Oral-B Pro Kids Spiderman Refills are designed to meet the specific needs of children's oral hygiene. Their round head, characteristic of Oral-B electric toothbrushes, is sized to fit children's mouths, allowing them to individually surround each tooth and effectively reach even the most difficult areas. The extra-soft bristles gently clean teeth and the gum line, providing a delicate and comfortable brushing experience. When used with a compatible Oral-B electric toothbrush, they help remove more plaque than a conventional manual toothbrush, promoting better oral health. Decorated with Marvel's Spider-Man characters, these refills encourage children to maintain a regular brushing routine. The six-refill pack offers an economical and practical solution, providing approximately 18 months of use, considering the recommended brush head replacement every three months. They are compatible with most Oral-B rechargeable electric toothbrushes for children and adults with a traditional attachment system, except for the Oral-B iO and Pulsonic models.
