2. Sonic vs. Rotating-Oscillating: Which Technology Is Better?
- Oscillating-Rotating (Oral-B): Small round head that spins back and forth to cup each tooth individually. Exceptional for removing tough tartar and staining.
- Sonic Technology (Philips Sonicare, Mi, Agaro): Oval vibrating head moving side to side at high sonic frequency. Generates fluid micro-bubbles that reach between teeth and beneath gumlines gently.
3. Who Benefits the Most from an Electric Toothbrush?
While everyone benefits, an electric toothbrush is a game-changer for:
- Orthodontic braces wearers (cleans around metal brackets effortlessly).
- Elderly individuals or those with arthritis/mobility limitations.
- Habitual ‘hard scrubbers’ suffering from gum recession.
- Children and teenagers who rush through their brushing routine.
