Superior Cleaning Technology and Performance
The Philips Sonicare 4100 delivers exceptional cleaning performance through its advanced sonic technology. The brush generates up to 31,000 brush strokes per minute, creating dynamic fluid action that reaches deep between teeth and along the gum line. This powerful yet gentle cleaning action has been clinically proven to remove up to seven times more plaque than conventional manual toothbrushes.
The included C2 Optimal Plaque Control brush head features specially designed soft nylon bristles that conform to the contours of your teeth, ensuring thorough cleaning without causing irritation. Users can select between two intensity settings to customize their brushing experience according to their sensitivity levels and cleaning preferences.
Clinical studies have demonstrated that regular use of the Sonicare 4100 significantly improves gum health by reducing inflammation and bleeding. Additionally, the brush effectively removes surface stains from coffee, tea, and other substances, gradually restoring your teeth’s natural whiteness without harsh abrasives or chemicals.
Smart Features That Enhance Your Brushing Experience
The Philips Sonicare 4100 incorporates several intelligent features to optimize your oral care routine:
Pressure Sensor Protection
A built-in pressure sensor provides immediate feedback when you apply excessive force during brushing. This prevents the common problem of overly aggressive brushing that can damage gums and wear down tooth enamel over time.
Timing Features for Complete Cleaning
The integrated SmarTimer ensures you brush for the full two minutes recommended by dental professionals, while the QuadPacer feature signals when to move to a different quadrant of your mouth at 30-second intervals, promoting even and comprehensive cleaning throughout your mouth.
Gentle Introduction
For new users transitioning from manual toothbrushes, the easy-start program gradually increases power over the first 14 uses, allowing your mouth to adjust comfortably to the sonic cleaning experience.
The device features a simple one-button operation system and an ergonomic handle designed for a comfortable grip. A battery indicator light conveniently displays the charging status, eliminating guesswork about when a recharge is necessary.
Practical Design and Convenience Factors
The practical design of the Sonicare 4100 emphasizes convenience and usability. Its rechargeable lithium-ion battery provides up to two weeks of regular use on a single charge—ideal for both home use and travel. The compact dimensions of approximately 2.48 × 4.29 × 8.66 inches and lightweight construction (just 8.64 ounces) make it highly portable.
The toothbrush’s water-resistant handle allows safe use in the shower, adding flexibility to your daily routine. For travelers, the design eliminates the need to pack a bulky charging base for short trips, saving valuable space in toiletry bags.
This model maintains compatibility with all Philips Sonicare click-on brush heads, providing flexibility to switch to specialized heads for whitening, gum care, or other specific needs as your oral health priorities evolve.
