Teethbrusher 

A more advanced and less well-known version of the toothbrush. Brushes many teeth instead of just one. This word was never popularized.
Note: This is NOT the same as a regular toothbrush.

When I went for a sleepover at my friend's house, she had a spare teethbrusher for me to borrow.
