  • Our take on the Philips Sonicare Prestige 9900 HX9992

    The Sonicare Prestige 9900 is Philips' top-tier sonic toothbrush, with SenseIQ sensors that read pressure, motion and coverage and adjust intensity as you brush. It pairs with the Sonicare app over Bluetooth for guided coaching and progress reports, and it ships with a travel case and a charging station. It suits people who want feedback on their technique and will use the app; anyone who just wants a strong clean can get similar brushing from cheaper Sonicare models and skip the sensors. Owners like the clean and the coaching but many find it heavy and the app fussy.

    Questions and answers

    What is SenseIQ and does it change the brush's performance?
    SenseIQ uses sensors to detect pressure, motion and coverage, then adjusts intensity automatically. It mainly changes feedback and coaching rather than the basic sonic cleaning.
    How does the Prestige 9900 compare with the Sonicare DiamondClean?
    Both are premium sonics with app support. The Prestige 9900 adds SenseIQ sensing and a charging station; the DiamondClean line is lighter and has its own glass charger.
    Do I need the app to use it?
    No. The brush works on its own with its built-in modes and pressure sensor. The app adds tracking and coaching, and some owners skip it.
    What comes in the box?
    The handle, one brush head, a charging station and a travel case.
    Is it good for sensitive gums?
    The pressure sensor and lower-intensity modes help, and reviewers with sensitive gums report less irritation once they adjusted to the alerts.
