Smart Sonic Toothbrush with App

The Sonicare DiamondClean Smart 9300 HX9903/65 is an electric toothbrush that connects to the Philips Sonicare app for personalized brushing guidance. It delivers up to 62000 brush movements per minute and includes two premium brush heads for plaque control and all-in-one care. The rose gold handle features a pressure sensor light ring that alerts you when brushing too hard. It suits adults who want connected feedback to improve daily oral hygiene habits.

Check Voltage and App Compatibility

Verify that your household supply falls within the 110-220 V range stated for the charging glass and stand. Ensure your smartphone can run the Philips Sonicare app to receive real-time coaching and brush head replacement reminders. The package includes a travel case, so confirm you have space to store the handle and heads when not in use. No additional accessories are required to begin brushing.

Glass Charging and Travel Ready

The charging glass and stand provide a stable, cable-free dock that doubles as a rinse glass for everyday convenience. A light ring on the handle flashes to warn against excess pressure, helping protect gums during each session. Brush head detection automatically selects the optimal mode and intensity for the attached head. The included travel case keeps the handle and two brush heads secure while on the move.
