Children's electric toothbrushes are usually suitable for ages 3 and above. At this age, most children already have some coordination and brushing skills and can start trying to use an electric toothbrush. However, even with an electric toothbrush, parents still need supervision and guidance to ensure that their children are brushing correctly and not using excessive force or doing it incorrectly.

For children under 3 years old, it is recommended to use a manual toothbrush because their coordination and brushing skills may not be mature enough, and using an electric toothbrush may be risky. As your child grows and shows an interest in brushing their teeth, consider transitioning to a child-friendly electric toothbrush.
Children"s electric toothbrushes typically have smaller brush heads, soft bristles, and are designed to fit the size of a child's mouth to ensure safety and comfort. When choosing a children's electric toothbrush, pay attention to the product's age recommendations and design features to ensure it meets your child's oral needs and growth stage. At the same time, always brush teeth with your children and educate them on correct brushing methods and habits.
