Did you know that the world’s first toothbrush was a just a stick about the size of a pencil. One end was chewed into thus becoming softened and brush-like while the opposite end was pointed and used as a toothpick to clean food and debris from between the teeth. The twigs used were carefully chosen from aromatic trees that had the ability to clean and freshen the mouth. The earliest literature showing the use of these twigs is found in Chinese literature at around 1600 BC.
It has now evolved into the toothbrushes we see today. Nowadays toothbrushes can be broadly categorized into manual toothbrushes and electronic toothbrushes.
