Electric toothbrushes make brushing easier, but how do they actually work? How do they clean your teeth? Aiwejay Electric Toothbrush Manufacturers Here's the answer.
Electric toothbrushes have two basic cleaning mechanisms:
1. Rotation
In the early basic models of electric toothbrushes, the cleaning mechanism consisted of a small, rotating head that spun to clean the teeth. This was followed by the introduction of the “rotating-oscillating” brush head, which rotates in one direction and then in the other.
According to reports, these types of toothbrushes (rotating-oscillating) are more effective than manual toothbrushes at reducing plaque and gingivitis. The pulsating motion—known as oscillation—means that as the rotating-oscillating brush moves, the brush head pulsates back and forth. This stimulates the mouth to remove plaque from areas that the bristles cannot reach. A rotating brush head features a small, round tip that works on only one tooth at a time.
2. Vibration (Sound Waves and Ultrasound)
Electric toothbrushes with vibrating heads vibrate at a very high frequency to break up plaque. The brush head moves at a very high speed so that the bristles rub against the teeth. This high-speed vibration creates powerful pulses that agitate oral fluids and produce a non-contact cleaning effect (as is the case with rotating-pulsating toothbrushes). The brush heads in oscillating-vibrating toothbrushes are similar to those on manual toothbrushes; unlike in rotary toothbrushes, they are not circular.
Due to their extremely high vibration frequencies, sonic and ultrasonic toothbrushes have a very high number of brush strokes per minute, which is undoubtedly the most important and distinctive feature of these modern electric toothbrushes.
