![]() ![]() ![]() The iO7 gives you access to five cleaning modes – daily clean, whitening, gum care, sensitive and intense – which is probably three more than you really need, but it does allow you to play about with the oscillation angle of the brush and the frequency to find the one you are most comfortable with. Out of the box, you’ll get the iO7, one refill brush head, a sleek but robust travel case, a travel brush head holder and a magnetic “click” charger. 1/1 Oral-B iO7 vs Oral-B iO9: Which smart electric toothbrush is best? This revenue helps to fund journalism across The Independent. We may earn commission from some of the retailers, but we never allow this to influence selections, which are formed from real-world testing and expert advice. We took this into consideration and rather than focusing on the similarities between the two brushes (like pressure sensors and two-minute timers) we looked at what set them apart, focusing on the brushing modes, customisation, the limitations of the AI and overall charging. ![]() Of course, all this talk of AI, gyro sensors, accelerometers and frictionless magnetic drives has an impact on the price tag – there simply isn’t a more expensive brushing experience out there. Inside the handle of the iO toothbrushes there is both a gyro sensor and accelerometer, and a portion of Oral-B’s development period was spent collecting data on people’s brushing habits so that the algorithm could accurately read where the brush was in the mouth of the user and interpret it to show how effective their brushing had been. This may seem like an over-complication, but neglecting the harder-to-reach surfaces of the mouth, like the underside of the molars, is one of dentists’ biggest gripes. The iO9 can even track 16 “sub-zones”, meaning it’ll know if you’re getting to each surface of every tooth. This means there’s an accompanying app that tracks how you brush each zone of your mouth. We’ve no idea what happened to one through to six, but we assume this could be a bit of a gimmick to draw attention to the fact that the iO is the result of six years of product research.īoth brushes are enabled with what Oral-B calls “AI brushing recognition technology”. However, all the brushes (iO7, 8 and 9) were launched at the same time and offer different cleaning options and price points. One of the biggest misconceptions that consumers have about the range is that the iO9 is simply the latest, and therefore the best, model. The technology also makes the brush much quieter, which is a bonus if you have to get ready in the morning before other household members have woken up. However, the iO range adds micro-vibrations (created by a frictionless drive system, powered by magnets) to address one of the biggest complaints that people have with powered brushes – that they can be too harsh on teeth and gums. When Oral-B launched its iO range in August 2020, we learned what was going to set these powered toothbrushes apart from the rest: micro-vibrations.įor a while now, the brand has relied on oscillating heads to provide a “deep-clean” feel. ![]()
