Kids can use regular Sonicare toothbrushes. However, often the size is too big for children to use the toothbrush in an effective way. Therefore, it is important that when a child uses a regular Sonicare toothbrush, they have been instructed on how to properly use the toothbrush. It is recommended for children to use an electric toothbrush that is specially designed for children. With a specific toothbrush for children it is easier to teach your child proper brushing habits.
