Tudi jaz imam Sonicare in jo moram zelo pohvalit. Glavna prednost je seveda "fluid dynamics"
Citat:
The brush head of your sonic toothbrush has been designed to vibrate at more than 30,000 brush strokes per minute.
This high-speed brushing action creates pressure waves and shear forces in the liquids that surround your teeth. It also generates minute bubbles that are forcefully propelled against surfaces where plaque has accumulated.
All combined, these fluid dynamics are able to disrupt dental plaque in those hard to reach areas such as between teeth and below the gum line.
This cleaning effect takes place at a distance of up to 4 millimeters (slightly more than 1/8th of an inch) beyond where the bristles of your Sonicare toothbrush actually touch.
