Electric toothbrush bristles vibrate or rotate to help you remove plaque buildup from your teeth and gums. The vibration allows for more micro-movements every time you move your toothbrush across your teeth.
Are electric toothbrushes really better?
Electric toothbrushes clean teeth and gums much better than a manual toothbrush, according to the findings of a new study. Scientists found that people who use an electric toothbrush have healthier gums, less tooth decay and also keep their teeth for longer, compared with those who use a manual toothbrush.
Do electric toothbrushes actually spin?
Rotating-oscillating electric toothbrushes use a back-and-forth rotating motion to cup each tooth and can be as fast as up to 8,800 strokes per minute. Due to this rotating head, the brush can clean your teeth precisely and without unwanted pressure on your teeth.
