Brush Up VR is a small virtual reality game from the studio Games That Work, released on Steam on 1 February 2017 to coincide with National Children's Dental Health Month in the United States. Its concept came from a family dentist, Dr Bob Jacobson, who wanted children to understand that brushing only what you can see in the mirror leaves much of the mouth dirty.

In the game you stand in a cartoon bathroom, pick up a giant toothbrush with your controller and brush the dirty teeth of a friendly monster. Music speeds up as time runs out, and at the end the game shows the dirt that is left, especially on the inside surfaces of the teeth, and gives a rating from zero to five stars. Each round lasts about a minute. The reviewer at The Ghost Howls liked the idea and the friendly graphics but found it too short and simple to hold attention for long.
