On March 24, 1891, Toothpick was patented by Charles C. Freeman.
The toothpick is the oldest instrument for dental cleaning. It is known to predate the arrival of early modern humans. The skulls of Neanderthals, as well as Homo sapiens, have shown clear signs of having teeth that were picked with a tool.
Charles C Freeman patented a toothpick that is compressed and polished during manufacturing to produce a smooth toothpick.
