The loud sound and continuous vibration of an electric toothbrush is driven by a unique technology that helps remove plaque from your teeth. Learn about the full technology behind this sound.
Electric Toothbrush Technology
The use of electric toothbrushes is rapidly increasing today. People are now replacing regular toothbrushes with brushes equipped with features like motors, vibrations, timers, and pressure sensors. However, many find the loud noise and constant vibrations of electric toothbrushes a bit odd. This technology helps remove plaque from teeth. So, let's understand why electric toothbrushes make such a loud noise.
Why does an electric toothbrush make a loud noise?
Electric toothbrushes have a small motor embedded in their handle. This motor rapidly rotates or vibrates the brush head. The technology may vary between models. Some electric toothbrushes simply rotate the head back and forth, while others rapidly vibrate. This rapid movement of the brush head produces the sound you hear during use. Its primary purpose is to remove plaque from the surface of your teeth. Plaque is a sticky layer of bacteria that can cause problems with your teeth and gums.
The features of an electric toothbrush are also special.
Electric toothbrushes also come with features like a timer and a pressure sensor. The timer helps ensure you brush for about two minutes, while the pressure sensor can alert you if you're applying too much force. Applying too much pressure is not the right way to brush and can damage your gums and teeth.
Does an electric toothbrush clean better?
A Cochrane Systematic Review of electric toothbrushes included data from 56 studies and 5,068 people. The study found that compared to a standard toothbrush, powered toothbrush users experienced a slightly greater reduction in plaque and gum inflammation. However, the long-term benefits are unclear. Both standard and powered toothbrushes are effective when used correctly.
For whom is an electric toothbrush more useful?
Electric toothbrushes can be convenient for people who struggle to brush properly by hand. They can also be useful for the elderly, those with limited hand movement, and those wearing dental devices like braces. If brushing requires too much pressure or frequently misses certain areas of the teeth, an electric toothbrush with a timer and pressure sensor may be helpful.
