Toothbrush
- Aug 09, 2018 -

A toothbrush is a cleaning product, a handle-type brush, used to add toothpaste to the brush, and then repeatedly scrub the teeth in various parts. The earliest toothbrush comes from China. Human ancestors had the habit of gargling and brushing their teeth. In the king's Tomb of Sumeisur in 3000 BC, one of the earliest tools used to clean the mouth was found--a tooth stick that could last for two weeks. In ancient Greece and Rome, people used animal ashes as toothpowders to clean their mouths, and some primitive tribes cleaned their teeth with charcoal, salt water, fine sand and branches.
