Effectively and gently clean kids' teeth with this Oral B Stages Power Electric Toothbrush featuring their favourite characters from Disney's Frozen. The toothbrush works in conjunction with the free Disney magic timer app, which help kids time how long they should be brushing for. The rotating brush head has a raised centre row to clean chewing surfaces where cavities tend to form and the ergonomic handle has been specially designed for children's small hands. Being battery operated, it's perfect for taking on holiday as well.
