We had with the manual toothbrush often problems to properly get our son (2years) teeth clean because he has done it after a few seconds his mouth and had no desire to brush teeth. Since he is a big Mickey Mouse fan, we decided it the electric toothbrush from Oral B to buy the Mickey Mouse. We do not regret this purchase that brushing works since then great! We have brushing told him at the outset with the new toothbrush, he must leave open his mouth and could not bite, because it would otherwise make the Mickey Mouse "Ouch", and lo and behold, it works ;-) It makes him properly to make fun brushing his teeth, sometimes he will not want to stop! If we geputz him his teeth done, he must brush a little self. Then he tells the brush head with the Mickey Mouse bye and looking forward to it next time. The short melody is played, indicates when you can switch to the next half of the jaw, is pleased about our little every time very, even if it is only a very short melody.
