This toothbrush is a total game-changer! Every time I use it, it feels like I just had a professional cleaning at the dentist. It’s powerful enough to leave my teeth feeling incredibly clean, but still gentle enough that it doesn’t cause any pain or discomfort. The battery life is impressive — it lasts a long time between charges — and the travel case makes it super convenient to carry around while keeping it protected and charged. I love not having to worry about losing it or finding a place to recharge constantly. Overall, it’s easily one of the best toothbrushes I’ve ever used!

Best tooth brush I have ever owned it’s not just a toothbrush it’s definitely in another level I actually get a dentist clean feel everyday that I use it it’s one of those things that you didn’t know you needed it till you got it and now you can’t go without it kinda of thing yes it’s insanely expensive but for what it does I feel like over time with consistency you could potentially have less dental visits because your getting your teeth and gums throughly clean daily sometimes 2x a day will help to keep them healthy thus saving you money

This is the worst electric toothbrush I have ever owned. The iO brush heads are different than the older Oral-B design. These iO brush heads have two holes at the top that allow prolific amounts of toothpaste and saliva to enter inside the stem on the brush head. But what is even more flawed is that there is a large third hole at the base that allows a lot of the toothpaste to leak out while brushing your teeth. This design makes it difficult to use without making a mess everywhere. The head design is also harder than it should be to keep clean, and quite frankly, it seems unhygienic to me.
The connected app is somewhat of a gimmick to me. It always says that I am missing spots that I clearly and thoroughly brush over. I stopped using the app after a few weeks.
I just switched back to my older Philips Sonicare. Not only do my teeth feel better after brushing with the Sonicare, but it was an absolute pleasure not to have messy toothpaste leaking out of the base of the brush head and making a mess everywhere while I brushed my teeth.
Buying this toothbrush was a complete waste of money. I plan to stay with Philips Sonicare from now on.

Expensive toothbrush. But worth the money for long-term dental hygiene it’s like I took a drill to my mouth. It was a little overwhelming at first however, second use was very much easy. I am impressed with how well this toothbrush, my mouth feel clean improvement in my gum, health more importantly, I went on a trip and had to use a normal toothbrush and it just felt completely wrong. I highly recommend this toothbrush as an investment. , I went on a trip and had to use a normal toothbrush and it just felt completely wrong. I highly recommend this toothbrush as an investment to your dental hygiene.

This is possibly one of the best toothbrushes I've ever used. I like the fact that you can also charge the toothbrush via a port conveniently integrated within the travel case.

This toothbrush is incredible! The bristles were a bit tough at first but I just used it on sensitive mode until they broke in. Always leaves my teeth feeling amazing!

Great toothbrush with multiple functions. It makes your teeth feel as if you just left the dentist. With having braces, the circular motion of the brush assures me that I am getting in all of the crevices.
I would recommend this to a friend

I love this toothbrush. My last Oral-B has lasted 12 years. I actually would’ve lasted longer than that I just wanted to buy this new or updated model. I love the app because there’s so many newer options on it and it shows you which teeth you have brushed and if you spent enough time on each tooth to actually get it cleaned.

Lets start this review with what's most important, how well it works. For cleaning teeth, nothing I've ever used has ever come close. Regular toothbrushes aren't even in the same league. I also own a very basic and cheap Oral-B electric toothbrush, the kind that just has one single speed and a simple on button, and it's still a night and day difference. After just one brushing, my teeth felt almost the same as they do when I leave the dentist after a professional cleaning. They just felt glossy smooth.
The features this toothbrush comes with helps with that, especially the companion app. If you open the app before you start brushing, connect via bluetooth, and press brush now, it'll communicate AS YOU BRUSH! The coolest part about it is it shows a diagram of teeth, and the brush actually senses its position and knows what area of teeth you're brushing. It then displays graphics around that area of teeth on the phone and slowly turn white as you brush. This feature alone makes you want to fully brush to get all those teeth showing white.
Yes, they've game-ified brushing teeth, but that gamification makes something mundane into something fun. The app even has achievements.
Take away the app though and its still pretty amazing. The vibration and motion of the brush is strong. Almost too strong to be honest. I have to use it on sensitive and even in that mode I worry a bit about one of my crowns vibrating off. Not sure if that's a justified fear, but it really is that strong. Plaque honestly doesn't stand a chance though.
And speaking of plaque, this brush is EXPENSIVE. What do those have to do with each other? Well, it's honestly tough to swallow paying 300 dollars for a toothbrush. In this case though, if it can prevent just one deep cleaning (of which I've had multiple using lesser brushes), it more than pays for itself. That's what makes paying so much for a toothbrush worth it. I have no doubt whatsoever that this will save some of those non-routine dentist trips.
The brush heads are of course replaceable, which the app can remind you when its time, and this brush comes with 4 in the box. This makes it easy to share. In fact, both me and my wife have been using this toothbrush, each of us having our own brush head. This makes the price an even better deal.
There is a downside though to sharing the brush, the app doesn't know who's using it. When you don't brush while communicating with the app, it considers it "unguided", but it still keeps a log of these sessions with some basic info. So if someone else uses the brush, it'll log it all as if it were you. Overall its a pretty minor downside.
That's about it for downsides though, only other one, if you can call it that, is that even though this has 9 different modes, I honestly can't tell much of a difference between some of them. Others you can definitely tell, like Intense and Sensitive.
One last item I want to mention is the travel case that this comes with. As a frequent traveler, this case is a huge convenience, but even more so because it's an actual charging case that comes with a separate power cord so you don't have to move the regular one from your bathroom. And speaking of charging, I've been using this toothbrush for almost a week now and it still has 40% charge, so you don't even need to charge it if you're only taking a weekend trip, or even a weeklong one, as long as its fully charged before you leave
Overall I was surprised with how much I like this toothbrush, especially considering the high price. That alone made me want to initially dock a star for it, but as they say, you get what you pay for and you definitely get your money's worth out of this one.

I’ve used other electric toothbrushes over the years but settled on an Oral-B Triumph Pro unit that’s been working great for many years, though it’s starting to show its age. Getting this latest Oral-B iO Series 9 Electric Toothbrush almost feels like getting my teeth and gums cleaned by a dental hygienist every day. I don’t know how it does it, but my teeth, gums, tongue, whole mouth feel so clean and fresh after each 2-minute session that I’m never going back to using a regular manual toothbrush. The smooth vibrations and rotations of the brush head almost create a feeling of gentle water pressure/swishing in your mouth, resulting in a very refreshing feeling. Make sure you close your mouth as much as possible, or you’ll be splashing your vanity mirror quite a bit.
The setup and use is very intuitive. The magnetic charger is great and the travel case with built-in charging feature is a welcome addition. The built-in color display is bright, easy to use and very informative, including battery life. I especially like the color ring around the top of the unit that lights up green when brushing correctly, and red if you’re applying too much pressure. It comes with 7-modes of operation for everyone’s brushing needs: Daily Clean, Gum Care, Sensitive, Whitening, Tongue Cleaning, Intense and Super Sensitive - it will vary the speed and intensity of the vibrations and rotations for each mode accordingly. Battery life seems great so far, in my estimations, it consumes about 5% per brushing cycle, which technically could allow for 10-days of brushing twice per day.
It is considerably smaller and lighter than my older Triumph Pro model, but it feels a bit slippery in hand as it’s all smooth plastic, no rubber grip. The brush heads are actually bigger and bulkier than the older models, so that could take some getting used to. There is also no longer a color ring you could attach at the base of the brush head to distinguish between yours and hers/his, if you were sharing the electric toothbrush handle with your spouse. Unfortunately, I can’t speak for the app, cause I could not get it to “pair” with the brush, even though I tried quite a few different things, several times. It just gets stuck at the “Found” screen after detecting the toothbrush, and there is nothing else you can do from there. Judging from other people’s success with the App, it must be an isolated issue pairing it with my S20 Ultra, so I’ll have to take 1/2 star off for that contact support for help. I would definitely recommend it, if you can afford it.

Great product and will recommend, however Best Buy shipped me a used product which I was disgusted by, I didn’t realized until I saw old data from the previous owner still synced to the toothbrush on the oral b app. I payed full price for a used item, I will be returning this item and taking my future business else where

The item showed up in a box that looked like it had already been opened. It was sealed with regular tape instead of the usual factory seal, which made it feel like a return or previously used product. Pretty disappointing, especially when you're paying for something brand new.

I prefer the motion of the Oral B io over the soniccare, the io motion and round bristle design focuses on one teeth. My mouth feels much fresher and the app keeps track of your brush habits and guides you to how to brush your teeth if required.

COVID-19 alternate to DENTISTS
I was not necessarily in the market for another electric toothbrush, but having now cancelled two dental cleanings this year due to Covid-19 concerns, I came across the opportunity to test the Oral-B iO series 9. The Smart AI features, and OLED screen instantly piqued my interest.
First impressions, premium package opening experience, greeted by a colorful bold friendly introduction to the iO series 9 ships with charging case and 4 brush heads.
Setting up the app was a breeze, particularly useful was the Amazon Dash Replenishment option for additional brush head supplies.
Comparing the Philips SonicCare to the Oral-B iO 9, I have been accustomed to beeps every 30 seconds, with 4 quadrants (top left, top right, bottom right, bottom left) for a 2-minute complete brush cycle.
Since the Oral-B iO 9 brush strongly advocates the use of the app, the graphic for the mouth is broken into 6 zones, 3 top, 3 bottom. The brush vibrates at 30 second intervals, so standard time is 3 minutes brush time.
Keep in mind that you might not have achieve perfect white teeth on the graphic overlay, so it’s not uncommon for perfect 100% clean brushes to take closer to 4 minutes or more.
Apple Health is a big plus for me. Part of the allure of a connected smart toothbrush is to keep track of # of times brushed, when, and average time. Using the app it records this. , This is where I believe this brushing model falls a tad flat.
I found it difficult to invest 3-4 minute brushing 3-4 times a day. If I happen to be in the bathroom without my phone, on a busy day I’m unlikely to retrieve my phone before a quick brush.
So instead of the toothbrush brains able to bluetooth seasons I brushed without the app (or later sync to the app), I couldn’t help but feel I’m leaving holes in my data, like when I don’t get credit for sleep tracking or a work out on Apple Watch.
That nit pick aside, there's a LOT to love here. This brush definitely makes me focus MUCH MORE on my DENTAL HYGIENE. Even little touches like reminder checkboxes that result in additional accountability is a nice touch.
Tongue cleaned, check
Fossed, check
Rinse, check
Compared to a competing brand Electric Toothbrush this one far outshines it. Testing the brush heads, the circular Oral-B also outlasted the competition using similar # of brushes.
-----
This model 9 comes in 3 finishes. It’s interesting to note Purple is only on the series 8
- Rose Quartz
- White Alabaster
- Black Onyx
Though I was hoping for Black Onyx my review sample arrived a rather attractive White Alabaster.
Ring colors
- Red - Too hard
- Green - Just right
- White - too gentle
7 Smart Modes
————————
* Daily Clean+
* Sensitive
* Whiten
* Gum Care
* Intense +
* Super Sensitive +
* Tongue clean
The cleaning modes are intelligent, e.g. gum care uses a different pressure sensitivity, and super sensitive seems to re-calibrate for miniature micro vibrations.
PROS
———
+ interactive color display
+ immediate app response
+ magnetic charger base
+ Apple Health app integration
+ medal reward system (Peloton like)
+ approx 3 hour quick charge
+ base not required, travel case is all
+ Travel case charging indicator
+ battery life is excellent
+ full charge lasts a week
+ pressure sensitivity alert
+ 3d tracking nothing short of amazing
+ clean fresh breath feeling all-day
CONS
———
-must use phone in bathroom, would prefer bluetooth brushing statistics to the app or post-pone sync
-the magnetic base could be stronger, while secure (not kitten proof)
-takes me 3 min to brush vs 2 min normally
-price tag, cost prohibitive to outfit a family of 5
-unable to edit session data if I floss but forgot to check the box
CONCLUSION
———————
The Oral-B iO series 9 is a mixed bag for me. The smart brush, AI features, and mouth mapping are innovative and forward thinking. However I couldn’t’ help but wish that all brush sessions were logged regardless if I used the App. I’m deducting ½ star for that, and ½ for the price, though I know OLED screens do not come cheap.
But the Good (GREAT actually) definitely outweigh little nitpicks, and it could possibly be updated via firmware / app update. I've not had the fresh clean teeth feeling this great since my last Pre-COVID-19 dental cleaning.
ORAL-B is onto something there, and this is just the beginning of the connected toothbrush revolution. I eagerly look forward to future surgical tools that use this technology, like tissue pressure sensitive scalpels, and the like.
Solid recommendation

Let me start of by saying that as an adult I have never been so excited about brushing my teeth until now. The Oral-B iO Series 9 connected rechargeable tooth brush made something that seemed like a chore in the morning into a fun and exciting experience while cleaning your whole mouth.
I have used many electric tooth brushes before but none of them compare to the Oral-B iO series 9. The Oral-B is an Ai based tooth brush and 3D teeth tracking, which shows which areas of the teeth you have and cleaned and how well you cleaned them. It also shows you if you are applying too much pressure on your teeth and gums while cleaning. This tooth brush is packed with multiple features such as 7 different cleaning modes ranging from Sensitive+ to Intense+, tongue cleaning, smart pressure sensors, and to top it all off a full color display which greets you with smiley face when you turn it on.
Setup
The setup for the tooth brush was pretty simple. You start off by downloading the Oral-B app on your phone and the with the press of the power button the tooth brush connects your phone. You are now ready to brush your teeth.
Oral-B App
In my experience the Oral-B app is an essential tool while using this tooth brush. The app shows the 3D tracking of the area and how long to clean the teeth, also at the same time the smart pressure sensors in the tooth brush show you if you are applying too much pressure. Now the first time I brushed my teeth with this I was applying way to much pressure and this toothbrush helped me correct that issue. Now you can also use the brush without the application, but then you lose out on tracking and how well you cleaned your teeth. The app also keeps track of your brush head usage and can remind you when it needs to be changed.
Accessories
The Oral-B tooth brush comes with a pretty nice setup. The tooth brush comes with a magnetic recharging base, a rechargeable travel case (I absolutely love it since I travel a lot), 4 brush heads, and the rechargeable tooth brush base.
Conclusion
I honestly do feel like I am doing a much better job cleaning my teeth with this tooth brush and actually feel the difference as well. It really helps when you can actually see how well and what areas your are cleaning. All in all definitely a much better brushing experience. I would highly recommend this toothbrush.
