Every Oral-B iO looks premium, and prices across the range vary a lot, so which Oral-B iO to buy comes down to one question: what do you actually get by spending more? Every Oral-B iO shares the same superior plaque-removal technology. Higher models add more brushing guidance, more brushing modes and more convenience, not a different clean.
This guide covers what all Oral-B iO models have in common, three simple questions to find your match, a side-by-side Oral-B iO comparison and the right pick for different needs. Find your match in the Oral-B iO range.
What Every Oral-B iO Has in Common
Every Oral-B iO is built on the same core cleaning technology: a round brush head that combines oscillating-rotating movement with gentle micro-vibrations, a pressure sensor that warns when you brush too hard, and a 2-minute timer. Every iO brush head also fits every iO handle.
Moreover, Oral-B iO removes 2X more gumline plaque than a manual toothbrush, and the cleaning technology of Oral-B iO ranked #1 for plaque removal and gum care, based on a research ranking efficacy of toothbrush technologies published in 2026¹. Oral-B is the #1 Most Used Brand by Dentists worldwide.
The NHS recommends brushing for about 2 minutes, twice a day, with fluoride toothpaste, according to NHS guidance on keeping your teeth clean. Every iO timer helps you hit that target.
Three Questions to Find Your Match
The quickest way to choose an Oral-B iO is to answer three questions about how you brush and what you need day to day.
How much guidance do you want? Choose between a simple timer and pressure alert, an on-handle display, or real-time coaching through tracking and the Oral-B App.
Do you have specific needs? Sensitive gums, gum care or whitening goals are easier to support with extra brushing modes.
What else matters day to day? Think about travel, charging and budget.

New to Electric? Start Simple
The Oral-B iO2 and Oral-B iO3 are the best Oral-B iO choices for first-time electric users and anyone who wants a great clean without extra features. Both give you the same core iO clean, a pressure sensor and a 2-minute timer.
Oral-B iO2 is best for people making an easy, quiet first switch from a manual toothbrush. The Oral-B iO2 has a one-touch button, 3 intensity levels and an automatic pressure sensor that slows the brush and shows red if you press too hard.
Oral-B iO3 is best for people who want a simple brush with a few useful modes. The Oral-B iO3 adds 3 modes (Daily Clean, Sensitive and Whitening) and a LightRing timer.
Starting simple is a strong choice, not a compromise: the clean matches the top models.
Want More Feedback? The Mid-Range
The Oral-B iO5 and Oral-B iO6 suit people who want a little more guidance and personalisation. Both add an interactive on-handle display and extra brushing modes such as Sensitive and Gum Care.
Oral-B iO5 is best for people who want on-handle feedback without the full coaching features. The Oral-B iO5 adds an interactive display and a Smart Pressure Sensor.
Oral-B iO6 is best for people who want more personalisation, including a dedicated Gum Care mode. The Oral-B iO6 offers 5 modes, a Smart Pressure Sensor that glows red, white or green, and a display with brush head replacement reminders. Brushing recognition tracks 6 zones, and a travel case is included.
Want Full Coaching? iO9 and iO10
The Oral-B iO9 and Oral-B iO10 are for people who want full brushing guidance. Both use 3D Teeth Tracking to show which areas you brush and which you miss.
Oral-B iO9 is best for people who want to know exactly which areas they miss, care about gum health or travel often. The Oral-B iO9 tracks your brushing across the front, top and back surfaces of your teeth. It has an interactive colour display, 7 modes and a Smart Pressure Sensor. It connects to the Oral-B App, and its charging travel case keeps it powered on the go.
For most people who want full guidance, the iO9 offers the best balance of coaching, personalisation and convenience.
Oral-B iO10 is best for people who want live coaching at the sink. The Oral-B iO10 shares the iO9's 3D Teeth Tracking, colour display and 7 modes. It adds the iO Sense smart charger, which gives real-time coaching while you brush.
What You Gain by Moving Up the Range
Moving up the Oral-B iO range gives you more guidance, personalisation, feedback and convenience. The core clean stays the same superior technology at every level.
More guidance: from a timer and pressure alert to real-time tracking that shows which areas you have covered.
More personalisation: more brushing modes for specific needs, such as Sensitive, Gum Care and Whitening.
More feedback: an on-handle display on mid-range models, plus detailed insights through the Oral-B App.
More convenience: a travel case from the iO6, and a charging travel case on the iO9.
If you just want a superior clean, an entry model may be all you need. If you want help improving your habits, a higher model adds that support.
Don't Forget the Brush Head
All iO brush heads fit every iO handle, so you can choose a head based on your needs rather than your model. For example, Ultimate Clean suits an everyday deep clean, and Gentle Care suits sensitive gums.
The NHS advises replacing your brush head every 3 months, or sooner if the bristles look worn, according to its guidance on keeping your teeth clean. Browse iO replacement brush heads to find the right one.

FAQs
Do all Oral-B iO toothbrushes clean the same?
Yes. Every Oral-B iO uses the same round brush head with oscillating-rotating movement and gentle micro-vibrations, so the core clean is the same across the range. Higher models add more guidance, brushing modes and convenience features, such as 3D Teeth Tracking and a charging travel case, rather than a different clean.
What is the difference between the Oral-B iO models?
The main difference between Oral-B iO models is the level of brushing guidance. The iO2 and iO3 offer a timer and pressure sensor, the iO5 and iO6 add an interactive display and more modes, and the iO9 and iO10 add 3D Teeth Tracking. The iO10 also gives real-time coaching through its iO Sense smart charger.
Is the Oral-B iO9 worth it?
The Oral-B iO9 is worth it if you want full brushing guidance. 3D Teeth Tracking shows exactly which areas you miss, and 7 modes support needs such as gum care. Its charging travel case also makes the iO9 a practical choice for people who travel often.
Which Oral-B iO is best for sensitive gums?
For sensitive gums, choose an Oral-B iO with a Sensitive or Gum Care mode. The iO3 includes a Sensitive mode, while the iO6, iO9 and iO10 add a Gum Care mode. Pairing any iO handle with a Gentle Care brush head and avoiding too much pressure also helps.
Do I need the Oral-B App to use an Oral-B iO?
No. Every Oral-B iO works without the Oral-B App, with its timer, pressure sensor and modes built into the handle. The app is optional and adds detailed feedback, such as brushing coverage and habit tracking, on models that connect to it, including the iO9.
Do all iO brush heads fit every iO handle?
Yes. All Oral-B iO brush heads fit every iO handle, from the iO2 to the iO10. You can choose a head for your needs, such as Ultimate Clean or Gentle Care, and replace it every 3 months.
