My dental hygienist recommended this toothbrush about nine months ago. When I mentioned how expensive it was, she said, “It’s still cheaper than getting a filling.” That changed how I looked at the price, so I went for it. The guided brushing app takes the guesswork out of whether I’m actually brushing everywhere. I used it twice a day in the beginning, which really helped me build better brushing habits. Nine months later, I don’t use the app every time anymore, but I still check in here and there to make sure I’m staying on track. The pressure sensor is also super helpful! My dentist mentioned that many people damage their gums and teeth by brushing too hard, and this makes it very obvious when you’re using too much pressure. I’ve had two dental cleanings since switching, and both were probably the quickest I’ve ever had. My dentist and hygienist said everything looked great with very little cleaning needed and mentioned they commonly see this with patients using an Oral-B iO. The brush heads indicate when they need replacing, which for me has been roughly every three months. They’re about $10 per replacement head, so that’s another ~$40 a year to factor into the cost. Not cheap, but reasonable enough for me considering how well the toothbrush has performed. My only complaint is that it’s can be a bit messy. Even after rinsing the head and shaking off excess water, some water/toothpaste tends to run down the handle once it’s on the charger, so I clean the charging base a couple times a week. It’s definitely an investment, but after nine months of daily use and two great dental checkups, I’m very happy I bought it.

I'm new to electric toothbrush & it took me a minute to get use to this but once I did, I am very, very happy with it! At first it seemed like it wasn't brushing my teeth with much of the toothpaste (it kept slinging it everywhere in my mouth) but to fix that I manually brush the toothpaste on my teeth (just enough to cover my teeth with it) then turn on the brush. That is the freshest my mouth & teeth feel. It's as if I'm coming out of the dentist every time (& that is a great feeling!). My teeth are WAY cleaner & even stains are nearly gone (I drink a lot of dark drinks). It'll stop/vibrate every 30 seconds to let you know to switch to another side of the mouth. I also love how it tells me if I'm pressing the brush to lightly or to hard on my teeth (the colors will tell you, green is good). The spin is powerful & toothpaste will be slinging out. I always turn it off before I take it out of my mouth because it slings so much. I love the multiple settings you can choose but I always choose the sensitive option. It's not as strong as the daily clean option (daily clean was irritating my gums). The charge lasts a good while. I still use manual brush sometimes & I don't use the Bluetooth stuff so my charge lasts longer. I bought this in December & only had to charge it once. So if you use it more than I do you might need to charge it 2 or 3 times a month. Although I don't travel, I like that it came with a travelling charging case. I just see it as an extra charger in case something happens to my regular one. If you decide to buy I recommend looking at every electric toothbrush from this brand & comparing the cleaning options that are available for each one (I love how this one had a lot to choose from). They made it extremely easy on Amazon for me to compare them. The cleaning options you're interested in might result in a cheaper brush, you might not be interested in multiple cleaning options. Also compare the Bluetooth stuff. I don't care about the extra blue tooth stuff so I got this one which is cheaper. Whichever brush you choose, I'm sure you will not be disappointed. This brand is fantastic & I would definitely buy from them again whenever my brush is done for.

I've had this now for nearly a year and it's been working well. The built in 2 minute timer with vibrations are great for knowing when to move on from the sections of the mouth. Wish the brush heads would last a little longer but they clean fairly well. Many different settings that you can choose to brush teeth from super sensitive to daily clean or gum care. I do keep my brush on the wireless charger all the time but I've been able to take it on trips without it running out of power, and I bring the travel case just incase but never had to use it. I would recommend this to get your brushing habits fixed if you have a hard time of sticking to the brushing schedule.

Overall Satisfaction: I give the Oral-B iO Series 9 a solid 5. This toothbrush is amazing and well worth the higher cost compared to other series. Main Purpose: I purchased this toothbrush to maintain optimal dental health and minimize the need for extensive dental procedures. Ease of Use: The toothbrush is excellent, and you can even turn on the phone to track your performance. It offers awards for meeting specific goals, some of which can be challenging to achieve. Performance: The Series 9 comes with additional sensors and a flat magnetic mount for convenient charging. While the battery drains quickly, it's not an issue for short 2-3 minute sessions. Features: The ability to visually track cleaning habits is a standout feature. With multiple modes available, I typically use sensitive, whitening, or daily settings. Durability: The toothbrush is very durable, and despite the quick battery drain, it's not problematic for regular use. Value for Money: Although expensive, the toothbrush pays for itself when considering the savings on dental bills, primarily limited to cleanings. Comparisons: Compared to other Oral-B models, the Series 9 is more advanced, with the phone app being the most significant difference. It provides detailed information about brushing habits and areas that need improvement. Pros: Maintain Oral Health: Keep your teeth clean and healthy with advanced features. App Integration: Track your brushing habits and receive feedback on the app. Charging Options: Charge the toothbrush using the magnetic mount or the convenient travel case with an attached cable. Cons: Lack of Apple Watch Compatibility: It would be more convenient if the toothbrush worked with the Apple Watch, eliminating the need to pull out the phone for information. Additional Tips: For a clean toothbrush and to avoid hardened toothpaste, use the travel charger instead of the magnetic mount. Cleaning the head after each use and washing it with water is also recommended. Recommendation: If you're looking for a top-notch toothbrush that not only ensures oral health but also provides insightful data through a dedicated app, the Oral-B iO Series 9 is worth the investment.

I bought the Oral-B iO Series 9 expecting a premium product. The toothbrush itself has a lot to recommend it, but the charging base has one of the worst design flaws I have encountered in a consumer product. The iO9 is a relatively tall, expensive electronic device, yet while charging it essentially balances upright on a small, shallow magnetic base. There is no meaningful post, socket, collar, or other mechanical support to keep the handle from tipping sideways. Because the handle is so tall, it takes remarkably little lateral force to knock it off the charger. This isn’t a hypothetical concern. I had a previous Oral-B toothbrush fall from its charger and break. With this one, I eventually stopped keeping it conveniently in the bathroom because I didn’t trust the charger to keep it secure. I actually improvised a second magnetic support against the handle when I kept it elsewhere, which dramatically improved its stability. What makes this especially frustrating is that the problem is neither difficult to foresee nor difficult to solve. Competing electric toothbrushes use charging designs that mechanically locate and support the handle. Even a modest post, recess, collar, or other positive restraint could dramatically reduce the chance of an expensive toothbrush being knocked onto a hard bathroom floor. For a flagship toothbrush at this price, this is particularly difficult to excuse. Oral-B put enormous engineering effort into the iO’s display, sensors, pressure detection, Bluetooth connectivity, brushing modes, and app integration. The company should have put comparable thought into the much simpler requirement that the toothbrush remain standing securely while it charges. Prospective buyers should know about this before purchasing because it isn’t something obvious from the feature list. If you buy one, be very careful where you place the charger

This toothbrush is really great. My teeth feels clean just like after a visit to the dentist. The only reason why I didn’t give 5 stars it’s because for some reason it keeps sending a message on my phone to change the head. This message was showing on the second day after use, like I had used the brush for many hours. Maybe it is a software problem that can be solved with an update. Also there is no option to turn it off. So it seems to be on for longer than it should, wasting battery. The battery life is good. Im traveling for almost 2 weeks now (12 days) and didn’t need to charge it yet. The app is cool but unpractical to use every day. It would be nice if they could make a change to record the data without the need to open the app on the phone. Like smartwatches do with activities, etc. The green light really helps me not to use too much strength which was a problem I had. The travel case could be charged with a usb. For travel purposes it would be nice not having to carry another charger just for the brush. Overall I’m very happy with my purchase. It is an expensive brush indeed, but for me was totally worth it.

I have always struggled to brush regularly and had reached a point that gingivitis was winning the war causing deep pockets to form in my gums. After a thorough deep cleaning of my teeth and roots, I invested in this toothbrush. The toothbrush works great. And after changing a lifetime of bad brushing habits, my deep pockets are gone. Instead of pocket depths of 5’s through 7’s (very bad), I’m now back to 1’s through 3’s (normal range). Good brushing habits paired with a great toothbrush will yield great results. Regarding brushing habits, I credit this toothbrush for making the process easier. Instructions of 2-3 seconds on the front, back and tops of the teeth don’t get much easier than that.

and maybe the best brush i’ve ever had as well. i was using oral-b’s io series 5, which is 100% cheaper than the series 9 at the time of this review, for 2 years almost and i really liked it. would say my mouth and teeth have never looked and felt cleaner. i decided to upgrade to the series 9 bc it has gone on sale, and this definitely makes my mouth feel even cleaner than the 5 series. i don’t think you should believe people when they say everything in the io lineup cleans the same, because in my experience the series 9 is superior. i’m not sure which motor sounds more quieter, the 5 or the 9, but it does sound similar to me. for what it’s worth, i heard that the series 10 has the quitest motor out of everything in the lineup. but i will use the series 9 for the next 2 years at least.
