Pressure Sensing and a Denser Brush Head

The Philips Sonicare 4100 pairs 31,000 brush strokes per minute with a C2 Optimal Plaque Control head, the combination that lifts this tier to up to seven times more plaque removed than a manual brush. A built-in pressure sensor vibrates the handle when you press too hard.

Two intensity settings let you ease off on sensitive days or push for a deeper clean, and a BrushSync light tells you when the head is worn. The lithium-ion battery runs about fourteen days of twice-daily brushing, so it travels for a fortnight without a charger.

Key Features

C2 Optimal Plaque Control head - the denser head that drives the 7x plaque figure
Built-in pressure sensor - the handle vibrates when you press too hard, protecting gums
BrushSync reminder - an amber light tells you when the head is worn out
2 intensity settings - lower for sensitive days, higher for a deeper clean
31,000 brush strokes per minute - drives fluid between teeth and along the gumline
SmarTimer and QuadPacer - a 2-minute timer with 30-second quadrant prompts
14-day lithium-ion battery - a fortnight of twice-daily brushing per charge
Easy-Start ramp-up - power builds over the first 14 uses for a gentle switch

Open Box Condition

This this toothbrush has been opened and inspected, fully tested and verified working. Original packaging and all in-box accessories are included. May show minimal signs of handling.

Every electric toothbrush we list is checked in our Toronto shop before it goes on the shelf, so what arrives is what the page describes. This Philips unit is stocked and ships from within Canada, which keeps delivery short and avoids surprise customs charges at the door. If you are weighing it against another model, our team takes questions by phone or email and can tell you exactly what is in the box before you commit. Orders placed on business days leave the same day wherever stock allows, and in-store pickup is available in Toronto if you would rather collect it yourself.
