Dentistry and dental hygiene have come quite a long way in the past several centuries. Most of us no longer rely upon chewing on stalks to keep our pearly whites fresh; and likewise, most dentists no longer offer whiskey as the anesthesia of choice before performing an extraction. This infographic by Fortis explains the evolution of the toothbrush. It contains information detailing the history of these dental hygiene tools dating all the way back to 3500 BCE and on to the present day. From the first toothbrush—the “chew stick,” made of frayed wood and used in Babylonia and Egypt—to Dr. West’s Miracle Tuft Toothbrush—the first made with synthetic nylon bristles, invented in 1938—to the smart toothbrush, invented in France in 2014—Fortis guides readers through the many advances in dental history, for which we can all be thankful.
