Pros and cons

According to our electric toothbrush expert

  • On the mouth map in the app, you can see exactly which teeth you're brushing well or should be brushed better.
  • Thanks to the vibrating handle and notifications in the app from the pressure and scrubbing sensors, you can prevent tooth damage.
  • You can easily take your toothbrush with you in the travel case.
  • If you regularly use different brushing modes, the battery drains, so make sure to charge it in time.

Description

With the Philips Sonicare DiamondClean 9000 HX9911/88 Aquamarine, you can effortlessly switch from a manual toothbrush to an electric toothbrush. The sonic brushing motion is a technique that's easy to master. Thanks to the 4 different brushing modes, you can easily adjust your brushing session to your needs. With the included Premium Plaque Defense brush attachment, you can clean your teeth even more thoroughly. That's because the brush hairs move according to the shape of your teeth. To improve your brushing technique, you get feedback in the accompanying Sonicare app. It's also connected to the pressure sensor and the timer of the toothbrush. On top of that, BrushSync notifies you when you need to replace the brush attachment. That's useful if your smile is your signature.

Nice electronic toothbrush

  • Long battery life
  • Pressure sensor
  • Nice sleek Design
  • Travel packaging very fragile

When using the Philips toothbrush for the first time, the experience was immediately great. By connecting to your phone you get a lot of information about your brushing performance. In the app you can find many tips and tricks on how to brush properly. Due to the sleek design and the cool color, the brush is one that stands out. What also stood out was the noise that is produced when brushing on the hardest setting. In addition, the tray in which you can store the brush when you travel is of cheap quality and fragile. The different brushing programs ensure that you can brush properly to the desired result that you want to achieve. Whether this is whitening teeth or just a thorough brushing. In the app you can also keep track of how many times your brush attachment remains good, as soon as it is worn, the app will indicate this and you can easily order new ones. The downside is that they are quite pricey. The brush contains a pressure sensor. As soon as you are brushing too hard, the brush will let you know by means of a. another vibration. After three weeks of brushing I am very satisfied and I also notice that there is more motivation to brush my teeth more often. Recommended if you also have to brush more from the dentist!

A quiet, versatile electric toothbrush you can use

  • Cleaning pressure sensor
  • Different brushing modes
  • Battery life
  • Pricey

I was allowed to try this toothbrush as part of a test procedure. I am particularly pleased with the results. You can select different brushing modes with this toothbrush, so that there is a suitable mode for everyone. I used the whitening mode and can see the difference after three weeks. Together with the handy tips via the app and the pressure sensor, I would definitely recommend this product. It is an expense, but then you also have something.
