⚡ At a Glance
  • Cleaning Performance: Sonic bristle vibrations drive microbubbles between teeth for effective plaque disruption
  • Best for: Adults wanting easier daily whitening and gentler gum care

Sonic technology paired with the W2 Optimal White brush head targets surface stains and plaque. Built-in timers and a pressure sensor guide safer, more consistent brushing.


Visible stain reduction - with W2 Optimal White brush head and sonic action

Bristle vibrations create microbubbles that are driven deep between teeth, agitating and lifting surface stains. The W2 Optimal White brush head is shaped to target tooth surfaces for whitening with every session.

Whitening occurs as surface stains are loosened during normal two-minute routines, so users should notice a brighter smile without additional effort.

Gentler gum care - with a built-in pressure sensor and Sensitive mode

A pressure sensor detects excessive force and signals when brushing is too hard, while the Sensitive mode reduces brushing intensity for a softer clean. These elements work together to lower abrasion risk.

Reduced pressure alerts and a gentler mode make brushing more comfortable for sore or receding gums, helping users maintain regular habits without discomfort.

Consistent, complete brushing - with SmartTimer and 30-second QuadPacer

The SmartTimer counts a recommended two minutes while the QuadPacer prompts at 30-second intervals to move between mouth quadrants, encouraging even coverage across all teeth.

Following the guided timing helps achieve a thorough clean each time, and the included slim travel case plus USB charger keep the routine consistent away from home.
