Overview Of The Oral-B io9 Toothbrush

The Oral B io9 is a rechargeable electric toothbrush that uses oscillation and rotation to clean your teeth.

It has a pressure sensor to alert you if you’re brushing too hard, and it also has a whitening mode, which aims to remove stains from your teeth.

The Oral B io9 comes with an included brush head for whitening purposes as well as an indicator light (that lights up when charging) so that users know when they’re charging their device.

The device itself is small and lightweight.

It can be used both in the morning or before bedtime and comes with several different modes of operation:

  • Normal Cleaning Mode
  • Deep Cleaning Mode
  • Kids Cleaning Mode

Pros & Cons Of The Oral-B iO9 Toothbrush


  • It has a wide range of settings, including a timer setting that allows you to time your brushing in 30-second intervals. This is ideal for people who have trouble remembering to brush at the same time every day or don’t like the idea of having their teeth brushed by an electronic device like an alarm clock.
  • The Oral B io9 toothbrush comes with several different modes and settings so you can customize your experience as much or as little as you want—it offers up to 10 different levels for sensitivity and even includes a whitening mode (which I’ll talk about later on). This means that if one method doesn’t work well for you, there’s another option available!


It takes a little time to get used to.

Price Of The Oral B iO9 Toothbrush

The price of the Oral B io9 toothbrush is $100. This is a bit more than you’ll pay for other models, but it’s also one of the most affordable options on our list.

You can buy it at Amazon or Walmart, where you’ll find variations in color and design as well as shipping costs depending on your location.

If you’re looking for an electric toothbrush with all-around performance and high ratings from customers, then this might be a good choice for your purchase!

Where To Buy The Oral B iO9 Toothbrush

You can buy the Oral B bio9 toothbrush at Amazon. It’s also available at Walmart and Target, as well as other online retailers like Newegg and Best Buy.

If you want to save money on your purchase, however, we suggest buying it from Amazon instead of another retailer like that because they will often offer promotions on their site that make it easier for customers to get a good deal on products like this one!

Is The Oral B iO9 Worth The Price?

The Oral B Bio9 is a great choice for people who want a quality electric toothbrush. It’s more expensive than other electric toothbrushes, but it has a lot of features that make it worth the price.

For example, the Oral B Bio9 comes with three modes: white, sensitive and gum care (the latter two are available only with an extra brush head).

The white mode works well for people who don’t mind mild whitening effects or want to brush their teeth more thoroughly than they would in normal mode.

The sensitive mode is designed for those with sensitive gums; this will reduce brushing time while still getting all of your teeth clean at once!

The Gum Care mode is great if you have braces or implants because it removes plaque from around them before brushing on top surfaces like front ones as well–meaning less pain during brushing sessions!

Who The Oral B iO9 Toothbrush Is For

The Oral B io9 is for people who want a toothbrush that’s more than just a regular old brush. It’s smart, it has Bluetooth, and it even has an app.

The Oral B iO9 toothbrush is meant to be used in conjunction with the Oral-B App (free), which allows you to track your brushing habits, find out how well you are doing at keeping your teeth clean, set timers based on when you wake up or go to bed (or both), and more.

You can also use this app as a way of tracking whether or not someone else should share their toothbrush with you if they don’t have one themselves—or vice versa!

Who The Oral B iO9 Toothbrush Is Not For

The Oral B io9 isn’t for everyone. If you have sensitive teeth, for example, the bristles on this toothbrush may be too aggressive for your mouth.

Additionally, if you prefer manual brushing and don’t mind having to do it yourself (or even prefer a softer brush), then this model may not be right for you either.

Finally, if smaller or larger heads are important to you—and they should be!—the size of the handle and other components are very important as well.


We hope you found this review helpful in making your decision on whether or not to buy the Oral B io9.

The Oral B io9 is an excellent toothbrush that can provide you with the best oral health care possible, but it’s not perfect.

If you don’t mind paying a bit more for quality products and services, then this may be just what you need.
