Sonicare electric toothbrush with advanced Sonicare technology is clinically proven to remove up to 7x better plaque from your teeth and along the gum line while protecting your gums. 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. 2-minute SmarTimer and 30-second QuadPacer guide you to brush for the recommended time in all areas of your mouth to ensure a complete clean. 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. All brush heads wear out over time, so you'll want to keep an eye on yours to make sure 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 give you a heads-up when it's time to replace it. Switch between 2 intensity settings to make the brushing session comfortable for you. Battery life lasts up to 14 days so you can go long periods without charging. Power adapters may seem small, but added together, their plastics make a huge impact on the environment. By switching to a USB charger in our Philips Sonicare 1000-4000 Series alone, we can use up to 189,210 kg less plastic every 4 years.
