Philips Sonicare 4100 HX3681/23 Electric Toothbrush, White - Open Box

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.

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.
