Pros and cons

According to our electric toothbrush expert
  • With the 4 brushing modes, you can easily adjust the brushing intensity to your teeth and gums.
  • The 56-minute battery life allows you to use the toothbrush for 2 weeks without charging.
  • Thanks to the smart pressure sensor, you know exactly when you apply the right amount of pressure.
  • The included travel pouch isn't a charger, so you need to take a separate charging dock with you on holiday.
  • The toothbrush doesn't have as many brushing modes as the Oral-B iO 10, 9, and 8.

Polishes well, but battery issues.

Our expert review

Smart teeth brushing

  • 4 brushing modes
  • Long battery life
  • Healthier gums
  • Cleaning mode not visible

With this toothbrush you can take even better care of your teeth using different brushing modes and a brush head that contributes to healthier gums. You just don't see on your toothbrush which of the 4 brushing modes you use.

brushing modes
The toothbrush has 4 different brushing modes. By pressing the bottom button on the toothbrush, the toothbrush jumps to the next brushing mode. The modes are divided into brushing modes: standard, sensitive, extra sensitive and whiter teeth. It's just a shame that you don't see on the toothbrush which brushing mode it is set to.

During the first few brushings I used the standard brushing mode (Daily Clean). Especially at the beginning I had to get used to the Ultimate Clean brush head. This one felt harder than I was used to from an old-fashioned Oral-B Precision Clean brush head. Especially because the bristles also touch your gums a lot. Despite that, I really noticed that my gums were soon less irritated.

Although I normally use the Daily Clean mode, I also tested the sensitive mode a few times. It feels less hard than the normal position and is therefore pleasant for sensitive teeth and sensitive gums. The Whitening mode is really too hard for me compared to the two Sensitive modes. A solution for this would be the Oral-B iO Gentle Care brush heads. They have soft bristles on the outer edge and are therefore less painful for sensitive gums.

Pressure sensor and app
Thanks to the brushing pressure sensor, you can see exactly when you need to apply more or less pressure while brushing. In addition to the lights of the brush pressure sensor, the bottom button also gives an indication of when you need to replace your brush head. To improve your brushing technique even more, connect the toothbrush to the app. This monitors your brushing and then gives you feedback so that you can improve your brushing technique. You also see a timer and the brushing pressure sensor in the app. I find that this toothbrush, despite the bluetooth function, lasts a long time. After my old toothbrush, this is really a relief. I had to charge it every 5 days.

Beautiful appearance
I think the look of this toothbrush is very modern and chic. It really is a picture in your bathroom. The supplied travel case also looks neat. This allows you to conveniently store the toothbrush and take it with you in your suitcase without damaging it. When you turn on the toothbrush, the on and off button also lights up. This light also gives an indication when your toothbrush needs to be charged.

  • Much more powerful than my old Oral-b
  • Cleaning support via app
  • Battery
  • Privacy (especially with an account and link to other apps)

My old Oral-b was completely exhausted. A world of difference! The extensive connect options do raise questions. Does Oral-b or even Apple really need to know exactly when and how I polish my ivory guards?

Excellent toothbrush

  • Handy travel box

This excellent toothbrush has 4 convenient settings for different needs, with an accompanying app for brushing instructions. The handy storage box makes traveling easy. The built-in pressure sensor warns if you brush too hard, which turned out to be very useful during testing.
