"Systema Sonic Assist Brush 1" is an electric toothbrush (sound wave) of the type that sonic vibration assists hand brushing.

* The head thickness is 3mm, which is the same as the system toothbrush. The thin, compact head makes it easy to reach the periodontal pocket at the back of your mouth.
* The ultra-fine hair on the outside reaches between the teeth and the gap between the teeth and the back of the periodontal pocket to scrape off dirt. The ultra-fine hair in the center removes dirt from the tooth surface.
* Wave vibration (about 9000 times / minute) assists dirt removal.
* A bonus with 2 replacements.
