Automated devices have replaced manual devices with the advancement of technology. Likewise, you’ll see various electric and manual toothbrushes on the market. According to the American Dental Association, electric toothbrushes offer better oral hygiene and a quick way to keep your teeth/gums hygienic. But most of you might be confused about which brush is effective at removing plaque and preventing your teeth from other diseases/decay. Most dentists recommend brushing your teeth twice daily for good oral care, preventing plaque and other teeth/gums diseases.

The kids’ edition and colorful design of many electric toothbrushes attract your kids and help them to clean their teeth and gums properly and effortlessly. Moreover, it might be frustrating for you to supervise your kids while toothbrushing, but with this electric toothbrush, your children will be automatically engaged.

Also, your manual brush lifetime is just a month, after which you’ve to change it while these electric toothbrushes might look a bit expensive, but you don’t need to throw them away after a month. The electric toothbrush, compared to manual toothbrushes, comes with changing heads, so if your toothbrush bristles become frayed or at least every three months, you’ve to replace them, so there is less waste of money.

One more advantage of the electric toothbrush; it comes with light sensors, so if you harshly brush your teeth, it’ll notify you to brush more gently. Like that, each electric toothbrush has its unique benefits, but due to the vast range of electric toothbrushes on the market, you might be unable to decide which one is suitable for you.

Don’t worry, as in this article I will tell you my personal about Oral-B iO series nine review; highly recommended and trustworthy company. This article will help you a lot to find the best electric toothbrush for our teeth or gums problems: So, let’s continue to read this informative article:

How much does this toothbrush cost?

As you all know, Oral-B is a top-notch company that hasn’t made its brushes easy to under, so in this article, I’m going to share every single point of this Oral-B iO Series 9 review. In 2020 Orab-B released its iO series, which includes series 6, series7, series 8, and series 9.

Also, you can purchase this toothbrush with a bundle of brush heads which may cost you around $330. You might become astonished after listening to such a high price. Still, you’ll find it on sale if you shop around the official Oral-B website, eBay, or Amazon.

The magnetic charger of this toothbrush easily connects with the typical shaving plug, brush head, and carrying case. Moreover, its rechargeable carry case helps you to keep the brush charging full even you’re away from home. This charging case has enough space to hold a brush handle and its head.

When we compare the design of this Oral-B iO Series 9 with other complicating toothbrushes, it offers more simple controls; two buttons for switching on/off the brush. By quickly removing it from the charger and pressing the lower button, you can select its cleaning mode and then press the power button to start it. The user-friendly OLED interface makes it easy to choose your desired mode out of the seven cleaning modes.

Less use of plastic in this Oral-B series nine toothbrush makes it an eco-friendly electric toothbrush compared to others. Moreover, when I use this toothbrush to give this Oral-B iO series nine reviews, the first thing that strikes my eyes is its light choosing option. This option is not for personalization but acts as a pressure sensor, so when the standard red light blinks, it means you’re pressing the brush harshly with extra pressure. However, you’ve to select the green light, which indicates moderate pressure that is best for your teeth. Moreover, this light sensor also indicates the change in a light color; red means too much pressure, and blue means not enough pressure.

The handle of this electric toothbrush is in a standard cylindrical shape, but its front and back design are smooth to touch and look very refined. The sleek design and lightweight of this toothbrush handle prevent it from rolling over your countertop like other brushes. This handle has an oval panel on the front integrated with the power button, colored OLED display, and cleaning mode button. The concave design of these circular buttons makes it easy to fit above and below the OLED display. Under this oval panel, there is a silver/grey-colored Bluetooth logo. At the bottom of the handle, you’ll find the Oral-B and iO logos in the same color.

Moreover, the silver-colored ring around the bottom edge and the top of its handle enhances its stylish design. The base of this handle is slightly concave, conveniently fitting into its charging stand like most other Oral-B brushes. It’s straightforward to connect the brush heads with the handle as the handle acts as a shaft in which you can quickly push/pull your brush head to connect it; there is no need to twist them. Its brush head bristles are blue and white to match each color of this Oral-B iO series nine handles.

The brush head is small and round, and each toothbrush comes with two types of iO-specific heads; ultimate clean and gentle care heads. Just like Oral-B older toothbrushes, the brush heads of this series nine also have the indicator in their bristles that indicate you to change the brush head when it is frayed. However, if you brush your teeth twice a day, the blue color of the bristles may also fade within three months; after that, you’ve to change your brush head. However, If the bristles frayed before the color fades, it’s a sign that you’re exerting too much pressure on your teeth and gums. Moreover, if you want to know more about Oral-B brush heads, you can visit the Electric teeth website.

Which cleaning modes does it offer?

This Oral-B iO series 9 offers seven cleaning modes in total, which are as follows:

  1. The most commonly used cleaning mode is “Daily Clean,” which would last for not more than 3 minutes. 
  2. If you’ve sensitive gums/teeth, this “Sensitive mode” is perfect for gently and thoroughly clean your sensitive areas.
  3. Do your gums bleed? Then this “Gum Care” mode works best for you as it gently massages your gums and takes good care of them.
  4. Are you going for a dinner or party and want white teeth instantly? Then this electric toothbrush’s “Whiten” mode works best for polishing your teeth.
  5. If you want some extraordinary oral cleaning, then its “Intense” mode works well for giving you a cleaner feeling. Warning! It is operated at a higher speed than usual.
  6. If you’re an old person looking for an electric toothbrush that works well on your extra sensitive teeth, then the “Super Sensitive” of this toothbrush offers you super gentle cleaning to your extra sensitive areas.
  7. Moreover, this toothbrush also offers a “Tongue Cleaning” mode that would last for no longer than 30 seconds. 

Each mode is designed with a fixed time, after which the brush automatically powers off.

How can you track teeth cleaning?

According to most dentists, up to 80% of people spend much time brushing only one zone of their mouth. On the other hand, around 60% of people forget to brush their back molars or don’t spend much time brushing their teeth.

With the Oral-B iO app readily available on the Google play store, you can easily track your oral cleaning. On the app, you’ll see a 3D view of your oral cavity, letting you know which surfaces in your mouth are left to be cleaned. But this “3D tooth surface tracking” app is designed just for standard oral cavity structure, so if you’re less/more teeth than usual, this app won’t show them.

I must say that it works well in cleaning most positions of my mouth. Moreover, due to some bug, the app started late on my mobile while I’ve already started cleaning, but as soon as the app started, it aware me that I had forgotten to clean the upper left part of my mouth. So, not if you don’t want to forget your mouth parts, then you must follow the KAI method that most dentists recommend. In this method, first, you’ve to clean the chewing surfaces, the outer surfaces, and the inner surfaces at the end. In this Oral-B iO series nine review, I’ve mentioned two methods; with and without an app for tracking mouth cleaning, which is as follows: 

With app

Oral-B iO series nine brush can easily be connected via Bluetooth by installing the free Oral-B iO app available for iOS and Android. But it might be tricky for beginners to connect this app with their smartphone and toothbrush. So, here I elaborate on this process for you first install the app from the Google play store and then activate Bluetooth on the smartphone.

Open the app and start; now select cleaning mode on your toothbrush and simultaneously press the start button and timer on your mobile. This 3D cleaning tracking app will automatically detect where your toothbrush is currently moving in your mouth. After that, you can switch off your toothbrush, and the app must display a score of 100/100; if it doesn’t display 100/100, then the app will give you feedback to improve your brushing skills. If all lines on this tracking app disappear and all teeth look shiny, you’ve successfully cleaned all areas of your oral cavity. 

Without app

With this method, you can brush your teeth without the app. Most of you might be thinking at this moment that how’s this possible with an app? So, your toothbrush has imprinted controls and a timer on display. Moreover, the handpiece vibrates every 30 seconds, which acts as an indicator; when you are stuck on to clean only a single. And according to the dentist’s recommended time, this Oral-B toothbrush will take a maximum of two minutes to clean the top left, top right, bottom left, and bottom right areas of your mouth.  


The battery life of this Oral-B series nine toothbrushes is inferior to most of its competition, like the latest models of Genius 9000 and Genius X offer around two weeks of battery life. Moreover, Sonicare electric toothbrushes offer around 2-3 weeks. However, the battery of this toothbrush claimed to be more than two weeks. After using it on daily clean mode (2 minutes), the battery lasts only 11 days. It can probably offer 14 days of battery life which equals 28 times brushing sessions with just a single charge. So, on the whole, we can say the batter-life isn’t that bad but not as good as most of you’re hoping. 

Cons of Oral-B iO Series 9

  • Work only with iO-specific heads, which are more expensive.
  • Much pricier than other models such as the Genius or Smart.
  • The battery drains quickly.

Wrap Up!

After reading this Oral-B series of nine reviews, you might have decided whether this product is suitable for your oral health or not. Besides all its flaws, this Oral-B toothbrush offers gentle and thorough cleaning with the help of its cleaning modes to those with sensitive teeth and gum disease. I’m sure that after purchasing this top-tier product, you won’t regret it, and it’ll undoubtedly take good care of your oral health without causing excessive bleeding or inflammation. However, if your budget is low, you can go for some other options. But if you want to buy this product, you can easily purchase it from Amazon.
