I’ll come on to how that affects the user experience in more detail below, but aside from this, there is really no discernible difference between the design and features of the two toothbrushes. As with the Genius 9000, it then takes you through a daily care routine, letting you log whether your gums are bleeding and whether you have brushed your tongue.

With that in mind, it helps to have the phone near eye level, or you’ll soon find yourself tilting forward to watch the on-screen feedback. In addition to the standard charger, you get a luxury travel case that carries the handle with up to two heads and that also doubles up as a charger. Having spent several weeks using the device, it’s clear that it offers impressive insights into your brushing technique, but I’m still not entirely convinced it’s worth paying extra for.Like the older model, the Genius X then gives live feedback on your brushing, showing which areas you’re targeting. Crucially, I found the on-screen visualisation much more likely to correspond with my actions when using the Genius X compared to the Genius 9000. Like the Genius X, it uses built-in sensors to offer real-time feedback on which areas you’ve brushed and comes with a luxury travel case. Indeed, it’s only after you’ve finished brushing that the app gives both coverage and overall brushing scores along with a summary of how long you spent applying too much pressure. For a start, the process is more seamless as you don’t have to mess around with mounting your phone in a dedicated holder so it can use its front camera to assess your brushing style.

Both have two physical buttons: one for powering the handle on and one for switching modes and pairing the toothbrush with your smartphone. Where the Oral-B Genius 9000 comes with four brush heads, it’s also worth pointing out that the Genius X comes with just one and there’s no phone holder or brush head holder. Now it’s easier than ever to brush like your dentist recommends for a superior clean, for healthier gums. But the Genius X goes one step further, using built-in sensors to give detailed feedback on which areas of your mouth you’ve neglected.

The other main problem is that despite having sensors on-board, the Genius X’s brains are still in your smartphone.
