Details

The C2 Optimal Plaque brush head with soft, flexible, stain-removal bristles helps whiten and polish your teeth; it also removes up to 700% better plaque than a manual toothbrush
Electric toothbrush for adults providing gentle yet effective cleaning: the Advanced Sonic Technology pulses fluid between teeth and along the gumline for even more effective oral care
Safe and gentle electric toothbrush with pressure sensor: if you apply too much pressure, the handle will pulse slightly, reminding you to ease off the pressure, protecting your teeth and gums
Optimize your routine: EasyStart for a gradual, gentle increase in brushing power, SmarTimer informing when you've reached 2 minutes, and QuadPacer to brush each section of a mouth for 30 seconds
Brush head replacement reminder tracks how often and how hard you brush, then notifies you when it's time to replace the brush head; dental professionals recommend changing your brush head regularly
Rechargeable toothbrush providing up to 14 days of regular brushing on a full charge
Philips Sonicare toothbrush from the #1 dental professional recommended sonic toothbrush brand worldwide²: benefit from Philips expertise to keep your teeth and gums in the best condition
The set includes: 1x Philips Sonicare 4100 Series electric toothbrush, 1x C2 Optimal Plaque brush head, 1x USB charger (power adaptor not included)
