Both manual and electric toothbrushes are effective for keeping your teeth and gums healthy.    Electric toothbrushes have oscillating rotating or vibrating heads. Tests show these toothbrushes are more effective at removing plaque.   Everyone can benefit from an electric brush. They are particularly useful for those with limited movements, such as disabled or elderly people.   As many now come with their mobile apps, they can also be better for children, who are motivated by the interactive nature of using an electric brush.
