Philips' flagship. SenseIQ, Philips says, changes the brushing automatically as both pressure and motion change (the 7100's automatic power adjustment is the nearest thing below it), and the Prestige USB travel case charges the handle. It is also the priciest brush in this catalog, and ships with a single A3 head.

Pressure sensor and ADA Seal

Multi-signal pressure sensor. Philips Sonicare's description: SenseIQ adjusts brushing automatically based on pressure and motion; ring lights purple with vibration.

No ADA Seal listing found for this model on the ADA’s own product search. That is not a failed test: the Seal is voluntary and makers apply for it product by product.

These are facts about features and listings, not a statement that the brush prevents or treats anything. What a pressure sensor does · What the ADA Seal means

Three years of ownership

Handle: $380
Heads (11 × $6.66): $73.26
Three-year total: ~$453

12 heads over 36 months at Philips Sonicare's stated 3-month interval, less 1 head in the box. Head price: Sonicare SimplyClean 6-pack (HX6016/77), $39.96 on usa.philips.com. How this is worked out

What the extra money buys: Same 62,000 brush movements / min and a pressure sensor as the Philips Sonicare Series 5700; the extra $300 buys 3 more modes, app tracking, a multi-signal pressure sensor, a charging travel case and a charging stand. See the Philips Sonicare Series 5700.

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.
