Sonicare 4100 electric toothbrush

The Sonicare 4100 is a rechargeable electric toothbrush that uses sonic pulses to remove up to seven times more plaque than a manual brush. It comes in black and includes one handle, one Optimal Plaque Control (C2) brush head, and a USB charger.

Ideal for first-time electric users.

The pressure sensor and two intensity settings protect sensitive gums, while the SmarTimer with QuadPacer guides the dentist-recommended two-minute routine. Buyers who want multiple cleaning modes, Bluetooth tracking, or a travel case should look at other models.

Two-week battery life per charge

A single charge lasts for up to two weeks of regular brushing, and a battery light indicator shows when it is time to recharge. The set includes the USB charging base so no extra accessories are required to start.

Questions about this item

Does the HX3681/24 handle come with a brush head and charger in the box?

Yes, the box includes one handle, one C2 Optimal Plaque Control brush head and one charger.

Will the C2 brush head fit my older Sonicare handle?

The C2 head uses the standard Sonicare click-on design, so it fits most earlier Sonicare handles.

How do I know the pressure sensor is active while I brush?

The sensor flashes a red light on the handle when you press too hard, signalling you to ease off.
