3.2. Sonic Technology
Philips' unique Sonic Technology delivers approximately 31,000 ultra-high-speed brush strokes per minute with a wide amplitude. This creates a powerful 'Dynamic Cleaning Action' through fluid dynamics, effectively removing plaque from hard-to-reach interdental spaces and molars. This technology is supported by extensive clinical trials.

The brushing pressure applied by Sonicare is approximately half that of manual brushing. This allows for thorough cleaning while being gentle and safe for delicate gums.
