Children’s electric toothbrushes can generally start to be used around the age of 3. However, due to the poor control and weakness of the child, if the electric toothbrush keeps staying on 1-2 tooth surfaces for vibration, it can cause gum damage and enamel destruction, so the child should be taught to chatter evenly on each tooth. When applying electric toothbrushes for children, the toothbrush should generally be selected with a small head, soft bristles, and an integrated head and handle. It is recommended that before children use electric toothbrushes, they should first be taught to brush their teeth with ordinary toothbrushes, and get the brushing order, time and precautions right before brushing with electric toothbrushes in order to avoid artificially causing trauma and to better use children’s electric toothbrushes.
