They should exist, people who brush their teeth without a smartphone.

We're not talking about watching the latest Tiktok videos while cleaning, but using the app to check whether all tooth surfaces are cleaned evenly.

This has been possible for years with the Oral-B IO from Procter & Gamble, using only the sensor data from the brush handle.

It is recognized in real time which tooth segment it is currently its turn and even a distinction is made as to whether the inside or outside or the occlusal surface is being cleaned.

The app then calculates which segment and which area still needs special attention and displays this.

The accuracy of the recognition is amazing.

Those who shy away from reaching for the iPhone when it comes to brushing their teeth can now also purchase the IO with a new charging station.

The Series 10 comes with IO Sense, a loading puck that visualizes with six large LEDs on the top which areas of the teeth have already been sufficiently cleaned and which should be reworked.

During cleaning, the light fades from blue to white.

A digital display on the front shows the brushing time and the pressure control causes the LEDs to flash red if too much pressure is being applied to the teeth.

A bimodal pressure sensor is used.

In contrast to other toothbrushes, not only too much pressure on the teeth is pointed out, but also too little.

An illuminated ring below the brush head also shows the correct pressure, the changing color of which can be seen clearly in the bathroom mirror.

As usual, you can choose from various cleaning programs using the OLED display of the brush in conjunction with the menu button.

The new charging puck charges the toothbrush, connects via Bluetooth to the smartphone app and even to the home WLAN.

But inductive charging of other devices does not work, the puck is also significantly larger than that of the previous models without LED, and despite all EU requirements, no USB-C connection for the power supply is used here, but a proprietary format.

The brush runs smoother and quieter

If you want to continue using the cleaning control in the app with the new Series 10, you can do so too.

The fact that you can collect medals for good cleaning in the app and be reminded to replace the brush heads is a bit of a gimmick, and you are also reminded to use dental floss and mouthwash.

The new model variant continues the most important advance of the IO.

In contrast to other electric toothbrushes, there is no mechanical drive for the brush, but a magnetic one, which transfers the energy more efficiently and evenly to the brush head.

The movement is rotating and oscillating at 145 hertz.

The brush runs smoother and quieter, and the brush heads have twisted tips that allow for better cleaning between teeth.

The Series 10 battery lasts for several days without recharging on the puck.

When traveling, you can use the supplied case and the power adapter to recharge the battery, and a USB-C port could also make for lighter luggage here.

The Series 10 went onto the market with an official retail price that is hard to believe: 600 euros.

The street price is currently around 350 euros.

A cheap IO model variant is already available for 130 euros, and the brush heads cost around 7.50 euros.
