Hydrosonic and Tube

Here's what we offer, plain and simple:

The Hydrosonic Black Is White is a high-performance sonic toothbrush. Thanks to its hydrodynamic effect, it even cleans the places where bristles can't reach – between the teeth, for example.

Used in combination with the Black Is White toothpaste, this brush ensures perfect oral hygiene and gleaming white teeth, with no harmful side effects. In fact, Black Is White doesn't contain any ingredients that could pose a risk to health; it simply cleans and protects your teeth and mouth all at once.

The Hydrosonic Black Is White and Black Is White whitening toothpaste: an unbeatable team.

It's so easy!

Form follows function. Outstanding technology, easy handling, stylish design.

Hydrosonic Power


The Hydrosonic Black Is White comes with an extra-powerful battery, so you can clean your teeth all week long without having to charge it up – that's over 40 minutes of brushing time at full power!

You can tell when the device needs charging when the bottom LED lights up for one minute, or when it simply stops responding.

To charge the device, all you have to do is connect one end of the US charging cable to the XS charging dock and the other end to the USD plug or to a laptop or mobile phone adaptor.

Black is White Toothpaste


The gentle way to whiten your teeth: no bleaching agents, no abrasives. Black Is White toothpaste even boosts your oral health.


Activated carbon makes the toothpaste pitch black, but keeps your teeth pearly white.


"Black Is White" covers the teeth with a protective film made of hydroxyapatite, white remineralises the enamel and even tackles any cavities that are starting to emerge.
