Feno Smartbrush Electric Toothbrush
A U-shaped mouthpiece that cups every tooth at once, a 20 second full-mouth cycle, and an AI oral scanner that scores your smile in the Feno app. Foam toothpaste included.
Your bundle saving is active
You did not need a fancier stick. You needed a smarter tool.
Two minutes twice a day is the official advice, and most of us do it anyway. But a manual or spinning-head brush only ever touches one or two teeth at a time, and it depends entirely on your wrist, your angle, and your patience at half seven on a Monday. The back molars get the least attention. The gumline gets the wrong pressure. And the daily habit that was supposed to protect you slowly starts working against you.
The Feno Smartbrush skips that whole tradeoff. A soft U-shaped mouthpiece hugs every tooth at the same time. 18,000 ultra-soft bristles do the moving. You just hold it in place, look in the mirror, and let 20 seconds do what four minutes used to almost manage.
Six things this brush does that yours does not.
TrueFit Mouthpiece
A personalised U-shape scanned to your teeth so bristles reach every surface evenly, top and bottom.
18,000 ultra-soft bristles
Delivering 250+ strokes per 20 second cycle. Gentle on gums, thorough on plaque.
AI oral scanner
An on-device camera takes a scan and the app returns a clear oral health score you can actually track.
Feno app insights
Weekly scores for teeth, gums, tongue, and soft tissue. A visual streak tracker keeps the routine honest.
One month battery
A full charge lasts around 30 days of daily use. Ready when you are, even if the routine goes travelling.
Foam toothpaste included
Xylitol-based foam that fills every corner of the mouthpiece for a fresh, even clean.
All 32 teeth. At the same time. In 20 seconds.
Regular electric brushes clean one tooth at a time and rely on you to move them evenly. The Feno Smartbrush cradles the whole arch at once, so every tooth gets the same soft, oscillating attention, front and back, upper and lower.

Twenty seconds is all it looks like.
Set the mouthpiece, press once, breathe. The Smartbrush handles the pressure, timing, angle, and coverage while you get on with your morning. When it stops, your teeth feel like you have just left a dental hygienist chair.
The device on screen at your bathroom counter looks like a small speaker with a friendly display. It says good morning by name, shows you the timer, and quietly logs your routine to the Feno app.
Not just for you. For every version of your morning.
School run, work call, no time.
Set the mouthpiece, twenty seconds, done. You still have a coffee window before you have to leave.
Gentler than the brush you dread.
Ultra-soft bristles reach around brackets and along the gumline without scrubbing or scraping.
The routine you actually finish.
When you are tired, two minutes with a manual brush becomes forty seconds. Twenty seconds with Feno stays twenty seconds.
Progress you can point to.
The Feno app shows week over week improvements for teeth, gums, tongue, and soft tissue. Data you can actually use.
One brush, one battery, one bag.
A month of charge means you can leave the cable at home for most trips. It is the lightest oral care kit you have ever packed.
One Smartbrush, personalised per person.
Each user gets their own TrueFit mouthpiece and profile in the app, so the score you see is genuinely yours.

Everything you were about to ask.
Is it actually safe for daily use and for sensitive gums?
Yes. The Feno Smartbrush uses 18,000 ultra-soft bristles inside a soft silicone mouthpiece, so there is no scrubbing pressure like a standard electric or manual brush. The 20 second cycle uses gentle oscillation rather than aggressive spinning, which many users describe as noticeably kinder to their gumline. Replace the mouthpiece every three months, or sooner if bristles look worn, for best results.
Does it really clean my whole mouth in 20 seconds?
The mouthpiece hugs every tooth at the same time, so all 32 surfaces are being cleaned simultaneously. A standard brush cleans one or two teeth at a time and asks you to move it around for two minutes. Here, the coverage is happening in parallel rather than in sequence, which is why 20 seconds is enough to feel a full clean.
Can I use it with braces, crowns, or dental work?
Many users with braces and other dental work find the soft mouthpiece easier and gentler than manual brushing around brackets and wires. Because the TrueFit mouthpiece is scanned to your teeth, it fits your actual anatomy rather than a generic shape. As always, if you have recent implants, surgery, or specific dental concerns, check with your dentist before switching your routine.
What is included in the Starter Kit?
The Starter Kit ships with the Feno Smartbrush device, a TrueFit mouthpiece, and the Feno foam toothpaste. Once paired to the app, you scan your mouth and receive your personalised mouthpiece so your daily routine is tailored to you.
How long does the battery last?
Roughly one month on a single charge with daily use. That means you can leave the cable at home for most weekend trips and even a full holiday, and only think about charging it about once a month.
How is it delivered and what if I need help?
Every order ships with tracked delivery to your door and secure checkout. Our support team is available for 30-day support if you have any setup questions or want help getting the most out of the Feno app.
