Lets you know if you’re pressing too hard

Lets you know if you’re pressing too hard

Brushing too hard can damage your teeth and gums. To prevent this, your Philips Sonicare ProtectiveClean emits a gentle pulsing sound to remind you to ease off on the pressure.

Always know when to replace your brush heads

Always know when to replace your brush heads

All brush heads wear out over time. But our BrushSync technology tracks how long you've been using your brush head for, and how hard you've been brushing. When it's time to replace it, a light on your handle and a short beep will let you know. That way, you can be sure your brush head is doing a good job.

Brushes teeth.

Product performs as expected with several quirks, according to the information in the included user's Guide. A nice feature is the timed periods with a brief pause between brushing sessions so I know when to move to another quarter of my mouth. One quirk is there are 8 periods, not the expected four. The first four periods are the same length and the first four are longer than the second four, and those are of equal length. None of this behavior is described in the Manual. Please update the included Manuals to correspond to what the instrument does.
