Toothbrush
Toothbrush
A toothbrush (/ˈtuːθ.brʌʃ/) is an oral hygiene instrument used to clean the teeth, gums, and tongue.
Etymology
The term "toothbrush" is derived from the Old English tōþ meaning "tooth" and brēost meaning "brush".
History
The first toothbrushes were twigs chewed on one end until they became soft and fibrous. The Ancient Egyptians and Babylonians are believed to have started using toothbrushes around 3500 to 3000 BC. The modern design of the toothbrush was not developed until the 17th century.
Types
There are two main types of toothbrushes: manual and electric. A manual toothbrush is a brush with a long handle and bristles on one end, while an electric toothbrush is a battery-powered toothbrush that moves the brush head to provide additional cleaning action.
Usage
Toothbrushes are used in conjunction with toothpaste to clean and maintain the health of teeth and gums. The American Dental Association recommends brushing teeth twice a day for two minutes each time.
