You'd think that if you had the ability to travel all of time and space, you wouldn't get bored. But if you think about it, we have tiny computers in our pockets, a vast internet to explore, and giant aluminum birds that can fly us all over the world and we still get bored from time to time. Boredom is what triggers creativity... or at least harebrained schemes.
The Doctor's boredom resulted in this Sonic Screwdriver Toothbrush. It's a little more sonic than your average toothbrush (but not as sonic as one of those fancy-schmancy toothbrushes). This vibrating toothbrush will clean your pearly whites after you dirty them eating a whole box of Jammy Dodgers. There's even a spare brush head so you can share your toothbrush with a friend!
