During World War II, a German company, Auergesellschaft of Berlin, marketed a radioactive toothpaste, Doramad. On the back of the toothpaste tube it was stated that, ‘radioactive radiation increases the defenses of teeth and gums… cells are loaded with new life energy, the destroying effect of bacteria is hindered… it gently polishes the dental enamel and turns it white and shiny.’ The description failed to mention that the radiation could cause mutations and cancer in the mouths of the users and, when swallowed, many other organs of the body. The popularity of this toothpaste is unknown, likely because Germans were more concerned with surviving the war and “following orders” at the time.
