Sonicare Fluid Action
Philips Sonicare toothbrushes clean gently yet effectively and care for your teeth and gums with 62,000 bristle movements per minute. Sonicare Fluid Action supports the bristles to clean by driving fluid deep between teeth and along the gumline.

Keep brushing your best with the brush head replacement reminder
Did you know brush heads become less effective after three months? Dental professionals recommend changing your brush head regularly, so that's why Philips Sonicare toothbrushes have a brush head replacement reminder. It tracks how often and how hard you brush, then reminds you to replace your brush head once it's time for a new one.
14 days of regular brushing
Experience up to 14 days of regular brushing after a single charge, bringing a new level of convenience to your brushing routine.
