Philips HX9917/88 Electric Toothbrush White

With DiamondClean Smart, you get all the work done. Our 3 intensity settings allow you to enhance your cleaning and our 4 modes cover all your cleaning needs; Cleaning Mode for superior daily cleaning, White+ for stain removal, Deep Clean+ for invigorating deep cleaning and Gum Health for gentle cleaning along the gum line.
Brush heads wear down over time and become less effective at removing plaque. With smart brush tip recognition, you'll never lose track of when to replace the brush head. Your toothbrush tracks how long and hard you've been brushing each brush head and will alert you when it's time to replace it. You can also monitor the life of your brush heads with the Philips Sonicare app and even order replacements so you're never out of stock.
With an electric toothbrush, you let the brush do the work. We've built a cleaning sensor into your handle to remind you to cut back on scrubbing. This way, you can improve your technique and get a gentler, more effective clean.
