Curaprox Hydrosonic Pro review: A powerful seven-mode, Swiss-made sonic brush

Curaprox Hydrosonic Pro: Two-minute review

The Curaprox Hydrosonic Pro toothbrush from Swiss company Curaden is a sonic brush that looks good, packs a fair bit of power and offers a comprehensive clean. Its octagonal shape and clinical whites and grays remind me of a satellite or space station, and the electric toothbrush itself is certainly a high-flier, and a contender for the title of “best electric toothbrush I’ve tried in 2025”, delivering a premium clean, albeit for a premium price.

The Curaprox is well-designed and functional. In the box you get the handset, a trio of brush heads equipped with soft Curen fibers, a plastic travel case, and a USB-A ‘nub’ type charging stand typical of many electric toothbrushes. Charging takes 10 hours, and the brush will last for 60 minutes on a full charge, which equates to around two weeks of use. As is the case with many toothbrushes, Curaden recommends that you don’t leave the Curaprox on charge constantly, and only charge it when the battery drops below 20%, as indicated by the LEDs running up the side of the handset.

Overall, it’s a pretty good package, although it would be nice at this price point if the case charged the brush too, so that you never have to worry about it on the go. I suppose that given its two-week battery life, the idea is that you should make sure the brush is fully charged before you go on your holidays.

The trio of brush heads comprise one for power cleaning, one for sensitive cleaning, and one for precision cleaning. The single brush head really allows you to get between teeth and gums, and I was very impressed: it’s bent backwards where the others have been bent forward, to account for the difference of use.

Curaprox says the Hydrosonic Pro has been designed for professional-level cleans at home (what electric toothbrush isn’t, according to the marketing people?) and the three brush heads coupled with the seven intensities mean you get a total of 21 bespoke cleaning modes. There’s also lots of helpful information in the manual, and it makes for quite interesting and educational reading when it comes to how to use the brush. I’d rather read the manual than have to follow the instructions in an app any day – I’ve got too many wellness apps on my phone as it is.

Replacement brush heads can be bought in packs of two of each kind from Curaprox, and, like the brush itself, they’re not cheap at $25.20 / £24.50 / AU$42.00 for a pack on Amazon.

That powerful motor can go from whisper quiet to annoyingly loud at the highest setting – over 65 decibels, according to the Decibel X app, which is louder than the 53 decibels I recorded for the similarly premium Philips Sonicare 7100. However, it is a good indication of how powerful the clean is, and during my testing I found myself using the single brush to clean across my gumline quite often – it’s a great design element that I’d like to see more manufacturers adopt.

Curaprox Hydrosonic Pro: Price and availability

• $199.99 / £190 / AU$299
• Replacement brush heads cost $25.20 / £24.50 / AU$42.00
• Not cheap, but high quality

The Curaprox Hydrosonic Pro costs $199.99 in the US, £190 in the UK and AU$299 in Australia, with replacement brush heads available in packs of two of the same head, so if you want spares of the power clean, sensitive or the single clean, you’ll need to pay twice. Crafty.

As you’ve probably gathered, while there are more expensive toothbrushes on the market this is certainly a premium option, and an ongoing investment in your oral health. It’s a very well-designed system, you could certainly do a lot worse – I’m of the opinion AI guidance and app-based rewards are almost never used on more expensive toothbrushes, and therefore are usually unnecessary – but the Curaprox Hydrosonic Pro represents the upper limit of what I think anyone should prepare to pay for an electric toothbrush.

How I tested

I used the Curaprox Hydrosonic Pro for one week. I charged it using the plug-in base, used all seven modes and all three brush heads, and used a decibel meter app to calculate how loud the brush was compared to other brushes on the market.
