Description:
3500 B.C.
Babylonians used chewing sticks to clean their teeth. They were careful to select twigs from aromatic trees that they believed would clean and freshen their mouth. They chewed on one end of the stick until it became soft like a brush, and kept the other end pointed to pick out food that got stuck between their teeth. These sticks were the size of a pencil.
