What is the main difference between a sonic toothbrush and a rotating toothbrush?
A sonic toothbrush uses high-frequency vibrations and fluid dynamics to provide a gentler, deeper clean, while a rotating toothbrush relies on mechanical rotation to physically scrub away plaque with more friction.
Do I have to cycle through all 5 modes before I can turn this sonic toothbrush off?
NO. You can turn it off at any time by pressing and holding the button for 1-2 seconds - there's no need to go through all 5 modes.
Why can't I switch brushing modes?
In the latest version, modes can only be switched within 3 seconds after turning on - to avoid accidental touches. After 3 seconds, pressing the button only turns the toothbrush off. New and old versions ship randomly until the old version sells out.
