A video of the act which shows Robert Abercrombie in Florida revving up the car before hitting the accelerator as the string dangles from his son's mouth has gone viral on the internet.
Fortunately, the amateur dentistry produced results and the kid's head barely jerked as the tooth was whisked away.
"It came out!" said the grinning boy in the video, 'Sky News' reported.
Abercrombie, a professional wrestler who goes by the name Rob Venomous, said he has been surprised by the video's popularity.
