Sonic unique technology brings you a powerful yet gentle clean
Powerful bristle vibrations drive microbubbles deep between your teeth and along your gum line for a refreshing experience. You will get two months' worth of manual brushing in just 2 minutes.** 31,000 brush strokes per minute gently clean your teeth, break up plaque and sweep it away for an exceptional daily clean.
Up to 3 x better plaque removal vs. a manual toothbrush*
The Sonic electric toothbrush with advanced sonic technology is clinically proven to remove plaque up to 3 x better* than a manual toothbrush. It removes plaque from your teeth and along the gum line while protecting your gums.
Safe and gentle to use
Sonic toothbrush provides you with a thorough clean without being harsh on your teeth and gums. Gentle yet powerful sonic vibrations provide an exceptional clean while being gentle on your teeth and gums.
Optimise your brushing with SmarTimer and Quadpacer
2 minute Smart Timer and 30 second Quadpacer guide you to brush for the recommended time in all areas of your mouth to ensure a complete clean.
14 day long-lasting battery life
Battery life lasts up to 14 days so you can go long periods without charging.
Easy-Start to ease the transition
Our Easy-Start Programme gives you the option of a gradual, gentle increase in brushing power the first 14 times you use your new toothbrush.
Ergonomic design makes the toothbrush easy to hold and use
Slim, lightweight and ergonomic design makes the toothbrush easy to hold and use so that you get an amazing clean without any strain.
Use less. Reuse more
Power adapters may seem small, but added together, their plastic makes a huge impact on the environment. By switching to a USB charger in our Philips Sonic 1000-4000 Series alone, we use up to 189,210 kg less plastic every year. That's powerful, right?

I've been using the Philips Sonicare 2100 Series for a while now, and I’m genuinely impressed with how clean my teeth feel after every use. The sonic technology gives a deep, refreshing clean without being too harsh on my gums. It’s lightweight, easy to hold, and the two-minute timer helps me brush just the right amount of time.
The battery life is great I can go over a week without recharging — and the USB charging option is super convenient for travel. It’s also much quieter than I expected, which is a nice bonus for early mornings.
Overall, it’s a simple, effective, and affordable electric toothbrush that delivers noticeable results. Perfect if you’re looking for a no-fuss upgrade from a manual brush.
