Product information

Pros and cons

According to our electric toothbrush expert

With the SenseIQ technology, the toothbrush adjusts the brushing intensity, so you always use the right brushing mode for your teeth.
On the mouth map in the app, you can see exactly which teeth you're brushing well or should be brushed better.
You can easily charge your toothbrush on the go with the luxurious rechargeable travel case.
If you regularly use different brushing modes, the battery drains faster, so make sure to charge it in time.

Description

The Philips Sonicare DiamondClean Prestige 9900 HX9992/43 measures your brushing pressure, brushing movements, brushing time, and the areas you brush up to 100 times per second with SenseIQ. The toothbrush automatically adjusts its brushing mode and intensity accordingly, so you always use the right brushing mode for your teeth. For more feedback on your brushing behavior, connect the toothbrush to the smartphone app. The app shows your progress and gives you useful tips to learn to brush better. The toothbrush comes with 4 all-in-one brush attachments which also cleans hard-to-reach areas with its triangular ends and long bristles. As soon as the brush attachment needs to be replaced, you'll get a signal on the handle. This ensures you always brush your teeth thoroughly and hygienically.

Luxury toothbrush that guides you personally

Luxurious design and nice grip
User-friendly app
Nice guidance during brushing
Cleaning data not always visible

I think the Philips Sonicare Prestige HX9992/12 is a nice electric toothbrush. The toothbrush exudes luxury and the accompanying app makes it even more personal. However, you only see the brushing data when you are connected to the toothbrush.

Personal toothbrush Philips electric toothbrushes are not unfamiliar territory for me. I used to brush with the Philips Diamond Clean. So I'm used to the vibration intensity of the Philips electric toothbrushes. Before I started using the toothbrush, I had high hopes for this toothbrush. I was very curious about the accompanying app. The pairing went very quickly and I could immediately get started with brushing.

The toothbrush also features the new SenseIQ technology, which automatically adjusts the brushing mode as soon as you scrub your gums, for example. This prevents your gums from bleeding when you use a setting that is too hard. What I also like is that the app has many different functions. For example, the app guides you while brushing your teeth and allows you to set different brushing programs.

Luxury design and storage pouch The toothbrush is a real eye-catcher in the bathroom. It has a luxurious design and fits comfortably in the hand while brushing. The toothbrush is light in weight and slim in shape. Since I'm about to go on vacation, I find it very useful that it comes with a storage pouch. Just like the toothbrush, the storage case has a luxurious look. You can easily charge it in the storage pouch via the included USB cable. I like that, because that way you can leave the charging point at home when you spend the night somewhere else.

View data At the end of each week, I see an overview in which I receive feedback about my brushing behaviour. In this I see, for example, in which places I should brush better and where I should press softer with the brush. Handy, because that way you work towards a clean brushing result. What is a drawback, however, is that you only see the data when the toothbrush is not stored or is in the charging point. For example, it is not possible to show your dentist your brushing data.

Perfectly brushed teeth

Handy Sonicare app
SenseIQ
Vibrations to determine yourself

It takes some getting used to the strong vibration, but after a few brushings you're used to it. Easy to brush with the Sonicare app. This keeps track of where you brush and how well you brush the zone. If you put too much pressure on the brush, a light will burn at the bottom. Easy to carry in the luxurious pouch. My teeth feel smooth after brushing and by following the app you won't miss a tooth! In short, perfectly brushed teeth in 2 minutes!

Pricey but worth it, I notice the difference

I like the 'sonic vibration' better than other electric toothbrushes
Brushing app stimulating to brush well
Nice material
Pricey but worth it

I like the 'sonic vibration' better than other electric toothbrushes. Brushing juice (with model 'Prestige') stimulates me to brush extra well. Nice material, partly metal. Luxury travel case handy and nice extra. Happy with
