This is not a completely novel idea; the Oral-B Genius X and Sonicare DiamondClean Smart both offer similar technology.

The new brush heads are presumably necessary for the new style of motor, but unfortunately they are not compatible with Oral-B's older toothbrushes. Nor are the older style heads compatible with the iO. As has become quite standard on electric toothbrushes now, a built-in timer signals when your brushing time is up and a quad-pacer tells you when it's time to move to a new section of your mouth. For the standard Daily Clean mode, this is set to two minutes broken into four 30-second intervals. You can adjust these settings via the app if you wish.The good battery life means you might not need to charge it while you're away. But considering that the charging travel case is one of the premium features of the iO9, it doesn't really add much to the product. The red light is accompanied by a slight reduction in the motor speed. You can customize the color displayed on the LED ring when the brush is on but not in use; a fun but completely unnecessary feature. It should go without saying really, the iO toothbrush leaves your teeth feeling super clean. You'd expect that from a toothbrush that has six years of research and over 250 patents behind it.

Interspace: to be used on top of your daily brush head, for deep clean in hard-to-reach areas and healthier* gums The way the motor delivers power makes it feel gentler than previous models, too. Not in a less effective way, but certainly less aggressive. Timer and pressure sensor If this is out of your budget, the good news is that there are plenty of other affordable electric toothbrushes around. They may not have quite the same bells and whistles but they will still get your teeth very clean.

iO Ultimate Clean: tuft-in-tuft structure with 16 degree-angle bristles remove up to 100% more plaque for cleaner teeth and healthier gums* There is currently no Oral-B iO series 10, and a release date isn't set for a model with this name. At the moment, available series models are the iO series 6, 7, 8 and 9. Is the Oral-B iO toothbrush worth it? For optimal results, we recommend you change your brush head every 3 months, after you have been ill or when the bristles become worn.

Two extra brushing modes are nice but you'll probably never really use them. The Tongue Cleaner mode is just programmed to turn off after 20 seconds, but you could do the same thing manually with any other mode. And actually, we recommend you try using a tongue scraper if you really want a clean tongue. If you're guilty of scrolling on your phone when you brush and not really paying attention to what you're doing, the app will certainly help you focus. But you do have to be committed to using it to get the most out of it. A charging travel case is a great idea, but unlike many other brands which supply a USB cord, the Oral-B case has a special main charger. This makes it much less compact, taking up almost as much space as the regular charging base. iO Gentle Care: the gentlest iO Refill for a smooth brushing experience. Cushioning outer ring with thinner filaments to protect gums, high density of extra soft bristles for a gentle cleanA timer shows how long you've been brushing for, although it's hard to view this without stopping and taking the brush out of your mouth. The idea is that all of this technology in the iO trains you to brush your teeth more effectively. Over time, you should see your score improve.
