A funny video has emerged from the US of a 12-year-old girl using a remote-control car to pull her brother's tooth out.

The video, filmed near Denver, Colorado on November 30, shows the girl managing to remove the seven-year-old's tooth - which is attached to the toy by a stretch of dental floss - by sending the vehicle speeding forward.
