⚡ At a Glance
  • Cleaning Performance: Up to 3x more plaque removal along the gumline with the C1 ProResults brush head and 62,000 bristle movements per minute
  • Best for: Adults seeking a simple, effective upgrade from manual brushing
  • Not ideal for: Users who want multiple custom modes or advanced brushing programmes

High-frequency sonic action and a C1 ProResults brush head target plaque along the gumline. Built-in timing and pressure protection encourage safer, more compliant brushing.


Deeper Gumline Cleaning – With C1 ProResults brush head

Advanced Sonic Technology generates rapid bristle motion, reaching around 62,000 movements per minute, and pulses fluid between teeth and along the gumline. The C1 ProResults brush head is shaped to work with the sonic motion to dislodge plaque in the gumline area.

Achieves up to three times more plaque removal along the gumline for a noticeably cleaner feel after standard two-minute sessions.

Gentle on Sensitive Gums – Thanks to Pressure Sensor and Sonic Action

Pressure sensor detects excessive force and causes the handle to pulse slightly, signalling the need to ease off pressure. Sonic action cleans via fluid dynamics rather than heavy scrubbing, reducing mechanical abrasion on gums.

Protects against over-brushing and helps maintain gum health while still delivering an effective clean.

More Consistent Brushing Habits – With SmarTimer, QuadPacer and EasyStart

SmarTimer signals when the recommended two minutes are reached and QuadPacer divides the session into four equal intervals for balanced coverage. EasyStart gradually increases power during the first 14 uses to ease the transition from manual brushing.

Encourages full two-minute sessions and even quadrant coverage, making it easier to meet dentist-recommended brushing routines.
