First toothbrush invented

The first toothbrush, resembling modern designs, was invented in China during the Tang Dynasty around 619-907 AD. It featured bristles made from the hair of animals, typically hogs, attached to a bamboo or bone handle. The concept evolved over the centuries, leading to the mass production of toothbrushes in the 20th century. The first mass-produced toothbrush was patented in the United States in 1938.
