Slate Pro 3-in-1 Rechargeable Electric Flosser, Dentist Invented

I’m a registered dental hygienist, and I actually received one of these from a dental sales rep. My first reaction was, “I’ll never recommend this to my patients.” I couldn’t have been more wrong. After using it myself, I was genuinely impressed. I’m a huge advocate for string floss, but the Slate Pro has earned a place in my recommendations because it removes one of the biggest barriers to flossing: ease of use. The long handle makes it incredibly easy to reach the back molars an area many people struggle to clean effectively which will give them inflamed gums annd cavities and the ergonomic design makes daily flossing much less of a chore. No home device replaces a professional dental cleaning, but pairing this with a quality electric toothbrush gets patients much closer to maintaining a truly clean and healthier mouth between hygiene visits. I’ve also found it’s ideal for travel since it’s compact, easy to pack, and doesn’t require the extra accessories that many other oral hygiene devices do. The biggest reason I recommend it is compliance. The best oral hygiene product is the one people will actually use consistently. I’ve had patients switch to the Slate Pro because they found it easier than string floss, and when they use it daily, I often see less plaque and tartar accumulation, healthier gums, and improved periodontal measurements at their recall appointments. I went from being completely skeptical to recommending it with confidence, and buying it for friends and family members as a gift. That’s about the highest compliment I can give any dental product.

This flosser has made flossing so easy for me. Prior to ordering it I struggled to floss as often as recommended by a dentist but this has made the floss routine quick and easy. It removes food particles missed by brushing alone so efficiently even if you miss a day or two. The only thing that took some adjusting to was the intensity of the vibrations even at the lowest setting but after a few uses it was fine (but have yet to use past the lowest setting). The rubber gum bristles are a huge win as they help protect gums from rubbing against the hard plastic. The tongue scraper is durable enough but still comfortable and not too abrasive.

I must admit, I initially approached the Slate Flosser with a degree of skepticism, suspecting it might be more of a novelty than a meaningful addition to my dental routine. However, after noticing similar products gaining traction and receiving a thoughtful recommendation from my dental hygienist—who praised its design and concept—I decided to proceed, especially knowing it was developed by a dentist. Now, after three weeks of consistent nightly use, I can say without hesitation that this device has far exceeded my expectations. My teeth feel remarkably cleaner, and I’ve come to genuinely enjoy incorporating it into my daily regimen. The flosser offers three speed settings, with the medium speed striking the ideal balance for my needs. Initially, I harbored concerns about the durability of the floss heads, fearing they might wear out within days. I’m pleased to report that they’ve proven impressively long-lasting. I’ve since enrolled in a subscription to receive replacement heads approximately every 20 weeks—a convenient and worthwhile arrangement. Though my first interactions with customer service were met with modest delays, once I connected with Toni from their team, communication became prompt and helpful. I also found that while the learning curve took a couple of days, the device soon became intuitive and effortless to use. Notably, after three weeks of regular use, I have yet to recharge the unit—a testament to its excellent battery life. In sum, I wholeheartedly recommend the Slate Flosser to anyone seeking a cleaner, more satisfying oral care experience. It is an outstanding product that truly delivers.

After two weeks of daily use, I can say that I am pleasantly happy with this purchase. This is an excellent electronic flosser. It's well designed and works. I studied the videos on the proper technique, hold at the grip pad, and sometimes even place a little bit of gum oil on the floss and that helps to make the floss last a little longer. I clean the flosser daily. I have tight contacts so it doesn't last me a full week so far but I am working on learning how to use the flosser more effectively. I may need to purchase the thin floss heads listed on their webpage. I tried the competitor Flaus electronic flosser and returned it shortly after purchasing because it didn't work for me. The flaus floss heads snapped, had slack, and broke way too easily. The Slate Flosser is the superior product in my opinion and hands down is the better design. I appreciate the different floss head options and the rechargeable design. My only feedback is, I reached out with a question via email and didn't receive a response and I wish that they sold the tight contact floss heads on Amazon. They do sell their other floss heads on Amazon Prime.

Pros: Super easy to use Powerful yet gentle clean Reaches areas traditional floss can’t Long battery life Quiet Cons: Slight learning curve A bit pricier than string floss—but worth it Compared to traditional floss, this is in a different league—it’s faster, more effective, and way less hassle. The battery lasts a long time between charges, and the overall performance is consistently great. The build quality is solid, the device is quiet and it's fairly portable. If you're tired of flossing being a chore (or skipping it altogether), this device will change that. I was surprised how easy it was to get between teeth, especially those hard-to-reach spots in the back. Bottom line: It’s a bit of an investment upfront, but if you care about your teeth, it’s totally worth it.

This is my review of a Slate Flosser I purchased, not based on a free product. This is a fantastic product, well designed, nicely packaged and convenient. Instructions are clear, the device comes with sufficient charge for several uses before needed to recharge. The proprietary charging cable has a strong magnet to easily connect and charge. The unit is comfortable to grip, vibrations settings are three and it remembers the last used setting. The good: the floss heads have ribbed sides to clean the gums. They are easy to swap, they firmly attach to the flosser. The memory setting prevents having to push the button until the desired power setting is achieved. Battery life is good. Instructions are clear and the unit comes well packaged. The bad: Slate took a page from Apple and ships the product with no power adapter. They recommend at least 20w which is a standard now but for the price it should have included the power adapter. The heads are expensive, seems they want to recover R&D costs as soon as possible, I guess that number of glossers sold versus number of replacement heads sold will give them a comparison point and lower the price. A head that last about a week of less at $30 per box of 20 is hard to justify for 450 strings that go between your teeth and start breaking immediately. Final impression: I will use it for a while, works great, but will see if pricing for consumables go down, I hope. I don’t think we will see knockoff heads any time soon.

I have several crowns and the flosser was able to move around most of my crowns, but it got snagged on one crown. I had to cut the flosser floss to remove it from between my teeth. This crown is about 6 months old. So, this problem could be a “me” problem. But I can’t use the flosser.

My teeth feel smoother and cleaner than ever; Flossing is faster, more efficient and oh so thorough! It took me at first several nightly flossing sessions to get the feel, to first slide floss down between tightly spaced teeth easily (forcing can break floss) and then curve around each side of each tooth - as clumsy as learning the piano, at first. Now flossing is a breeze and a pleasure! The power of sonic vibration to break up plaque forming bacteria vs flossing by hand is the magic. And easy care: I add a drop of soap to the floss head & handle, rub it all around, rinse, wipe down, let air dry. Change floss head weekly. Battery lasts a couple months. So very glad I found this flosser. Game changer on a nightly and essential hygiene task.

The ease of use and convenience makes me adhere to regular daily usage. I would like to come back later for an update after the dentist cleaning visit feedback.

I cannot recommend these highly enough! My teeth feels so clean and smooth.

I would not recommend this product for people who generally use dental tape due to teeth being close together. I thought the hi frequency vibration would help make the floss go easily between teeth but that is not the case. I only used it once and unfortunately it was too late to return it.
