you're still getting a great clean. Our BrushSync
technology tracks how long you've been using
your brush head for, and how hard you've been
brushing. The BrushSync replacement
reminder on your handle and a short beep
gives you a heads up when it's time to replace
it.
2 intensity settings
Switch between 2 intensity settings to make
the brushing session comfortable for you.
Long lasting battery life
Built-in pressure sensor automatically detects
pressure you apply, warns you, and reduces
the toothbrush vibrations automatically to help
protect your gums. The toothbrush will make
a pulsing sound as a reminder to ease off the
pressure. 7 out of 10 people found this feature
helped them become better brushers.
Powerful bristle vibrations drive microbubbles
deep between your teeth and along your gum
line for a refreshing experience. You will get
two month's worth of manual brushing in just
2 minutes.** 31000 brush strokes per minute
gently clean your teeth, break up plaque, and
sweep it away for an exceptional daily clean.
BrushSync replacement reminder
All brush heads wear out over time, so you'll
want to keep an eye on yours to make sure
Battery life lasts up to 14 days so you can go
long periods without charging.
Goodbye adapter. Hello USB.
Power adapters may seem small, but added
t
ogether, their plastics make a huge impact on
the environment. By switching to USB charger
in our Philips Sonicare 1000-4000 Series alone,
we can use up to 189,210 kg less plastic every
4 years. That's powerful, right?
