A rotating electric toothbrush uses a circular motion to effectively remove plaque and debris, especially along the gum line. It typically includes timers and modes, making brushing more efficient, particularly for those with limited dexterity.
A sonic electric toothbrush vibrates at high speeds (30,000–40,000 strokes/min) to remove plaque gently. The vibrations help clean hard-to-reach areas, promoting gum health with less pressure and a quieter operation.
