An educational DVD distributed to schools in the US state of South Dakota is zooming in on the fact that smoking might cause a need for emergency dentistry later in life.
The films, produced by the South Dakota State Medical Association Alliance, features an animated cigarette butt that comes to life and talks about the 4,000 chemicals that can be present in just one cigarette.
However, it also shows the teeth of smokers turning brown and eventually falling out.
It is hoped that the threat of impending emergency dentistry could be enough to put the children off starting smoking in the first place.
"They know it's bad for you but this helps it hit and let them see what it can do," said education officer Christine Bruxvoort.
According to the British Dental Health Foundation, smoking can lead to tooth staining, gum disease, tooth loss and even mouth or throat cancer.
