Oral-B has spent decades as the toothbrush dentists reach for first, and the iO line is where that reputation meets genuine smart-home-style technology. Instead of just spinning faster or buzzing harder, iO brushes use a 360° pressure sensor and, on higher models, real-time coaching to help people brush more evenly and more gently at the same time.
What sets iO apart from most “smart” toothbrushes is that the technology actually changes the brushing experience rather than just logging it. The round, oscillating-rotating head combined with Oral-B’s linear magnetic drive produces a distinctly smooth, almost massaging sensation, and the lineup now spans ten numbered models, so features that once lived only on a flagship brush have trickled down to far more affordable options. Shoppers can browse the full range at oralb.com.
Who is Oral-B?
Oral-B has been a fixture in dental offices and bathroom cabinets for generations, and it’s been part of Procter & Gamble’s oral care portfolio since 2005. The brand built its reputation on oscillating-rotating brush technology, and the iO series represents its biggest leap forward yet, adding a magnetic drive system, a 360° pressure sensor, and connected coaching to that core mechanical advantage.

The iO catalog today runs from the iO2 up through the iO10, with each step up the lineup adding more brushing modes, a sharper interactive display, and additional smart features. That range means the technology Oral-B is best known for isn’t locked behind a single expensive flagship; it’s accessible at multiple price points, which is part of why iO has become one of the most recommended electric toothbrush families among dental professionals.
Oral-B also backs the iO line with a broad accessory ecosystem, including specialized brush heads for whitening, sensitive gums and orthodontic care, so one handle can be adapted to a household’s changing needs rather than replaced outright. That flexibility has helped iO remain Oral-B’s flagship technology even as the company continues to refine the lineup each year.
What Oral-B iO does best
A 360° pressure sensor on every model
Even the most affordable iO models include visible pressure feedback, so users can see immediately if they’re brushing too hard, a simple feature that protects gums over the long run.
Multiple brushing modes for different needs
Higher-tier models add modes like Gum Care, Sensitive, Whiten, Intense and Tongue Clean, letting one brush adapt to different routines rather than forcing a one-size-fits-all clean.
An interactive display that actually helps
The color display and two-minute timer keep brushing sessions on track, while connected models relay real-time feedback to the Oral-B app for longer-term coaching.
A noticeably smooth, thorough feel
Oral-B’s magnetic drive technology produces a gentler, more consistent motion than older oscillating brushes, something returning Oral-B users frequently notice right away.
Fast, convenient charging
Premium iO models include a magnetic charger capable of a full charge in around three hours, plus a compact travel case for life on the go.

What customers say
Longtime manual-brush users switching to iO often describe the difference as immediately noticeable, pointing to how clean their teeth feel even on the first use. The pressure sensor draws particular praise, since many people don’t realize how hard they’ve been brushing until the light ring gives them a gentle warning.
Buyers of the connected models also highlight the Oral-B app as genuinely useful rather than gimmicky, with coaching that helps build a more consistent two-minute habit. Across the lineup, the interactive display and smooth magnetic motion come up again and again as the features people notice most once they’ve made the switch.
Who Oral-B iO is best for
Oral-B iO suits anyone who wants dentist-grade technology without committing to the most expensive model on the shelf, since even the entry iO2 includes the pressure sensor and display that define the series. Shoppers upgrading from an older electric toothbrush tend to notice the biggest jump, particularly in how much smoother the brushing motion feels.
Households that want app-based coaching, multiple brushing modes, or sensitive-gum settings should look to the iO6 and above, while anyone chasing the full feature set, fastest charging, and most brushing modes will get the most out of the iO9 or iO10.
Price and value
With entry models starting under $50 and the flagship iO10 sitting around $399.99, Oral-B has built a genuinely wide ladder, which makes it easy to find an iO brush that matches both budget and how much smart functionality a household actually wants. Replacement brush heads add a modest ongoing cost, with multi-packs starting around $29.99 and a recommended swap every three months.
Considering how much of the flagship technology, including the pressure sensor and interactive display, carries down to the lower-numbered models, the value proposition holds up well across the entire range rather than just at the top.
Verdict
Oral-B iO proves that a smart toothbrush can be more than a gimmick, delivering a genuinely smoother clean and useful real-time feedback at nearly every price point. It’s an easy recommendation for anyone ready to upgrade their brushing routine.
