- • Cleaning Performance: Up to 10x better plaque removal with the C3 Premium Plaque Defence brush head
- • Best for: Couples or households wanting two premium toothbrushes with guided routines
- • Not ideal for: Users who prefer a simple manual brush or single-handle setups
Sonic cleaning combined with the C3 Premium brush head targets plaque for whiter teeth. App connectivity and a pressure-sensing handle support personalised coaching and safer brushing.
Whiter teeth and reduced plaque – thanks to C3 Premium brush head
The C3 Premium Plaque Defence brush head is specified to remove up to 10x more plaque when used with sonic brushing action. Sonic vibrations move fluid between teeth and along the gumline to assist cleaning.
More effective plaque removal helps reduce staining and supports naturally whiter teeth with consistent use.
Personalised routines for better technique – with app connectivity and multiple modes
Four brushing modes and three intensity levels pair with the Philips Sonicare app for coaching and progress reports over a wireless connection. The app records sessions and highlights areas for improvement.
Guided sessions and adjustable intensities make it easier to match brushing to sensitivity and oral-care goals.
Gentle gum protection – thanks to an in-handle pressure sensor
A built-in pressure sensor detects excessive force and responds with a slight pulse from the handle as a reminder to ease off. The feedback helps prevent over-brushing.
Reduced risk of brushing damage keeps gums safer while maintaining effective cleaning.
