Philips HX2421 Smart Sonic Electric Toothbrush: Up to 30,000 brush strokes/min
This Philips electric toothbrush is designed for anyone seeking a more effective clean than manual brushing provides. It's perfect for busy professionals who want to maintain dental health without spending extra time at the sink.
While many focus on the power of electric toothbrushes, this model emphasizes gentle precision. The Sensitive mode offers a comfortable experience for those with sensitive gums, while still delivering up to 30,000 brush strokes per minute. You'll notice the slim ergonomic handle fits naturally in your hand, making it easy to reach back teeth without strain.
The rechargeable battery lasts up to two weeks on a single charge, so you can travel without the charger. The easy click-on brush heads simplify replacement, and the included Gentle Clean standard head helps reduce cavities effectively. Compatible with standard brush head systems, it works seamlessly in any bathroom routine.
