Why Twenty Seconds Beats Two Minutes

The two-minute brush was never two minutes.

Studies watch what happens in real bathrooms. Most people finish in under 45 seconds. Bristles skip the back of the molars, the tongue-side of the front teeth, and the gumline where plaque hides. The result is a mouth that feels clean and a checkup that says otherwise.

The Feno Smartbrush Electric Toothbrush changes the math. A soft U-shaped mouthpiece hugs every tooth at once. The brush oscillates 250-plus times in twenty seconds, tuned by onboard AI so gums stay calm and plaque comes off. You get the full clean before the coffee has finished brewing.

The Fitkit Routine

From box to a dentist-clean mouth in four steps.

Every mouth is different. The Feno Fitkit personalizes the mouthpiece to your teeth, so the twenty-second clean actually fits.

Step 01

Scan the code

Find the Fitkit code inside your Smartbrush package and tap into the Feno app.

Step 02

Scan your mouth

The app walks you through a guided scan. Ninety seconds. No mold, no impressions.

Step 03

Get your mouthpiece

We ship a personalized U-shaped mouthpiece built to hug your exact teeth and gumline.

Step 04

Brush in twenty

Click in, press start, and let the AI-tuned oscillation do the whole mouth at once.

Inside The Smartbrush

Six real upgrades over the toothbrush in your drawer.

This is not a sonic head bolted to an app. Every part of the Feno Smartbrush was rebuilt around one job: full-mouth clean in the time it takes to answer a text.

01

TrueFit Mouthpiece

Personalized to your bite so bristles reach every surface, including the back molars a manual brush constantly misses.

02

18,000 Soft Bristles

Ultra-soft filaments cover front, back, and top of every tooth at once. Gentle on gums, thorough on plaque.

03

AI Oscillation

Onboard AI tunes 250-plus oscillations per twenty-second cycle. No overpressure, no missed zones.

04

Oral Scanner

An in-device scanner captures your smile after brushing and scores your daily oral health inside the Feno app.

05

30-Day Battery

One charge lasts a full month of daily use. Travel, camp, or move without hunting for the cord.

06

Foam Toothpaste

Xylitol-based foam is included in the Starter Kit. It reaches every corner and leaves a natural, non-minty feel.

A Closer Look

Every part built for a full-mouth clean.

A

Onboard Display

Shows your brushing time, oral health score, and personalized morning reminders.

B

AI Oral Scanner

Twin lenses capture your teeth after each session and feed data to the Feno app.

C

TrueFit Mouthpiece

Custom U-shape wraps every tooth. Swap heads every three months to stay fresh.

D

Wireless Dock

Charges through the base. One plug-in gives you a full month of daily brushing.

Live Demonstration

Watch a twenty-second clean, unedited.

Real routine, real timer, real mouth. This is what a Feno Smartbrush session actually looks like from click-in to smile check.

00:00

Click the mouthpiece in

Foam toothpaste is already on the bristles. Bite gently and press the front button.

00:20

Full-mouth clean, done

Rinse, smile, and let the scanner log your session. Score appears in the Feno app.

Real Mornings, Real Nights

When twenty seconds actually matters.

The Smartbrush earns its place on the counter in the moments when a manual brush usually loses.

Feno app oral health score view

Rushed weekday mornings

Alarm to out-the-door in twenty minutes. Click, twenty seconds, coffee, done. No more skipping the back molars.

Feno Smartbrush charging dock

Business travel weeks

Thirty-day battery means one charge covers the whole trip. Toss it in the case with the mouthpiece and go.

Feno Foam toothpaste bottle

Late-night routines

Foam toothpaste and a soft U-shape mean you can brush thoroughly without waking up your face at midnight.

Lauren McKellar

Twenty-second cycle, tested

A single Smartbrush session takes twenty seconds from start to rinse, with 250-plus AI-tuned oscillations covering every tooth surface. That is roughly six times faster than a standard two-minute manual routine, without cutting coverage.

Cover front, back, and top of every tooth at once.

Answers Before You Buy

Questions, answered honestly.

The Feno Smartbrush uses 18,000 bristles to touch every tooth surface simultaneously. A manual brush covers one or two surfaces at a time, so two minutes are needed to reach roughly the same area. Same coverage, fraction of the time.
Yes. The TrueFit scan personalizes the mouthpiece to your teeth and gumline. Ultra-soft bristles are gentle enough for sensitive gums while still lifting plaque.
One Feno Smartbrush device with its onboard display and AI scanner, a personalized TrueFit mouthpiece, one bottle of Feno Foam xylitol toothpaste, a wireless charging dock, and access to the Feno app.
Around thirty days on a single charge with daily use. Perfect for travel or long weekends where you would rather leave the cord at home.
The Smartbrush cleans just as well on its own. The Feno app adds oral health scoring, brushing streaks, and reminders if you want deeper insight into your routine over time.
Every three months, or when the bristles look worn. Replacement mouthpieces are available in your Feno account whenever you need them.
Every order includes 30-day support directly from the Feno team. Reach out inside the app or by email and a real person will help you fit, adjust, or troubleshoot.
Important notice: This product supports an everyday oral-care routine and is not a substitute for professional dental advice, diagnosis, or treatment. Consult a qualified dental professional about individual concerns or ongoing treatment.
