Ultrasound vs Sonic: What's the Difference?


Dentists around the world recommend electric toothbrushes over manual toothbrushes because of their superior cleaning performance.

However, there are many different types of toothbrushes, which we will go into more detail in the article " Manual, rotary or sonic toothbrushes? ". However, one must also differentiate between sonic and ultrasonic toothbrushes. In the following we explain the main differences and what you have to consider.


sonic toothbrush
The sonic toothbrush has a so-called sonic converter, which generates vibrations. These are then transferred to the brush head and ensure that the bristles of the attachment vibrate. Our KOA sonic toothbrush has a powerful sonic transducer that can reach up to 37,500 vibrations per minute. Thus, teeth and interdental spaces are optimally cleaned.

But be careful: more does not mean better. Too high vibration frequencies from 40,000 vibrations per minute can become uncomfortable for one or the other and occasionally lead to irritation.

The condition of a sonic toothbrush is simple, very user friendly and extremely effective. There is also no need to use special toothpaste.

ultrasonic toothbrush
How an ultrasonic toothbrush works is a deterrent to many. The brush head is moved with up to 1.6 million vibrations per second. The correct application is done with a special toothpaste, which creates microbubbles on the teeth and cleans the teeth with the help of ultrasonic waves. The advantage here is that the spaces between the teeth are cleaned extremely well, so that you can almost save yourself the use of dental floss.

In terms of price, the ultrasonic toothbrush is significantly more expensive. The cheapest models only start at around €100.

our recommendation

First and foremost, we recommend our own KOA sonic toothbrush , which can be used without special toothpaste or application, and is also priced below the level of ultrasonic toothbrushes. There are also hardly any differences in terms of cleaning performance. Ultimately, you have to decide for yourself what is important to you when buying a toothbrush.
