4100 Series Electric Sonic Toothbrush HX3681/33

Goodbye Manual Toothbrush. Hello Sonicare

The sonic technology combined with the brush head gently removes stains – for naturally whiter teeth with every brush.

• For white teeth with every brush: The electric Sonicare toothbrush with advanced sonic technology gently removes stains for naturally whiter teeth with every brush.
• The pressure sensor protects teeth and gums: The built-in pressure sensor automatically detects the pressure you apply, warns you and automatically reduces the vibrations of the toothbrush to protect your gums. The toothbrush emits a pulsating sound to reduce pressure. 7 out of 10 people found that this feature improved their brushing experience.
• This unique technology provides powerful yet gentle cleaning: Powerful bristle vibrations allow microbubbles to penetrate deep into your interdental spaces and distribute them along the gumline for a refreshing experience. Brushing for 2 minutes with this toothbrush is equivalent to brushing for two months with a manual toothbrush. 31,000 brush movements per minute gently clean your teeth, loosening and removing plaque for an exceptional daily cleaning experience.
• Optimize your brushing experience with the 2-minute timer and 4-quadrant timer: The 2-minute timer and 30-second 4-quadrant timer guide you through all areas in the recommended brushing time, ensuring a thorough cleaning.
• Always know when to replace the brush heads: All brush heads wear out over time, so you should always ensure that yours continues to clean ideally. The BrushSync technology remembers how long you've been using your brush head and how intensely you brush. The BrushSync reminder function on the handle and a short beep alert you when it's time to replace the brush head.
• Switch between 2 brushing modes: Clean and Sensitive: Switch between 2 brushing modes to make tooth brushing more comfortable.
• 14-day battery life: The battery life is up to 14 days, allowing you to go a long time without recharging.
• Consume less. Reuse more: At Philips, our goal is to reduce electronic waste. We achieve this, for example, by minimizing the number of adapters we sell. These products are delivered without a power adapter as we advocate for reducing electronic waste.
