Philips Sonicare 4100 Series Electric Toothbrush HX3681/33 for Daily Oral Care

The Sonicare electric toothbrush with advanced Sonic technology gently removes stains and helps make your teeth naturally whiter with every brushing.

The built-in pressure sensor automatically detects when you brush too hard, alerts you, and reduces the brush’s vibrations to protect your gums. The toothbrush emits a pulsing sound to remind you to ease the pressure. 7 out of 10 users found that this feature helped them become better brushers.

Powerful bristle vibrations create refreshing microbubbles that reach deep between the teeth and along the gumline. Just two minutes of brushing provides results comparable to two months of manual brushing. With 31,000 brush movements per minute, it gently cleans the teeth, removes plaque, and leaves a fresh, clean feeling.

The 2-minute Smartimer and 30-second QuadPacer guide you to brush for the recommended time in all areas of your mouth for a complete clean. Choose between two brushing modes — Clean or Sensitive — for the most comfortable brushing experience.

All brush heads wear out over time, so for the best results, you should keep track of your brush head’s condition. The BrushSync technology monitors how long and how intensively you’ve been using your brush head. When it’s time to replace it, the handle’s BrushSync replacement reminder and a short beep will notify you.

The rechargeable lithium-ion battery lasts up to 14 days, so you don’t need to charge the toothbrush frequently.
