Best Prices Today: Oral-B iO Series 7

$151.33

Oral-B has so full a range of electric toothbrushes that deciding which one is for you would confuse even a dentist. At the last count, Oral-B has nearly 20 different brushes to choose from.

The advanced iO series, with a cleaning system powered by a quieter brushless motor, are the best models in the Oral-B line-up, but even then there are—depending on where in the world you are based—eight different models to choose from: starting at the budget iO Series 3 and ending with the top-end super-expensive Series 10.

All of the iO Series handles share many of the same features, including both oscillation and sonic “micro vibrations” as part of the cleaning process.

All have a two-minute timer to ensure you brush for the recommended time, pacer, smart pressure sensor to protect your gum line from over-brushing, and decent battery life.

Indeed, the basic cleaning action is the same irrespective of the iO model that you purchase.

The differences are largely the number of brushing modes offered by each model: the Oral-B iO3 has three, Oral-B iO4 has four, Oral-B iO5, Oral-B iO6 and iO7 have five (although not the same modes), the Oral-B iO8 has six, and the Oral-B iO9 and Oral-B iO10 both have seven.

If you are going to use only the basic Daily Clean mode, then you can safely ignore all the extra modes, but the later Series iO models do have a few other features to stop everyone choosing the cheapest Series 3, such as smart features and an integrated screen to display brush mode, duration, charging speed and battery life.

You can check out the pros and cons of each of the Oral-B iO Series toothbrushes in our Oral-B electric toothbrush comparison feature.

Our Best Value iO Series Oral-B electric toothbrush is the iO Series 6. Our Best Luxury model is the iO Series 8.

So what of the iO Series 7—could this be the sweet spot between affordability and premium features?

Design

• Black-&-white screen to show timer and battery life
•  3-hour fast charge
•  Light ring pressure sensor

The iO7 is the entry-level of the high-end iO models, fourth to the 1O8, iO9 and the iO10. I has all the key features of the top models, including three-hour fast charging and a full-colour OLED screen.

The iO7 has a monochrome display, compared to the iO8/9/10’s color OLED display. A color display looks nicer but doesn’t convey any new information than the b&w one. I wouldn’t pay the extra money just to have a color display on my toothbrush.

The screen gives you a little welcome icon—either sunshine, winky or a smiley face and a hello.

Once you start brushing, the screen displays the timer, showing you a ring that fills each quarter every 30 seconds—indicating time to move on to a new section of your mouth.

I found this display quite difficult to see during brushing, and mainly relied on the haptic vibration every 30 seconds.

However, it can be easy to miss these if your thoughts drift off to other matters, as can be common when performing a mundane task first thing in the morning or last thing at night.

The display comes into its own here. I found it easiest to check by looking at its reflection in the mirror rather than turn it round and look at the brush itself, spraying my face as a result.

The screen also shows you the remaining battery life—in increments of 5%—each time you finish brushing.

You can also open up the app and using the brushing feedback timer there.

You can personalise your iO7 brush by choosing from one of ten bright colors for the light ring around the brush’s neck. The light ring glows in your chosen color as soon as you begin brushing.

It switches to green when you assert the ideal amount of pressure. If you press too hard, the neck ring will glow red.

These are simple and effective ways to give you visual feedback on your brushing technique.

The iO7 comes in three handle color options: Black Onyx, White Alabaster, and Blue Electric; although finding the blue model outside of the US is not as easy as the other two basic colors.

In the iO7 box there’s a fast-charging magnetic charging puck, a robust travel case, the brush handle and two brush heads. The case is useful for keeping your expensive brush safe, and it also stops the brush going off in your suitcase if accidentally bumped in transit—I once arrived at my destination only to hear a deep vibrating noise emanating from my baggage on the carousel, resulting in a dead battery when I most needed a brushing session after a long-haul flight.

Tech Advisor’s toothbrush aficionado, Emma Rowley, reckons that the Oral-B travel case is not as sharply designed as the one that comes with the Sonicare DiamondClean 9000.

The iO9 and iO10 come with a power2go charging case that can charge the brush inside, compared to the iO7 and iO8’s non-charging case-only option.

Performance

• Excellent brushing performance
• Five brushing modes
• Two-week max battery life

Of course, the most important factor to consider when choosing an electric toothbrush is its cleaning performance.

While traditional Oral-B brushes oscillate only, the iO brushes both oscillate and sonically vibrate, removing plaque even more efficiently.

This dual-action cleaning works wonders, and my hygienist complimented me on the difference once I’d moved to the iO brush.

It can feel a little harsh at first, but you soon get used to the brushing and your teeth feel great after the regulation two minutes.

If you find the Daily Clean to be too light, try out the tooth-rattling Intense mode. My daughter immediately set hers to Sensitive.

Oral-B

Brush modes

The on-brush display is where you can see which brush mode you have selected. The default brush mode is Daily Clean, and is likely the main—maybe only—mode you use.

The iO7 has five cleaning modes: Daily Clean, Sensitive, Intense, Whiten & Gum Care. This compares to the six of the iO8: Daily Clean, Sensitive, Super Sensitive, Intense, Whiten & Gum Care.

What is Super Sensitive and do you need it? If your teeth are extremely sensitive, then you should consider the iO8 over the iO7. But most users, as expressed before, will likely stick to Daily Clean only, so could save money and buy the better-value iO6, although the charging time is considerably longer (12 hours rather than the iO7’s three).

If you want the 30-second Tongue Clean mode, you’ll need to consider the iO9 or iO10.

Oral-B

Charging

The cheaper iO6 can take up to 12 hours to charge its lithium-ion battery, so that’s the first benefit the iO7 has over the iO6. That model uses the standard charger with the pillar in the middle. The iO7, like the 8, 9 and 10, uses a newer magnetic charger in either white or black.

The iO7’s battery should last for two weeks. In practice, I found it lasted around 10-11 days. To be fair, I often brush for longer than two minutes as I like to focus on cleaning my gums as much as my teeth.

Buy in the US and Oral-B’s charging puck has a standard two-pin plug. Buy in the UK, however, and you’ll get a shaver socket plug.

In my (UK) bathroom, this can be a hit-or-miss affair when charging as I often need to keep the shaving plug pushed to one side to operate. To be fair, this is likely just a wiring fault in my home, but I ended up buying the same charger with a standard UK plug and charged out of the bathroom. (If any reader shares this problem, I’d love to hear from you.)

A simple solution would be to offer USB charging of the brush, although I understand the old-school bathroom/shaving socket thinking.

Oral-B iO7 vs Oral-B iO8

The simple differences between the Oral-B iO7 and iO8 are the iO8’s color display and extra Super Sensitive brushing mode.

if you don’t need a Super Sensitive brush mode—the iO7 does has a Sensitive mode—the color screen isn’t worth the extra cost of the iO8. It’s nice but in no way essential.

There’s no difference in brushing performance, charging speed or accessories between iO7 and iO8. As such, we recommend the cheaper Oral-B iO7 over the iO8.

Sharing

• Not designed for sharing
• App features will be limited
• Brush heads feature symbols to differentiate them

With the top-end iO brushes priced at a premium, the idea of sharing the same handle but swapping out the brushes for each individual is economically appealing.

The iO7 can be used as a shared brush, although you’ll lose some of the smart features in the app as it won’t keep track of your individual brushing records.

If you do share the same brush, the brush head replacement reminders in the app won’t work properly.

Some retailers sell a value-pack box that includes two handles, but only one charger and case. As most families will likely share a charger, this way of saving on costs is appreciated.

You can always buy another charger or travel case separately if you decide you need two of everything.

Connected features and app

• Real-time brushing feedback
• Brush head replacement reminders
• Gamification features

The iO7 connects via Bluetooth to the free Oral-B mobile app, available for iOS and Android. The app offers interactive real-time brushing feedback. Note, though, that you have to watch your phone screen while you brush if you want to track the coverage as you go.

While this works well, I suspect that most users will prefer to just brush their teeth without having to stare at their phone—although some people will jump at any chance to stare at a phone at any time of the day!

You don’t need to open the app to use the toothbrush, and most users won’t bother, although you’ll learn more about your brushing skills if you use it at least to begin with.

The more expensive iO9 and iO10 offer 3D surface AI brushing tracking if you really need to get the fullest representation of your brushing performance and technique. Those models monitor 16 zones rather than the six of the iO7.

You can also use the app to adjust brush settings, set brushing goals, go on “dental care journeys”, see past brushing performance, collect badges and get reminders to replace your brush head.

Price

The Oral-B iO7’s price point varies wildly depending on where you’re based.

In the US, it’s widely available direct from Oral-B, and from other retailers such as Amazon, Target and Best Buy for around $219.99.

In the UK, the iO7 has a ridiculous RRP of £454, which is certainly well overpriced. However, in reality you’ll find the iO7 much cheaper at various retailers, such as Amazon, Boots and Currys, and even at Oral-B’s own online shop—at the time of writing it was on sale for £150 at those retailers, without refills.

That’s still expensive but remember how much a trip to the dentist costs and the initial outlay fades into insignificance. Use this toothbrush correctly, and those trips to the dentist should be rarer and cheaper than if you use a manual or much-cheaper electric toothbrush.

As mentioned earlier, look out for dual packs that offer two brushes but just one charger. These can make buying multiple brushes much more viable. Oral-B UK is selling the two-pack (one black, one white) for £235, at the time of writing, instead of the ludicrous £560 list price. That’s just £117.50 per iO7 toothbrush.

As the magnetic charger will likely differ from the old traditional pronged charger, a family will find it more convenient to all be able to use the same charger—although clearly this significantly increases the outlay.

Remember that to keep it effective, a brush head should be replaced every three months, as after this time it tends to become less effective.

The iO brushes require specific brush heads that cost $17 / £15 each. When you buy the brush, check how many heads are included as some packs included…
