Pros and cons

According to our electric toothbrush expert

Thanks to the smart pressure sensor, you know exactly when you apply the right pressure.
With 3 brushing modes, you can easily adjust the brushing intensity to your teeth and gums.
With a 56-minute battery life, you can use the toothbrush for 2 weeks without charging in between.
The toothbrush has less brushing modes than the other Oral-B iO models.
You can't connect the toothbrush to your smartphone, so you don't get feedback on your brushing behavior.

Description

With the Oral-B iO 3N Black, you prevent damage to your teeth and gums. That's because the toothbrush has a smart pressure sensor. It indicates whether you're brushing too hard, soft, or just right with red, white, or green light. There are 3 different brushing modes. You can choose from a standard brushing mode, a setting for sensitive teeth, and a setting for whiter teeth. This way, you can adjust the brushing mode to your teeth and needs. After use, you place it on the charging dock. With a full battery, you can brush your teeth for 56 minutes.

Polishes thoroughly with the right pressure

3 brushing modes
Smart brushing pressure sensor
Replacement bulb for brush attachment
No display

Thanks to the smart 3-color pressure sensor, I always brush with the right pressure and get good results. I can also easily choose a brushing mode that suits my teeth. The only thing is, the toothbrush doesn't have a display to show the brushing mode.

Different Brushing Modes I take the toothbrush out of the box, and the matte color immediately catches my eye. This gives the toothbrush a luxurious look and looks great in my bathroom. I can choose from 3 different brushing modes. I always use the standard brushing mode, which works well for my teeth. The toothbrush also has a sensitive brushing mode and a whitening mode. The sensitive mode brushes more gently and is good if you have sensitive teeth, for example. If I want to brush more thoroughly, the whitening mode comes in handy. The only thing is, the toothbrush doesn't have a display to show the battery life and brushing mode. So I have to judge which mode I'm using by the brushing speed.

Brushing with the right pressure I also like that the toothbrush has a handy pressure sensor. The light ring under the brush uses three colors to indicate whether I'm brushing with the right pressure. If I'm brushing too gently, the light ring turns white. The light ring turns red if I'm applying too much pressure. This protects my teeth from excessive pressure. When the pressure is correct, the light ring turns green. The toothbrush also has a built-in 2-minute timer. Every 30 seconds, the brush gives a signal with a vibration. The brush head needs replacing after an average of 3 months. Normally, I always had to keep track of when my brush needed replacing. This toothbrush keeps track of this. A yellow light on the toothbrush turns on when I need to replace the brush.

Accessories I notice that the toothbrush has a long battery life. I don't have to charge it often. When it's empty, I simply place it on the included charging station. This way, I can charge it effortlessly and it looks neat in my bathroom. The toothbrush also comes with a handy brush head holder. When I go away for a weekend, I put the brush head in the holder. This way, I can keep my toothbrush neat and hygienic in my bag.

Review is 4,4 out of 10.

Battery delivered broken or much smaller than advertised

Battery lasts a maximum of 2-3 days

Works well, but the fact that the battery is empty after 2-3 days makes this electric toothbrush extremely annoying to use. Not 2 weeks, as advertised.

User-friendly and contributes to a good result

Good battery
Brushing pressure sensor so you know whether you are brushing properly

The design of the Oral-B io 3n looks nice. In addition, this toothbrush is also user-friendly and lightweight. While testing this toothbrush, I discovered that electric teeth brushing also provides better results. Thanks to the brushing pressure sensor, you immediately know whether you are brushing hard, too soft or well. Thanks to the good battery, you do not have to continuously charge this toothbrush.
