What the Sonicare 7100 delivers

The Sonicare HX7421/06 7100 is a rechargeable electric toothbrush built for daily oral care. It suits adults who want guided brushing and multiple intensity choices without a complicated setup. The handle pairs with the Sonicare app for real-time feedback and personalised tips. It is not for buyers who need a basic manual brush or a model without app connectivity.

Capacity and headroom: cleaning modes and battery

Twelve cleaning experiences come from four modes — Clean, Sensitive, Gum Health and Whitening — each with three intensity levels. The rechargeable battery provides up to 21 days of regular brushing on a single charge. A visual pressure sensor ring lights up when you press too hard, protecting gums during every session. The brush head reminder tracks actual wear and signals when replacement is due.

Practical limits of the charging interface

Charging uses a USB-A connection; the power adaptor is not included, so you must supply your own or use an existing USB port. The package includes a charging travel case and a charging stand for flexible top-ups. A 30-second BrushPacer and a 2-minute SmartTimer structure each routine. The app-dependent features require a compatible smartphone and an internet connection.

Questions about this item

Will the 7100 handle work with the brush heads I already own from an older Sonicare?

The handle accepts all click-on Sonicare brush heads, so your existing heads will fit and function normally.

How can I confirm the visual pressure sensor ring is active during brushing?

The ring at the base of the handle illuminates when you apply too much pressure; ease off until the light turns off to verify it is working.

Does the package include a USB power adaptor for the charging travel case and stand?

The box contains the 7100 handle, two G3 brush heads, a charging travel case, and a charging stand; a USB power adaptor is not included and must be purchased separately.
