How Do Electric Toothbrushes Work?

Electric toothbrushes have come a long way since their invention by Swiss doctor Philippe-Guy Woog in 1954 . Today, they primarily utilize two main technologies:

• Sonic Vibration: These brushes operate at high frequencies (typically over 30,000 movements per minute), creating microbubbles that penetrate between teeth and below the gumline. This "fluid dynamic" effect allows for thorough cleaning of hard-to-reach areas with gentle motion .

• Rotational-Oscillation: Featuring a round brush head that rotates back and forth, this technology provides an intensive, polishing action that effectively disrupts plaque biofilm. Some advanced models combine rotation with pulsations for what's termed 3D cleaning .
