Philips Sonicare 2100 HX3651/12 sonic toothbrush

Unique sonic technology gives you efficient and gentle cleaning
Powerful vibrations of the bristles drive microbubbles into the interdental spaces and along the gumline for a refreshing feeling. In just 2 minutes you get the same effect as two months of cleaning with a manual toothbrush. 31,000 brush strokes per minute gently clean your teeth, remove plaque and ensure exceptional daily cleaning.
Up to 3x better plaque removal than with a manual toothbrush
It is clinically proven that the Sonicare electric toothbrush with its innovative sonic technology removes up to 3x more plaque than a manual toothbrush. It removes plaque from teeth and gums while protecting your gums.
Safe and gentle use
The sonic toothbrush offers thorough cleaning without unpleasant effects on teeth and gums. Gentle yet sufficiently strong sonic vibrations ensure exceptional cleanliness while being gentle on teeth and gums.
Optimise your teeth cleaning with the SmarTimer and QuadPacer functions
The 2-minute SmarTimer and the 30-second QuadPacer function help you brush for the recommended time and in all areas of your mouth, so you achieve a thorough clean.
The ergonomic design makes the brush easy to hold and use
Thanks to its slim, lightweight and ergonomic design, the brush is easy to hold, and you can reach perfectly clean teeth without any effort.
14-day battery life
The battery lasts up to 14 days, so you can go a long time without charging.
Easy-Start programme for an easy start
Our Easy-Start programme gives you the option to gradually and slightly increase cleaning power during the first 14 uses of your new toothbrush.
Reduce your consumption and reuse things
Power adapters may seem small, but the plastic from all of them together has a huge impact on the environment. Simply switching to a USB charger in our Philips Sonicare 1000–4000 range can save up to 189,210 kg of plastic every year.
