Pro Electric Flosser | Dentist-Invented 3-in-1 Rechargeable Flosser with Reusable Floss Heads, Gum Brushes & Tongue Scraper for a Complete Clean, Up to 14,000 Sonic Vibrations, PFAS/PTFE-Free

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.

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.

This is my second Slate electric flosser because it works. It’s easy to get between my teeth, and my dentist has noticed an improvement in my gums since I started using it. It vibrates sonically, so I just place it between my teeth, move it from front to back a few times, and let the gum massager do its job. It takes me about 30 seconds to do my whole mouth. I originally thought the floss wore down quickly, but after comparing an old head with a new one, they’re about the same. The floss does compress into a thinner, very strong string after the first use, but it still seems to clean well. The refills are on the expensive side, and I usually replace one about once a week. The battery life is excellent. I only need to charge it once every couple of months, which is impressive given how often I use it. Pro tip: When changing the head, clean the flosser itself to keep it sanitary and working its best.

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.

Amazing product!! I love to floss and was excited to try this product. I’ve been using my electric flosser for a little while now, and overall I’m really impressed. It definitely makes flossing easier and quicker than using traditional string floss. I feel like my teeth and gums get a much more clean, and I’ve noticed less bleeding over time, which tells me my gum health is improving. The device itself is comfortable to hold and has different pressure settings, which is nice if your gums are sensitive. The battery life is strong, I can go days without recharging and it’s much quieter than I expected. I highly recommend this product.

An otherwise excellent product that has one clear oversight. The floss is tough enough for me to last at least one week but usually two. I only have a few very tight spaces up front which can be tricky but instead of forcing it you can simply roll it back and forth and it will slide in. The gum sweeps make it easy to perform the suggested 'c-shape' cleaning. The power settings allow you to find a comfortable but effective pulsation. The charging port however is poorly designed for a device that is repeatedly exposed to water. Please update the device to use an induction type charger like the sonic brush then is 5 stars. Mine is corroded now and will not charge. I think I can fix it with a small wire brush and maybe citric acid but that's TBD. If you purchase it, dry it first completely and keep the charger away from water!

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.
