The iO travel case could be executed better. It's certainly handy to have a protective case when you go away, but this one only has space for one brush head. If you need to take another, you'll have to bring the refill holder along as well. After each brushing session, remove the brush head and thoroughly rinse both the brush head and the handle under running water. 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. The actual charging cord for the case is quite bulky. Rather than a simple USB cable, which some other toothbrush charging cases have, this one uses an adaptor which is almost as bulky as the regular charging stand. Oral-B offers a variety of replacement heads to ensure you can find the one that best suits your oral care needs. The below brush heads fit all of our electric toothbrush handles (except Oral-B iO). Browse below our entire line of Oral-B replacement brush heads.

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. 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. iO Ultimate Clean: tuft-in-tuft structure with 16 degree-angle bristles remove up to 100% more plaque for cleaner teeth and healthier gums*

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. 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 clean Sensitive Clean: for a gentle clean, comes with ultra-thin bristles that are tough on plaque but gentle on gums Interspace: to be used on top of your daily brush head, for deep clean in hard-to-reach areas and healthier* gums To fix this, try running the toothbrush’s top section (around the plastic connector and metal shaft) under warm water for at least ten seconds. Then, see if you can pull the extra bit off. You might have to give it quite a forceful tug, but it should come right off. If it does, your new brush head should fit.

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. 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.Oral-B have developed a new app to go along with this brush with a revised design incorporating the Brushing Recognition AI. If you have it open as you brush, it displays your progress in real-time. Once you finish, it gives you an overall score based on your brushing time, coverage, and pressure. 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. This is not a completely novel idea; the Oral-B Genius X and Sonicare DiamondClean Smart both offer similar technology. 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.
