Why is the Oral B iO3 A Bestselling Toothbrush?

There are several reasons why the Oral-B iO3 is a popular favorite.

AI Brushing Technology:

The standout feature of the Oral-B iO3 electric toothbrush is its AI technology. It tracks your brushing habits and helps improve your cleaning technique with feedback if you miss any areas or apply excessive pressure.

The brush connects wirelessly to a Smartphone app. Sensors in the brush head monitor brushing duration and coverage. You’ll receive a score and personalized feedback. The pressure sensor also warns if you brush too hard.

Cleaning Performance:

The Oral-B iO3 toothbrush guarantees a thorough cleaning. Its design and engineering are backed by six years of research and development.

3 Cleaning Modes:

The Oral-B iO3 offers a choice of three brushing modes: Daily Clean, Whitening, and Sensitive. However, it does not include a gum massage mode. You’ll also get one Ultimate Clean brush head.

Timer and Pressure Sensor:

A built-in timer ensures that you’ll brush for the dentist-recommended 2 minutes. 30-second intervals let you shift from one quadrant to another. You can customize these settings through the app.

While some cheaper toothbrushes offer similar features and benefits, the Oral-B iO3 offers a combination of micro-vibration technology, gentle cleaning, quiet motor and decent battery life.

Together they make it an enjoyable and effective choice for most users.

Oral-B iO3 Review : Price

Although slightly more expensive than older Oral-B models, the iO3 electric toothbrush is well worth the price. This is because its AI-powered features do a great job of improving dental hygiene.

This is not a premium electric toothbrush and costs less than such devices. At the same time, it isn’t an entry-level model for users on a shoestring budget.

Given the features and benefits, almost every Oral-B iO3 review agrees that this is excellent value for money.

Is the Oral B iO3 Electric Toothbrush Right for You?

If you feel that

  • Your brushing habits and technique need improvement
  • You need superior plaque removal or suffer from gingivitis

  • You crave the latest advancements in toothbrush technology

… then the Oral-B iO3 model may be a great choice.

Oral B iO3 vs. Oral-B iO4 : Which is Better?

Oral-B iO3 review

When comparing the Oral B iO3 and iO4 electric toothbrush models, here are the key differences.

Feedback and Connectivity:

The Oral-B iO4 provides better feedback through Bluetooth connectivity to improve cleaning efficiency.

Cleaning Modes:

The iO4 offers enhanced cleaning modes, including the “Super Sensitive” mode specifically designed for sensitive teeth and gentle gum care. The iO3 does not have this functionality.

Traveling Case:

The Oral-B iO4 comes with a traveling case to store the brush handle and spare brush heads during travel. The iO3 does not include a traveling case.


The iO4 is slightly more expensive than the iO3, with a price difference of around twenty dollars.

In summary, the Oral B iO4 offers better feedback, additional cleaning modes for sensitive teeth, and a traveling case. So it’s better value for money as compared to the iO3.

However, take into account the price difference – and any available discounts – before deciding which to buy.

Oral B iO3 Review : Alternative Choices

If you’re interested in a high-end toothbrush with sonic technology, the Sonicare Prestige 9900 is a good choice. It has SenseIQ technology to adapt to your brushing in real-time.

If you’re on a tighter budget but still want a smart toothbrush, the Oral-B Genius X is an option. While its AI technology may not be as advanced as the Oral-B iO3 electric toothbrush, it still offers features like tracking and offers visual guidance.

If a smart toothbrush isn’t your priority, the Oral-B Pro 1000 provides all the essential features at a reasonable price. Alternatively, the Sonicare ProtectiveClean 4100 offers a minimalist design and reliable performance.

Oral B iO3 Review : Our Verdict

The Oral-B iO3 is a popular and powerful electric toothbrush featuring artificial intelligence (AI) to optimize your brushing.

It is affordably priced and offers good value for money. Although other models are more powerful or have more features, the Oral-B iO3 holds its own in a crowded market by being unique and special.

And any Oral-B iO3 review will affirm this.


  • Sleek brush handle design
  • Easy to keep clean
  • Pressure sensor indicates optimal brushing force
  • Quiet operation compared to other Oral-B models
  • Brush head replacement reminder
  • Approved by the American Dental Association (ADA)
