Oral B has announced three new iO toothbrushes which will launch in the US in 2022. The new flagship brush is the iO10, while two more budget-friendly models, the iO4 and iO5, are also on the way.

The iO10 will come in two colours: cosmic black and stardust white, which have a star-flecked, spacey design. Like the previous flagship, the iO9, the iO10 will have a full colour OLED screen with a brushing countdown, battery life and settings display, and brushing feedback in the form of an emoji-like happy or sad face.

The iO10 comes with what Oral-B is calling iOSense, a new virtual brushing coach that will deliver real-time brushing help as well as feedback. 

The big change is the incorporation of the charging base into the coaching aspect of the brush. This means that, although the iO10 is app-compatible, you won’t need to open the app to get that feedback.

The charging base – which has a digital display and light bar display – will show the brushing countdown, pressure sensor information and which part of your mouth you should be focusing on.

However, this does mean you’ll need to have the charging base in view while brushing. So, if you don’t have a handy, dedicated spot near a shaving socket to keep your toothbrush plugged in, the iO10 might not be any more helpful than others in the range.

Still, the innovation we really like in the iO10 is the Power2Go charging travel case. If this is anything like the versions offered with the Sonicare DiamondClean 9000 and the PomaBrush, it’ll be a case with integral USB charger – which is the upgrade the iO series of brushes really needs.

A USB charging option was really the only thing we missed when testing the iO9.  

The iO10 also has a souped-up pressure sensor, with additional white and green settings to let you know if your brushing contact is too light or just right (as well as red to indicate that you’re brushing too hard). It’s also one-upping the iO9 with seven brushing modes.

There are no specifics yet on its price point or launch date.

The iO4 and iO5 are new additions at the affordable end of the iO series. Both will cost under $100 and will feature the new iO cleaning head system, which rotates and vibrates, plus a pressure sensor. However, the iO4 will be a basic, pared-down brush, without the OLED screen or app-compatibility. The iO5 will be a connected model.

The new models will sit below the iO6, which is currently the most affordable iO model. It’s available for or £110 in the UK.
