Sonicare 4100 Series Electric Sonic Toothbrush HX3689/42

Goodbye, manual toothbrush. Hello, Sonicare!
The sonic technology combined with the brush head gently removes stains – for naturally white teeth with every brush.

For brilliantly white teeth with every use
The electric Sonicare toothbrush with advanced sonic technology gently removes stains for naturally whiter teeth with every brushing session.

Protection for teeth and gums thanks to pressure control
The integrated pressure control automatically detects how much pressure you are applying, warns you, and reduces the vibrations of the toothbrush to protect your gums. It emits a pulsing sound and reduces the vibration. 7 out of 10 people found that this feature improved their brushing experience.

Enhance your brushing experience with the 2-minute timer and 4-quadrant timer
The 2-minute timer and 30-second 4-quadrant timer guide you through all areas of your teeth in the recommended brushing time for a thorough clean.

Switch between two intensity levels
Adjust the intensity and switch between two levels to make your brushing experience more comfortable.

Gentle and effective thanks to unique technology
Powerful brush vibrations allow microbubbles to penetrate deep into the gaps between teeth and distribute them along the gums for a refreshing feel. Two minutes of brushing with this toothbrush is equivalent to two months of brushing with a manual toothbrush.** With 31,000 brush head movements per minute, plaque is gently loosened and removed – for an exceptional cleaning experience every day.

Always know when to replace your brush head
Thanks to BrushSync technology, you always know exactly when it's time to replace the brush head. It keeps track of how long you've been using your brush head and how intensely you've been brushing. The reminder feature and a tone on the handle alert you when it's time to replace the brush head.

14 days of battery life
The battery lasts up to 14 days, so you can go a long time without recharging.
