BrushSync technology
A microchip-enabled technology that detects and synchronizes the smart brush head with the smart handle. The smart handle and smart brush head pair is a powerful combination that enables Smart replacement reminders.

Safe and gentle
You can be sure of a safe brushing experience: our sonic technology is suitable for use with braces, fillings, crowns, and veneers, and helps prevent cavities and improve gum health.

BrushSync replacement reminder
All brush heads wear out over time. But our BrushSync technology tracks how long you've been using your brush head for, and how hard you've been brushing. When it's time to replace it, a light on your handle and a short beep will let you know. That way, you can be sure your brush head is doing a good job.

The only true sonic technology
Your Sonicare brush head and handle are the ultimate team. Enhancing our sonic technology, they give you unrivalled cleaning. High-speed vibrations in your toothbrush handle power up to 31,000 brush strokes per minute that whip up your toothpaste into plaque fighting bubbles, driving them deep between your teeth and along the gum line for exceptional cleaning.

Easy-start program
Starting something new can take getting used to. That's why our easy-start program gives you the option of a gradual, gentle increase in brushing power the first 14 times you use your new toothbrush

Too much pressure?
You may not notice if you’re brushing too hard, but your toothbrush will. If you start taking it out on your gums, the toothbrush will make a pulsing sound as a reminder to ease off on the pressure.

Helpful timers
Our QuadPacer lets you know when you've spent just the right amount of time cleaning each part of your mouth, while our Smartimer tells you when you've brushed for the recommended two minutes.
