 | Outdated Product The introductory sonic electric toothbrush from the basic Sonicare 4100 Series line, released by the Philips brand in 2025.

The Philips Sonicare 4100 Series HX3689/43 electric toothbrush operates in a single daily cleaning mode with two intensity levels to choose between gentle and more powerful cleaning.
