In 1815, Dr. Levi Spear Parmly, a New Orleans dentist, created the earliest iteration of the modern dental floss. It was a thin, waxen silk thread that he encouraged his patients use to clean between their teeth.
This thread was readily available everywhere because it was used in tailoring.
Four years later, Dr. Parmly published his dental book, “A Practical Guide to the Management of Teeth.” In the book, he recommended brushing twice a day and flossing once every day.
