Oh those crazy Germans. Who else would market radioactive toothpaste. Doramad Radioaktive Zahncreme was produced during World War II by Auergesellschaft of Berlin.
“Its radioactive radiation increases the defenses of teeth and gums. The cells are loaded with new life energy, the bacteria are hindered in their destroying effect. This explains the excellent prophylaxis and healing process with gingival diseases. It gently polishes the dental enamel so it turns white and shiny. Prevents dental calculus. Wonderful lather and a new, pleasant, mild and refreshing taste,” states the archive at Oak Ridge Associated Universities.
Mel Brooks couldn’t have made this up. Die Verrückten Deutschen!
