More plaque removed around the gumline – Thanks to C1 ProResults brush head

The C1 ProResults brush head targets the gumline and, together with Advanced Sonic Technology, pulses fluid between teeth. The sonic action reaches areas that manual brushing often misses, using around 62,000 bristle movements per minute.

Improved plaque removal helps reduce staining and supports healthier-looking gums with regular use.

Gentle gum protection – With pressure sensor and EasyStart

Pressure sensor triggers a slight pulsing of the handle when excess pressure is applied, while EasyStart increases brushing intensity gradually across early uses. These features reduce the risk of overbrushing during the adaptation period.

Less risk of gum abrasion and an easier transition for users new to sonic brushing.

Consistent two-minute clean – With SmarTimer and QuadPacer

SmarTimer signals when two minutes of brushing are complete and QuadPacer divides the routine into four 30-second intervals for even coverage. Timed cues encourage thorough cleaning of all mouth quadrants.

Helps achieve dentist-recommended brushing time and ensures balanced cleaning across the mouth.
