Key Features:
Choose from three modes
This toothbrush allows you to customize your brushing to your own needs, with a choice of three modes. Clean mode is standard for superior cleaning. White is the ideal mode for removing surface stains. And Gum Care mode adds an extra minute of reduced-power brushing, so you can gently massage your gums.
Philips Sonicare's advanced sonic technology
Philips Sonicare's advanced sonic technology pulses water between teeth, and its brush strokes break up plaque and sweep it away for an exceptional daily clean.
Lets you know if you’re pressing too hard
Brushing too hard can damage your teeth and gums. To prevent this, your Philips Sonicare ProtectiveClean emits a gentle pulsing sound to remind you to ease off on the pressure.
Encouragement to brush thoroughly
Need an electric toothbrush with a timer? 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.
Safe & gentle on sensitive areas, orthodontics & dental work
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.
Always know when to replace your brush heads
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.
Connects smart brush handle and smart brush heads
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.
Whitens teeth in just one week
Click on the W2 Optimal White brush head to remove surface stains and reveal a whiter smile. With its densely packed central stainremoval bristles, it's clinically proven to whiten teeth in just one week.
Makes traveling easier for you
Our premium travel case lets you store your toothbrush hygienically, while our compact charging base keeps you topped up when you’re on the go. You do get two weeks of regular use from a single full charge, but the charger's just the ticket for longer trips.

Why Buy?
A Smarter Clean That's Kinder to Your Teeth
If you want noticeably cleaner teeth without the guesswork, this Philips Sonicare is one of the simplest upgrades you can make to your daily routine.
The difference you'll feel after the first few uses is real — your teeth will feel that fresh-from-the-dentist clean far more often. It shifts significantly more plaque than brushing by hand, which means less buildup over time and healthier gums in the long run. The built-in pressure sensor is a standout — it quietly alerts you if you're pressing too hard, so you're protecting your enamel and gums without even thinking about it. You can also switch between three brushing modes depending on what your teeth need that day, whether that's a thorough clean, a gentle gum massage, or a bit of extra whitening.
It's a straightforward tool that fits easily into your morning and evening routine. The travel case and charger mean it's just as easy to keep up your routine on the road as it is at home — no excuses when you're away.

- You're prone to brushing too hard and want to protect your enamel
- You'd like options for whitening or gum care without separate tools
