The Oral-B Kids 3+ toothbrush head provides a fun Spiderman theme for children while delivering a gentle yet effective clean recommended by dentists. It features extra-soft bristles and a small, round head designed specifically for kids and is compatible with all Oral-B Kids electric toothbrushes. This brush head offers a deeper clean than a manual toothbrush, helping to fight cavities. The kid-sized, extra-soft brush head uses Oral-B's softest bristles yet, acting as a cushion to prevent harshness while ensuring an excellent clean. The round head gently surrounds each tooth, allowing the brush to do the work. With various character options, children can personalize their toothbrush. Dentists recommend replacing brush heads every three months for optimal cleaning efficacy. The Oral-B Pro Kids brush head is guaranteed to fit Oral-B handles, excluding Pulsonic & iO models. Oral-B is the #1 brand recommended by dentists worldwide, with designs inspired by dentists to provide a gentle and effective clean for children at every stage of development.
