You too can select your brushing mode and scroll by settings and, when you begin brushing, the display screen will show a timer. Though I initially felt the display screen was an over-the-top add-on, the timer is now’s certainly one of my favorite options. If I’m utilizing one other brush, I’ll instinctively look down for it.
I’ve discovered that it encourages me to brush for longer as nicely, as if I zone out or really feel as if I’ve been brushing endlessly, seeing that I’ve solely obtained 30 seconds left spurs me on to finish it.
There’s a second timer within the type of brush vibrations, which warn you each 30 seconds to maneuver on to the subsequent part of your mouth, and an extended alert once you hit the two-minute dentist-recommended brushing time.

Purchase within the US and the charging puck has a normal two-pin plug. Purchase within the UK and also you’ll get a shaver socket plug. That is true of all Oral-B brushes and it’s my important bugbear with the model. For brushes at this value level, we’d like to see USB charging.
The iO8, like the opposite pricier iO fashions (from iO6 and up), has three-hour quick charging through the magnetic puck. This can be a nice function when in comparison with the usual 12-hour Oral-B cost, though in the event you’re used to quick cellphone charging, it’ll nonetheless appear to be a very long time.
One slight subject right here is that it’s very straightforward to knock the comb off the puck whereas charging, so be sure it’s in a secure, out-of-the-way spot.
Efficiency
- Glorious brushing efficiency
- Six brushing modes
- 2-week max battery life
The massive distinction between iO and conventional Oral-B brushes is that conventional Oral-B brushes oscillate solely, whereas iO brushes oscillate and sonically vibrate.
The distinction is large. The iO brushing efficiency is second to none – and I don’t know anybody who’s tried it who thinks in any other case.
The iO8 has six brushing modes: day by day clear, delicate, whiten, gum care, intense and tremendous delicate. It’s one lower than the iO9 and yet another than the iO7 – precisely as you’d count on. I didn’t discover the variations between the modes as pronounced as another brushes however I believe there’s sufficient selection to discover a mode that’s best for you.
The iO brushing efficiency is second to none
The iO8’s battery will final for a most of two weeks. In observe, I discovered it by no means lasted fairly that lengthy however its clear battery show and quick charging did mitigate that for me.
Sharing
- Not designed for sharing
- App options will likely be restricted
- Brush heads function symbols to distinguish them
The iO8 can be utilized as a shared brush, though it gained’t hold monitor of your particular person brushing file on the app. Oral-B confirmed through a Tweet that though two customers with separate telephones might be capable to use all of the app’s options individually because of the Bluetooth connection (ie so long as the person’s cellphone is inside vary and the opposite’s isn’t), that’s not the way in which the iO was designed.
If multiple individual is utilizing the identical brush, it additionally implies that the comb head alternative reminder within the app gained’t work correctly.
Nonetheless, in the event you’re prepared to forgo a number of the good options, the iO8 can nonetheless be used as a shared brush. It’s straightforward to vary the brushing mode on the deal with in the event you favor completely different modes, and iO heads are marked with small symbols to distinguish them.

Related options and app
- Actual-time brushing suggestions
- Brush head alternative reminders
- Gamification options
The iO8 connects through Bluetooth to the free Oral-B app, obtainable for Apple and Android. In our check, I discovered it straightforward to make use of and fast to attach. The primary purpose to make use of the app is for the interactive brushing suggestions. Watch your cellphone display screen whilst you brush and it’ll monitor the protection as you go.

The iO’s real-time brushing suggestions is about nearly as good because it will get. In my expertise it usually labored nicely, besides I discovered that, with the intention to get an ideal consequence, I used to be brushing for longer than the really helpful two minutes. This impacts battery life and who know – it could be inflicting me to over brush.
One of many causes you’d pay extra for the iO9 and iO10 is their 3D floor AI brushing monitoring however I don’t suppose it’s that significantly better than the real-time assist the iO8 supplies. None of them give good suggestions however in the event you want some construction to get your brushing again on monitor, they could assist.

Other than that, the app permits you to modify brush settings, set brushing targets, go on “dental care journeys” (maybe to enhance your gum well being), see previous brushing efficiency, acquire badges and get reminders to exchange your brush head.
As a lot as manufacturers try to promote us on linked options, most don’t but add sufficient to maintain the typical person coming again. Except you actually need a strict regime of brushing assist, my guess is that you just’ll abandon nearly all of the good options fairly shortly.
Value and availability
The Oral-B iO8’s value level varies relying on the place you’re based mostly.
Within the US, it’s broadly obtainable direct from Oral-B, and from different retailers like Goal and Greatest Purchase for round $249.99.
Within the UK, the iO8 had a launch value of £450, which we thought was wildly overpriced. Nonetheless, throughout common gross sales durations, it might drop to its present value.
On the time of writing, it’s broadly obtainable for £170, from websites together with Boots, Oral-B and Currys. We don’t suppose it is best to pay greater than this. It’s nonetheless not a cut price value however this can be a luxurious merchandise that’s filled with state-of-the-art options and we expect it’s value it.
