Choosing an electric toothbrush can be a challenge given the wide array of technologies and features available. The Oral-B iO series, in particular, has set new standards in at-home oral care with its magnetic technology and smart features. This article provides a factual overview of the core functions of the Oral-B iO models to help you make an informed decision that suits your individual needs.
Before you buy an Oral-B iO, it's helpful to understand the key technologies and their practical benefits. The following points provide an overview of the most important features.
A common mistake when brushing is applying too much pressure, which can irritate or damage the gums. An electric toothbrush with a pressure sensor is an essential feature here. The Oral-B iO series has a smart sensor that provides direct feedback via a light signal:
This function supports a gentle yet thorough cleaning, which is especially beneficial for people with sensitive gums.
Modern electric toothbrushes offer more than just a standard cleaning mode. The iO models are equipped with various programmes tailored to specific needs, such as "Daily Clean," "Sensitive," "Whitening," or "Gum Care."
Additionally, connecting to a toothbrush with an app (in the case of the iO series, a magnetic toothbrush with an app) allows for a detailed analysis of your brushing habits. The Oral-B app uses AI-powered position detection to track in real-time which areas of your mouth have already been cleaned and which still need attention. This promotes complete coverage and can sustainably improve your brushing technique, similar to a professional-level clean at home.
The Oral-B iO series includes various models that differ in their range of functions and features. Here, we present a selection to highlight the differences.
Why it stands out: The Oral-B iO 10 is distinguished by its innovative iO Sense charging base. This base provides personalised live coaching directly during brushing, showing where, for how long, and with what pressure to brush—all without needing to open the smartphone app.
Pros:
Who is it for? This model is aimed at tech-savvy users who want maximum data-driven feedback and convenience to optimise their oral hygiene without compromise.
Why it stands out: The iO Series 6 offers a balanced feature set, combining essential iO technologies like the magnetic drive, smart pressure sensor, and app connectivity in a more accessible package.
Pros:
Who is it for? The iO 6 is a great choice for users who want to leverage the core benefits of iO technology and value app-supported tracking but don't need the full range of features found in the top-tier model.
Why it stands out: The iO Series 4 is the entry point into the world of Oral-B iO magnetic technology. It focuses on the fundamental features for a superior clean compared to manual toothbrushes, including the precise pressure sensor.
Pros:
Who is it for? This model is ideal for users upgrading from a manual or older electric toothbrush who want to experience the essential benefits of a modern toothbrush for whiter teeth and healthier gums without investing in advanced tracking features.

The main differences between the Oral-B iO series lie in the range of features and accessories. Higher-numbered series (e.g., iO 9, iO 10) offer more cleaning modes, a colour display, more advanced 3D teeth tracking via the app, and accessories like the iO Sense charging base. Entry-level models (e.g., iO 4) focus on core technologies like the magnetic drive and smart pressure sensor but omit some of the advanced digital features.
The smart pressure sensor in Oral-B iO toothbrushes uses a sensor in the handle to measure the applied pressure. A light ring at the top of the handle signals the pressure level in real-time: green indicates optimal pressure, red warns of too much pressure, and white (on some models) indicates too little pressure. This helps protect the gums from injury while ensuring an effective clean.
No, an electric toothbrush, even a highly advanced model like the Oral-B iO, cannot replace a professional dental cleaning at the dentist. Daily brushing at home is crucial for removing plaque and preventing dental diseases. However, a professional cleaning removes stubborn tartar and buildup in hard-to-reach areas that no toothbrush can access. A good electric toothbrush complements professional care and helps maintain the results of a professional cleaning for longer.
