Answer:

Brushing too hard can erode the enamel on your teeth and cause gum recession. Many electric toothbrushes can solve this problem, too. They have pressure sensors that warn you if you're pressing too hard. That way, you can develop a proper touch that will remove plaque, but not damage your teeth and gums.

Explanation:

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
