Electric toothbrush

"I suppose Muggles need to protect themselves with all that machinery around. I almost lost an eye once, trying to figure out an 'electric toothbrush'."

- Myra Curio, discussing Muggle safety goggles

An electric toothbrush is an oral hygiene instrument powered by electricity, that makes rapid, bristle motions in order to clean teeth.

Myra Curio once remarked, when discussing about why Muggles needed things like safety goggles with Mathilda Grimblehawk, that she understood all the machinery Muggles surrounded themselves with was dangerous — a good example of this was when she almost hurt herself figuring out how an electric toothbrush worked.
