What the 3100 adds over the 1100 is a pressure sensor: the handle vibrates when you press too hard. Philips' catalog now lists this CTN under support status, but its US store still had it in stock at $39.96 when the data was captured. Philips does not publish its speed.

No owner discussion has been read for the Philips Sonicare 3100 yet. This section stays empty until there is something real to put in it.

How it moves

The elongated head vibrates side to side at high frequency; you hold it at the gumline and sweep along the teeth.

Where these figures come from

Every figure is the maker’s own, from its US product page, spec sheet or store, and the ADA listing comes from the ADA’s own site. A figure the maker does not publish is left out rather than estimated. The three-year cost, gum-safety and travel chips are worked out from those figures here.
