If ever there was a way to persuade your child to brush his or her teeth, turning it into a game was it. But forget the low-tech version you had to make up on the spot every night.

The Grush, $59/€50, is a gaming toothbrush, linking in with mobile games to gently persuade your children to spend more than 30 seconds brushing their teeth each night.

They can battle tooth monsters or take care of a virtual pet (though those of us who had Tamagotchis know how that one turns out). Another weapon in the parent arsenal.
