Secondly, our children are interested in electric toothbrushes, which easily arouses their interest in brushing their teeth.
Electric toothbrushes also have some shortcomings, because when it is designed, for some functions, some functional reasons are taken care of. Relatively speaking, its brush head is larger. The other bristles are harder, and larger bristles have a disadvantage. When brushing the teeth, some of its crevices and deep pits and fissures cannot be brushed, and the brush is not clean. Too hard bristles can easily damage our teeth, and also easily damage our gums. As long as the manual toothbrush is used properly, it can actually have the effect of an electric toothbrush.
