Flaus is an electric flosser that helps improve gum health and build a consistent daily flossing habit. Features include an ergonomic, waterproof (IPX7) handle, a rechargeable battery that lasts 2 months, and recyclable refill heads that significantly reduce plastic waste compared to traditional floss. The combination of high-frequency vibrations and strong, thin glide floss allows the Flaus Electric Flosser to move gently and effectively between even the tightest teeth.
What is the Flaus electric flosser and how does it work?
The Flaus electric flosser is a handheld oral care device that automates flossing. It uses up to 18,000 sonic vibrations per minute to move a disposable floss head back and forth, disrupting plaque and debris between teeth and along the gumline without requiring users to put their fingers in their mouths.
The Flaus electric flosser was created to solve a simple problem: traditional flossing can be difficult, which is why so few people do it consistently. This oral-care device transforms flossing from a manual, technique-sensitive chore into a simple, guided ritual, much like the electric toothbrush did for brushing.
The patent-pending device uses high-frequency sonic vibrations to create a rapid side-to-side scrubbing motion. This "floss-assist" motion, paired with high-quality dental floss on the replaceable refill heads, mechanically removes plaque biofilm.
Plaque is the sticky film of bacteria that constantly forms on teeth and is the primary cause of cavities and gum disease. By automating the most challenging part of the flossing technique, Flaus makes it easier to clean effectively and build a healthy daily habit.
A key benefit is the "finger-free" design, which improves hygiene by keeping the millions of bacteria from your hands out of your mouth. This also makes Flaus an excellent solution for people with dexterity challenges, arthritis, or anyone who simply finds wrapping floss around their fingers uncomfortable.
Which features of the Flaus electric flosser matter most?

The most important features of the Flaus electric flosser are its powerful sonic vibrations (up to 18,000/min) for effective cleaning, a thoughtfully designed refill head with strong-glide floss for tight teeth, a rechargeable battery with a 2-month runtime, and a fully waterproof (IPX7) ergonomic handle for convenience and control.
Speed & Vibration: The device offers three speed settings, reaching a maximum of 18,000 sonic vibrations per minute. This high frequency does more than just clean quickly; the vibrations help gently "saw" the floss through tight contacts between teeth, reducing the need for force. The motion also provides a gentle massage to the gums, which can help improve circulation and gum health.
Refill Head Design: Flaus refill heads use a high-performing PolyTetraFluoroEthylene (PTFE) monofilament tape floss. This material is PFA- and PFO-free, exceptionally thin, and resistant to shredding, making it ideal for navigating tight teeth. The floss is intentionally designed with some slack, allowing you to create the dentist-recommended "C-shape" by wrapping it around the tooth surface for a more comprehensive clean below the gumline.
Battery & Charging: A single charge from the included USB charging base powers the Flaus electric flosser for up to two months of daily use. This long battery life adds convenience and eliminates the environmental waste and recurring cost associated with disposable batteries.
Waterproof Rating (IPX7): The device has an IPX7 waterproof rating, meaning it can be safely submerged in up to 1 meter of water for 30 minutes. This practical feature allows you to use Flaus in the shower, making it even easier to incorporate into your daily routine.
Ergonomics & Noise: The Flaus device features a premium, soft-touch handle that is ergonomically designed to feel as familiar as an electric toothbrush. This design provides superior control and comfort, especially when reaching back molars. The device also features a quieter motor for a more pleasant user experience.
What comes in the Flaus Starter Kit, and how do refills work?
The Flaus Starter Kit includes the Flaus electric flosser device, a charging base with a USB cable, and an initial supply of 45 Flaus refill heads. Refills are available through a convenient subscription service that automatically delivers new heads, which can be easily paused or rescheduled at any time.
Inside the box, you will find everything you need to get started on your new oral care ritual:
1 Flaus Electric Flosser
1 Charging Base
1 USB Cable
45 Flaus refill heads
The refill subscription is designed for convenience, ensuring you never run out of fresh floss heads. When using one head per day as recommended, the subscription costs about $5 per month, which is comparable to the price of traditional floss at a drugstore. You can manage your subscription through your account, giving you full control to pause, reschedule, or cancel as needed.
Is the Flaus electric flosser recommended by dentists?

Yes, the Flaus electric flosser is designed with input from dental experts and is recommended by dentists. The clinical rationale is based on the established effectiveness of mechanical interdental cleaning for removing plaque and reducing gingivitis, which is supported by research from leading dental authorities.
Flaus was "designed with dental experts from day one" to ensure a safe, superior clean. As Dr. Vivian Roknian, DMD, states, "Flossing is critical to maintaining good oral hygiene. Flaus makes flossing easy, cleans great, and is gentle on gums... I am picky about what I personally use and recommend for my patients - and I love Flaus!"
The science behind this recommendation is straightforward. The goal of flossing is to mechanically disrupt the plaque biofilm in areas a toothbrush cannot reach. If this plaque is not removed, it leads to gingivitis (gum inflammation), which can progress to more serious periodontal disease.
A landmark 2019 Cochrane Review, which analyzed the highest-quality evidence available, concluded that interdental cleaning plus toothbrushing may reduce gingivitis and plaque more than toothbrushing alone. Flaus provides a modern, user-friendly way to perform this essential cleaning task.
Furthermore, recent studies focusing on sonic-powered flossing devices have shown their effectiveness. A 2023 clinical trial published in the International Journal of Dental Hygiene found that a sonic-flosser toothbrush was "statistically and clinically more effective at improving gingival health and reducing plaque than manual toothbrush and dental floss" over a four-week period.
Is an electric flosser better than a water flosser for plaque removal?
An electric flosser, like Flaus, and a water flosser (oral irrigator) clean in fundamentally different ways. An electric flosser uses the physical contact of dental floss to scrape away sticky plaque. In contrast, a water flosser uses a pressurized stream of water to flush away debris and disrupt bacteria. While both can reduce gingivitis, many dentists believe mechanical scraping is necessary to fully remove adherent plaque biofilm.
The key difference is the cleaning method. The Flaus electric flosser provides mechanical removal, using actual floss to physically scrape plaque off the tooth surface. Think of it like scrubbing a sticky spot off a dish. A water flosser provides hydrokinetic disruption, using a powerful water jet to flush away loose particles. This is more like pressure-washing the dish.
While some studies show that water flossers can be as effective as string floss at removing plaque after a single use, the consensus among many dental professionals is that the physical scraping action is superior for removing the most stubborn, sticky layers of biofilm.
The American Dental Association (ADA) notes that water flossing can be a good option for people who have trouble with hand flossing, but it is often viewed as an addition to, not a replacement for, traditional flossing.
Ultimately, an electric flosser provides the proven benefit of mechanical cleaning in an easier-to-use format. In contrast, a water flosser excels at cleaning around braces and implants, and it's especially effective for those with gum sensitivity.

Is the Flaus electric flosser travel-friendly?
Yes, the Flaus electric flosser is designed for travel. Its rechargeable battery lasts up to 2 months on a single charge, and it features a convenient travel lock mode to prevent accidental activation in your bag. The compact device is fully compliant with carry-on regulations.
The extended two-month battery life means you can leave the charging base at home for most vacations or business trips. To prevent the device from turning on inside your luggage, Flaus includes a smart travel lock. You can activate or deactivate this mode by pressing and holding the power button for 5-8 seconds until the indicator blinks. This thoughtful feature, combined with its compact and lightweight design, makes Flaus an ideal travel companion for maintaining your oral care routine on the go.
How do Flaus refill heads reduce plastic waste?
Flaus refill heads help reduce plastic waste by using 95% less floss material than traditional string flossing and 30% less plastic than single-use floss picks. By replacing a year's worth of disposable floss containers and excess string with small, recyclable heads, a single Flaus user can significantly lower their annual plastic footprint from oral care.
To understand the impact, consider the math:
Assumptions:
The ADA recommends using about 18 inches of floss per day.
Over a year, this amounts to 182.5 yards of floss.
A standard floss container holds 55 yards of floss, and its plastic dispenser weighs approximately 16 grams.
The Calculation:
Traditional Floss Waste: A daily flosser would use about 3.3 plastic containers per year (182.5 ÷ 55). This results in approximately 53 grams of plastic container waste annually, not including the floss string itself.
Flaus System: With Flaus, the waste from these bulky plastic dispensers is completely eliminated. The only disposable component is the small refill head.
The Result: By switching to Flaus, you prevent the equivalent of over 3 large plastic floss dispensers from entering the landfill each year. To further this commitment to sustainability, Flaus offers a mail-back recycling program that allows you to send used heads to a dedicated oral care recycling facility for proper processing.

FAQs
How often should I change the Flaus refill head?
For optimal hygiene and performance, we recommend using a fresh Flaus refill head for each flossing session, once per day.
Can I use Flaus if I have crowns, veneers, or braces?
Flaus is generally safe for crowns and veneers, but it's always best to consult your dentist first. While some users have success with braces, a specially designed Flaus head for orthodontics is currently in development.
