Sonicare DiamondClean Smart 9300 toothbrush

This Sonicare DiamondClean Smart 9300 electric toothbrush delivers up to 62000 brush movements per minute for a deep clean. It includes three premium brush heads for plaque control, gum care and whitening plus a glass charger and travel case. The rechargeable handle works on 110-220 V power.

Who this suits and who should look elsewhere

Buyers who want real-time pressure alerts and app-guided coaching will benefit from the Smart Sensor technology and Philips Sonicare app connection. Four brushing modes and three intensity levels let users personalise each session. Those who prefer a basic brush without connectivity or multiple modes should consider a simpler model.

62000 brush movements per minute

The sonic motor produces up to 62000 brush movements per minute, driving fluid between teeth and along the gum line. This speed underpins the claimed 20x plaque removal, 15x healthier gums and 100% stain reduction versus a manual toothbrush. If that movement rate matches your clinical goals, this is the right part.

Highlights

  • Up to 20x more plaque removed vs manual brushing
  • Up to 15x healthier gums with Premium Gum Care head
  • Up to 100% less stains using Premium White brush head
  • Real-time pressure sensor light ring protects teeth and gums
  • App connectivity gives personalised brushing guidance and coaching

Questions about this item

How loud is the HX9903/05 during its 62000 brush movements per minute when used all day?

The sonic motor runs at up to 62000 brush movements per minute; it produces a low hum typical of premium sonic toothbrushes and stays cool during extended daily use.

What must I already own to use the glass charger and app features on this DiamondClean Smart 9300?

You need a standard 110-220 V outlet for the glass charger and a compatible smartphone with the Philips Sonicare app installed for real-time feedback and coaching.

Will the Premium Plaque Control, Gum Care and White heads fit my older Sonicare handle?

The three included brush heads use the standard Sonicare click-on design, so they fit most existing Sonicare handles you may already keep.
