the life of the heads. I have never before in my life looked forward to flossing until I got this, and now I do. Seriously, I had to cut down on my flossing because at first I was using it like 4 times a day. :D When I like something, I really like something! I got the smooth heads which get into tight and sharp places and I found this head lasts longer for me. Another thing I love is they really have excellent customer service. I highly recommend the Slate Flosser, it immediately turned me into the regular flosser I always wanted to be! Thank you!

What an incredible testimonial! Thank you, Leigh, for sharing your detailed, thoughtful feedback. We're so happy to hear that the Slate flosser has been a game-changer for your routine and has helped you look forward to flossing! We appreciate you sharing your story with us and we're so thrilled that you have had such a positive experience with Slate products and staff. Keep up the amazing work!

LOVE

I absolutely LOVE this flosser. It's so easy to use, feels nice and keeps my teeth so clean. I loathe wrapping floss around my fingers, this device takes away that dread. It's nice to properly floss, the backs of my lower front teeth still look like I had a cleaning done. Amazing. Instead of dreading flossing, I am truly enjoying it.

Wow, thank you so much for your kind words and for sharing your positive experience with our Slate Rechargeable Electric Flosser! We're excited to hear that it has made flossing a more enjoyable experience for you and has left your teeth feeling clean. We appreciate your support and are happy to have you as a satisfied customer. Keep up the great work flossing with Slate!

Makes it Easier to Floss!

I am unable to open my mouth wide enough to floss due to rash and chapped mouth.. This has been so much more gentle and comfortable with no pain. Customer service is fast and respectful.

Thank you so much for this great personal testimonial! We are so glad to hear that the Slate flosser has made flossing easier and pain-free for you, and that you've had a great experience with our customer service team!

I floss more than ever and enjoy doing it with my Slate flosser!

We're so happy to hear that you're enjoying the Slate Flosser and Emerald THIN Floss Heads and that they're helping you floss more regularly. Keep up the great work!

Obsessed.

The slate flosser is truly one of a kind. You have a customer for life.

That is the best news ever! Thank you so much, we're so glad to welcome you to the Slate family!

My dentist gave me an A+!

I’ve always had a difficult time remembering to use traditional spools of floss on a regular basis. They’re time consuming and frustrating to me. And then I would run out and not get a refill. Then I tried one of the flosser sticks, and I loved it. It helped me get between my tight back teeth and helped me be more efficient. BUT I was creating so much waste AND still had to remember to buy refills.

The Slate flosser has little brushes on the sides of the floss heads to stimulate/clean my gums, the pieces last longer, it’s powered with vibrations for a better clean, and the brush heads are recyclable. Honestly, it’s perfect for me.

Even better: I had a dentist appointment a few weeks after getting it and he told me my teeth looked great! My gums weren’t bleeding, and no cavities!

Amazing product!

I actually enjoy flossing thanks to Slate - I love how easy and thorough the electric vibrations make flossing!

Brooke, thanks for taking the time to share your experience with our Slate Rechargeable Electric Flosser. We designed it with ease and effectiveness in mind, so we are happy to know that it has made a positive impact on your oral hygiene routine. Keep up the great work flossing with Slate! :)

Really enjoy using this. It's simple to use. Flossing isn't a chore anymore. Happy with this purchase.

New Gray SMOOTH Floss Heads

Love it

Haven’t used it very long but easy to use flosser. Only thing I don’t like it’s how bright the charging light is, it’s like a night light.

Hi Rachel,

Thank you so much for your thoughtful review and feedback! We just wanted to make sure that you know that you do not need to charge the flosser until the battery indicator light flashes RED. Most customers are able to use the flosser for 1-3 months (with daily use) on a single charge! This actually can help preserve the battery life, too. Feel free to reach out to our customer support team if you have any questions!

Gray Smooth

The new Gray Smooth Floss Heads are a game changer. With all the other heads it was hard to make myself use the flosser everyday. With the Smooth floss heads it's so much easier because my teeth are close together.

Thank you so much for this wonderful feedback on our new SMOOTH floss heads, William! We're so thrilled that they're a great solution for your tight contacts. Keep up the great work flossing with Slate!

Makes flossing easier with my big mits

I have been using the Slate Flosser for about a week now and beginning to like how I can get everywhere, even between tight back molars, and get a more thorough flossing with my large hands.

We're so glad to hear that! It's great to know that you're able to reach those tight back molars easily and avoid having to get your hands in your mouth to do so! Keep up the great work flossing with Slate!

I LOVE my slate flosser! I thought it would hurt the inside of my mouth, but it really doesnt. Using the slate with these flosser heads, makes me feel like I’m really taking good care of my teeth.

Love it

My dentist was shocked I had no build up at my teeth cleaning visit when I started to use slate. My gums were so great he was shocked I had no issues as well. This product works extremely well!

Kirsten, thank you for sharing your amazing results! We're so glad that the Slate flosser has made such a difference for you. Keep up the great work with your oral care routine!

Amazing product! Best in class

Game Changing Flosser

I had a dentist appointment this morning and the hygienist said "I barely had anything to clean. Whatever you're doing is working well, so keep it up!" The only change has been the addition of the flosser, I am very happy with that feedback. The flosser is so easy to use and integrate into your daily routine, there is no excuse to not floss regularly.

Thank you for your stellar review, Logan! We are thrilled to hear that our Slate Rechargeable Electric Flosser has made such a positive impact on your oral health, and that your hygienist noticed a difference at your appointment. We're so glad it's making flossing a regular habit for you. Keep up the good work and thank you for choosing Slate!

So easy!

Its just so easy to use and both massages the gum and cleans and does so well - Love it!

Thank you for your kind words! We're glad to hear that our Slate Rechargeable Electric Flosser has been easy to use and effective for you!
