Quick Verdict:
Oral-B’s iO9 comes loaded with a magnetic motor, AI zone tracking, and a color display. The list tries to justify its ₹16,000 price tag. In India, I usually see it around ₹10,000 during Amazon or Flipkart sales, and that is the price point where you should actually grab it.
Should You Buy the Oral-B iO9?
If you want the best electric toothbrush in India, buy the iO9. The round-head brush really helps. Wait for a sale and buy it when the price drops near ₹10,000. If a great clean matters more than smart features, this is the right time to get it.
Skip the iO9 if you expect great things with AI zone tracking.
I have spent the last decade reviewing consumer technology, but nothing prepared me for brushing with a device marketed as AI-powered. The Oral-B iO Series 9 is the company’s most feature-loaded electric toothbrush, combining a magnetic drive motor, a color OLED display, Bluetooth connectivity, and 16-zone AI brushing analysis. My curiosity led me to test this product.
After a month of daily use, my conclusion is simple: the AI is not the reason to buy this toothbrush. The brushing experience is.
Right now, the iO9 is one of the most misunderstood products in the Indian personal care market. Many people buy it for the smart features and keep it for the clean. Let the smart features take a back seat in your verdict. Let’s look at the details.

Oral-B iO Series 9 Electric Toothbrush Review: Design and Build
The iO9 is the most visually refined electric toothbrush I’ve tested. Oral-B replaced the old glossy plastics with a matte, cylindrical handle. It feels balanced and stays put on a wet counter. The concave buttons are easy to find by touch, so you don’t have to look away from the mirror. The color OLED display is a real upgrade over icon-only screens. It shows all seven modes in plain text. You use physical buttons to navigate, not a touchscreen. That feels a bit old-school in 2026, but it works just fine.
The display lights up when you pick up the brush or set it down on a vibrating counter. That’s the motion sensor at work. It looks premium and makes the unboxing feel special. But it also quietly drains the battery all day, even when you’re not using the brush.
The biggest design issue for Indian homes is the gap around the magnetic brush head. That cavity traps water. In India’s humid bathrooms, it turns into a mould hotspot within weeks if you don’t rinse and dry it after every use. It’s not a deal-breaker, but you need to build a maintenance habit. Oral-B doesn’t warn you about this. To keep mould away, detach the brush head after each use, shake off excess water, wipe the attachment area with a towel or tissue, and leave the brush upright to air-dry before reassembling it.
After every use, I detach the brush head, shake off extra water from both the head and handle, and wipe the attachment area with a towel or tissue. Then I reassemble it and leave the brush standing upright to air dry. This simple habit keeps mould away and keeps the iO9 fresh for daily use.

The Motor
Oral-B’s magnetic iO drive is the biggest upgrade over older brushes. The old motors felt like jackhammers and got uncomfortable fast. The iO9 runs at 72dB in my tests. It’s much quieter, and the micro-vibrations feel smooth instead of harsh. The round brush head sits about 10 percent deeper than before. It wraps around each tooth instead of just brushing the surface. If you have crowded or overlapping teeth, which is common in India, this design really makes a difference.
The result? You get that just-left-the-dentist clean every time. That’s not an exaggeration. It’s the main reason to buy the iO9.
The Seven Cleaning Modes
The iO9 comes with Daily Clean, Whitening, Gum Care, Sensitive, Intense, Tongue Clean, and Super Sensitive modes. The color display makes switching quick. In reality, I used Daily Clean and Sensitive all month. For most people, the differences between modes are minor. The extra modes look good on the spec sheet but don’t matter much in daily use.
The Pressure Sensor
The 360-degree light ring is the most useful feature here. White means you’re not pressing hard enough, green is just right, and red means you’re pressing too hard. Within a week, the red light retrained my brushing without any app. This feedback actually improves your brushing over time. I always highlight this feature to anyone thinking about buying it, even if it’s not the only reason to get the brush.
The AI Zone Track
Oral-B calls the 16-zone Bluetooth tracking the GPS of oral health. After a month of testing, I found the comparison fits in one way. Like GPS in a crowded city, the signal bounces and often puts you in the wrong spot. That makes it hard to rely on tracking as a deciding factor. It should not shape your final verdict.
On paper, the tracking is detailed. It maps inner, outer, and biting surfaces across 16 zones. In practice, accuracy jumped around from session to session. Left-handed brushing, which many people use for the right side of the mouth, often didn’t register correctly. Living in an apartment with lots of Bluetooth signals made things worse.
Sometimes the app mapped my brushing to the wrong zone or missed it entirely. There’s also a lag in the on-screen feedback during live sessions. The Oral-B app is only in English right now, with no Indian language support, which could make it harder for some users.
The tracking works fine as a coaching tool for your first week. As a daily precision tool, it’s just not reliable. There’s a design flaw here. When you use the app for real-time zone tracking, the brush turns off its 30-second quadrant timer vibration. It assumes you’re watching the screen. I missed the vibration cue and ended up brushing unevenly.

Oral-B iO Series 9 Electric Toothbrush Review: Battery Life
Oral-B says you get 14 days of battery life. In my tests, with the display and motion sensor on, I got 12 days. The always-on display is why it dropped. The magnetic charging puck is excellent and easy to use. It charges the brush in three hours. Other premium brushes use USB-C or standard cables. For Indian travelers with universal adapters, that’s an extra hassle.
Review Verdict: Should You Buy the Oral-B iO Series 9 Electric?
Smartprix Rating (⭐): 8.5/10
The Oral-B iO Series 9 is the best electric toothbrush you can buy in India for the physical quality of its clean. The magnetic motor, round head geometry, and pressure coaching ring together deliver something cheaper brushes cannot match in the same way. If you have crowded teeth, a tendency to brush too hard, or want a dentist-clean feeling every morning, the iO9 earns its place on your bathroom shelf.

FAQ
Is the Oral-B iO9 worth ₹16,000 in India?
At full price, no, not for most buyers. The iO6 delivers a near-identical physical clean for roughly ₹9,000. The iO9’s premium buys you a color display and AI zone tracking that look impressive in demos but are inconsistent in daily use. Wait for a sale price around ₹10,000, and it becomes an easy recommendation.
How does the Oral-B iO9 compare to a regular manual toothbrush?
The iO9 outperforms a manual brush for most people. The round oscillating head removes more plaque from the gumline and tooth surfaces, and the pressure sensor prevents the overbrushing that causes gum recession over time. For someone stepping up from a manual brush, the improvement in their clean will be immediately noticeable.
Does the Oral-B iO9 work well in Indian bathrooms?
Yes, but it requires one specific maintenance habit. The gap around the magnetic brush head attachment point traps moisture and, in the high humidity typical of Indian bathrooms, can develop mould within weeks if you don’t thoroughly dry the brush after each use. Rinse the head, remove it, and dry both the head and the handle neck after every use.
What replacement brush heads does the Oral-B iO9 use?
The iO9 requires iO-specific brush heads, which are not interchangeable with standard Oral-B heads. They cost approximately ₹600 per head in India. Dentists recommend replacing brush heads every three months, which adds roughly ₹2,400 per year in running costs.
Is the Oral-B iO9 good for sensitive teeth?
Yes. Sensitive mode reduces motor intensity, and the pressure sensor ring actively prevents overbrushing, the most common cause of sensitivity. The magnetic motor’s smooth micro-vibration is also much gentler than older oscillating-rotation motors. Most users with sensitivity find it comfortable from the first use. Many dentists in India now recommend electric toothbrushes, especially models with pressure sensors and gentle modes like the iO9, for patients with sensitivity or gum issues. These features help promote healthier brushing habits and improve gum health compared to manual brushes.
Does the Oral-B iO app work reliably in India?
The app connects via Bluetooth and works reliably for basic features like mode tracking and brushing history. However, the 16-zone live tracking is inconsistent, especially in apartments with heavy wireless interference. The app is useful for setup and habit-building. It isn’t accurate enough to rely on for daily precision tracking.
