During World War II our soldiers were required to brush their teeth daily, something most Americans did not do. At the same time the Dupont de Nemours company introduced the first toothbrush with nylon bristles, Dr. West’s Miracle-Tuft Toothbrush. Their ad campaign “Your American Duty…” encouraged all Americans to brush daily. When the soldiers came home, they kept up this very excellent routine, and their families joined in. Today, we recommend brushing twice a day and flossing daily – maybe not your American duty but certainly a great habit!
