Our Review
The Sonicare 4100 is the entry point to Philips' sonic toothbrush ecosystem, and it punches well above its price. At around $43, you get 31,000 brush strokes per minute, a built-in pressure sensor, a 2-minute SmarTimer, a QuadPacer, and a 14-day rechargeable battery. The sonic action drives fluid between teeth and along the gumline for a thorough clean that feels noticeably different from oscillating brushes. It's Amazon's #1 best-selling sonic toothbrush for a reason — it does everything most people need without charging a premium for features they won't use.
