With DiamondClean Smart, you get all the work done.

Our 3 intensity settings allow you to enhance your cleaning and our 4 modes cater for all your cleaning needs; Cleaning mode for excellent daily cleaning, White+ for stain removal, Deep Clean+ for an invigorating deep clean and Gum Health for a gentle clean along the gum line.

With intelligent brush tip recognition, you'll never get lost when it comes to replacing the brush head.

Your toothbrush tracks how long and firmly you've cleaned each brush head and will alert you when it's time for a replacement. You can also monitor the life of your brush heads using the Philips Sonicare app, and even order replacements so you never run out.

With an electric toothbrush, you let the brush do the work.

We've built a cleaning sensor into your handle to remind you to reduce scrubbing. That way you can improve your technique and get a gentler, more effective clean.
