The Oral-B iO Series 9 represents the high end of dental technology in India. After using this device for several weeks, I found that it moves away from the traditional mechanical feel of older electric brushes. Instead, it uses a frictionless magnetic drive system. This system sends energy directly to the bristle tips through micro-vibrations. At a price of 16,499 INR, it is a premium investment for oral health. My testing focused on whether the AI guidance and the various cleaning modes actually result in a cleaner mouth or if they are just flashy additions.
Key Takeaways
- The magnetic iO technology provides a quieter and smoother experience than previous oscillating models.
- The smart pressure sensor is highly effective at preventing gum damage by glowing red when you press too hard.
- AI tracking via the Oral-B app helps identify areas of the mouth that you usually skip.
- A full charge takes only 3 hours thanks to the magnetic quick charger.
- Users can see a visible reduction in plaque within the first week of consistent use.
Design and First Impressions
The Black variant of the iO Series 9 has a sleek, matte finish that feels premium in the hand. Unlike cheaper plastic models, this has a weight that suggests internal quality. The standout feature is the interactive colour display on the handle. When you pick up the brush, it greets you. It shows a timer while you brush and gives you a smiley face or a frown based on your performance.
The brush head design is still the classic round shape that Oral-B is known for, but the connection mechanism is different. It uses a magnetic system rather than a metal shaft. This change makes the brush significantly quieter. I noticed that it does not rattle your teeth like the older professional series might.
Understanding iO Technology and 3D Cleaning
The “iO” in the name stands for intelligent oscillations. To understand why this matters, you have to look at how it cleans. Most manual brushes rely on your hand speed. The iO 9 uses a 3D cleaning action. It oscillates and rotates to loosen plaque, while micro-vibrations pulsate to sweep it away.
During my tests, I noticed that the sticky film often felt on teeth after a meal disappeared more effectively with this brush than with a manual one. Oral-B claims it removes 100% more plaque and leads to 3X healthier gums in one week. While I cannot measure the exact percentage at home, my gums felt less irritated, and the “dentist clean” feeling lasted throughout the day.
The Role of AI and the Oral-B App
The AI capability is what sets the Series 9 apart from the Series 7 or 8. It uses sensors to track your brushing in 3D across 16 zones in your mouth. This includes the front, top, and back surfaces of your teeth.
When I used the app during a session, I could see a digital map of my mouth. As I brushed an area, the teeth on the screen turned from blue to white. This immediate feedback showed me that I often rush the back molars on the left side. Over a week, the app coached me to balance my time better. 8 out of 10 people reportedly become better brushers using this guidance, and I can see why. The visual proof of a missed spot is hard to ignore.
Smart Pressure Sensor for Gum Safety
One of the biggest risks with electric brushes is applying too much force, which can recede the gums. The iO Series 9 has the only sensor that tells you if you are brushing too soft.
- White/Blue Light: You are not pressing hard enough.
- Green Light: This is the “just right” pressure for an effective clean.
- Red Light: You are pressing too hard, and the brush will automatically reduce its speed to protect your gums.
This feature is the most practical part of the device. It teaches you to let the motor do the work instead of scrubbing.
Charging and Daily Maintenance
The magnetic charger is a small, puck-like base. The brush sits on top of it without any prongs. It reaches a full charge in about 3 hours. For someone who travels, the included Power2Go charging travel case is a big benefit. It allows you to charge the handle while it is stored in the case.
The 2-minute quadrant timer is built into the handle vibrations. Every 30 seconds, the brush stutters to tell you to move to the next section of your mouth. This ensures you spend the dentist-recommended time on your oral hygiene.

Verdict
The Oral-B iO Series 9 is a powerful tool for anyone serious about dental health. It successfully combines mechanical efficiency with digital coaching. While the price is steep, the technology inside justifies the cost for those who want to avoid expensive dental procedures later in life. The pressure sensor and the quiet magnetic drive are the highlights for me. It is likely the most capable toothbrush available in the Indian market today. If you can afford the initial cost and the ongoing price of refills, it provides a cleaning experience that manual brushes simply cannot match.
Frequently Asked Questions
Q1: Is the Oral-B iO Series 9 waterproof?
A1: Yes, the handle is waterproof and can be used in the shower, but you should not submerge it in water for long periods.
Q2: How often do I need to change the brush heads?
A2: Dentists recommend changing the brush head every three months or sooner if the bristles look frayed. The iO handle will also remind you when it is time to replace it.
Q3: Can multiple people use the same iO 9 handle?
A3: Yes, you can share the handle, but each person must use their own individual brush head for hygiene. However, the AI tracking might get confused if multiple people use one handle with a single app account.
Q4: Does it work without the app?
A4: Yes, the brush functions perfectly as a standalone device. The handle display shows your timer and pressure alerts even if your phone is not nearby.
Q5: Why is it better than a manual toothbrush?
A5: It provides many more strokes per minute and uses micro-vibrations to dislodge plaque that manual bristles cannot reach. The pressure sensor also ensures you do not damage your enamel.
