"electric toothbrush"的定义和意义

What is an "electric toothbrush"?

An electric toothbrush is a motorized oral care device that provides automated brushing movements for effective dental hygiene. It features a rotating or vibrating brush head that moves rapidly to clean teeth and gums. The oscillating or sonic motions of the bristles help remove plaque, tartar, and food particles more efficiently than manual brushing. Electric toothbrushes often come with various cleaning modes, such as daily cleaning, sensitive mode, and gum care, allowing users to customize their brushing experience. The built-in timers and pressure sensors in some models further enhance brushing technique and ensure optimal oral health.
