Poisoned tooth



A Poisoned tooth was a weapon of assassination during the time of the Faufreluches. It consisted of a false tooth with a cavity and false cap. The cavity was filled with poison gas. It was designed so that, when the bearer bit down hard on the cap and breathed out hard, the cap would break and the poison gas would be expelled into the immediate area.

It was designed to be virtually undetecable, short of close scrutiny.

Dr. Wellington Yueh planted such a tooth into the Duke Leto Atreides as a means for killing the Baron Vladimir Harkonnen after Yueh had delivered the Duke to the Baron through betrayal.

The tooth only partially worked. The Duke managed to kill the Baron's Captain of the Guard, his Mentat Piter de Vries, and several others, but not the Baron.
