An Electric Toothbrush is a type of toothbrush that is powered by electricity to move the brush head, providing superior plaque removal compared to a manual toothbrush.
Pronunciation
Electric Toothbrush: /ɪˈlɛktrɪk ˈtuːθbrʌʃ/
Etymology
The term "Electric Toothbrush" is derived from the words "electric", which comes from the Greek word "ēlektron" meaning amber, and "toothbrush", which is a compound of the words "tooth" and "brush". The first electric toothbrush was introduced in the 1960s.
Description
An Electric Toothbrush typically consists of a handle which holds the battery and motor, and a removable head with bristles that move in various patterns. The movement of the bristles can be oscillating (rotating back and forth) or sonic (vibrating at a high frequency). Some models also include features such as timers, pressure sensors, and different cleaning modes.
