By: Dr. David Rice

Before today, it was only possible for your patients to get a straight-from-the-dentist clean feel two times a year, but now with the biggest innovation from Oral-B, they can get a professional clean feel at home, every day!

Oral-B iO Rechargeable Electric Toothbrush

The Oral-B iO introduces a new era in brushing and is a monumental leap in innovative oral care technology that sets a new standard in the level of care and what you should expect from a toothbrush.

Oral-B has completely reimagined brushing and redesigned the brush from the inside out. 

The result? 

The new Oral-B iO combines the best-ever clinical performance with a superior user experience, making it the industry’s most advanced brushing product.

At-home care is more important than ever, with Oral-B iO, your patients can finally get a professional clean feel at home, every day, with a surprisingly enjoyable brushing experience.

Oral-B iO Features

Here is what the Oral-B iO has to offer:

1. Ultimate Clean Brush Head

Oral-B’s iconic round brush head is redesigned with reinforced, twisted bristles that reach every contour of a user’s tooth, with increased bristle density for a deeper clean. The brush head features a ‘Tuft-in-Tuft’ design, delivering a gentle, yet effective clean and interdental reach.

2. Linear Magnetic Drive System

Allows for energy to be delivered smoothly to the tips of the bristles, creating micro-vibrations which, when combined with oscillation rotation, create a smoother, more thorough clean (ie. Glides across the teeth).

3. Smart Pressure Sensor

An innovation that is the first of its kind to provide positive brushing feedback, identifying and guiding users to brush in the optimal pressure range. The Sensor features a variable-speed smart drive that adjusts amplitude to protect gums and enamel.

4. Interactive Display

Enables easy navigation through the brush features and personalization: welcoming greetings, choice of brushing modes, and reminders to change the brush head.

5. Visual Timer

The timer tracks each brushing session duration, so users know when they have brushed for the dentist-recommended two minutes. Smiley icons on the display let users know if they have achieved their goal.

6. Sleek Magnetic Charger

Provides a fast full charge in just ~three hours. The brush display provides an easy-to-read battery strength indicator.

7. iO App

Provides real-time individual tracking and feedback thanks to an AI platform powered by thousands of recorded brushing sessions. With a simple and intuitive user interface, AI Brushing Recognition technology recognizes where you are brushing and guides users to ensure 100% coverage to ensure a professional clean feel.
