Make brushing fun with Firefly's Clean N' Protect Sonic the Hedgehog Toothbrush. The buzz of the rotary power and soft bristles help encourage little ones to brush effectively. With stronger plaque-busting cleaning power than a manual children's toothbrush, little hands can remove plaque from their teeth. The kid-sized design makes it easier for children to clean those hard-to-reach areas of their mouth, while the massaging action of the premium soft bristles gently and effectively clean between teeth and along the gum line.
