Philips Sonicare 4100 Series Electric Toothbrush HX4046/41

Philips Sonicare 4100 Series (HX4046/41)

The 4100 Series sits in the middle of the Sonicare range. It adds a pressure sensor and a second brushing mode to the basics, and the box is generous: four W Optimal White brush heads and a travel case come with the brush. Philips rates the battery at up to 21 days of regular brushing.

What stands out

• Pressure sensor: if you press too hard, the handle gives gentle vibrations as a cue to ease off, which helps protect your gums.
• Two modes, two intensities: Gentle and Clean modes, each with two intensity levels.
• EasyStart: power builds up over your first 14 cleans to help you adjust from a manual brush.
• BrushPacer and SmarTimer: a prompt every 30 seconds and a signal at the two-minute mark.
• Four W Optimal White heads: a good supply, and Philips claims up to 5x more plaque removal than a manual brush. Treat that as a manufacturer claim.
• Travel case: included, along with the charger.

Who it suits

It suits people who want a pressure sensor and a decent stock of heads without paying for a premium model. Heavy-handed brushers will get the most from the sensor. It has no app connection or whitening-specific modes, so if those matter, look at the DiamondClean range.
