No matter how to brush electric toothbrushes, the method is the most important, and insist

The American College of Stomatology recommends brushing our teeth twice a day, morning and evening, and the vast majority of us do the same.

However, the modified brushing method recommended by the dentist is a little more complicated for the average person.

This technique requires "45°", "brush lightly press teeth", "cover a bit of gum", "horizontal short distance movement" and so on. According to the research, after learning this method, only no more than 30% of the adults can adhere to more than a week, can persist for a long time is very rare. What's more, manual brushing is often arbitrary, with some people brushing too quickly. Dentists usually expect people to brush for two minutes, which is about 30 percent more effective than brushing for one minute.

Unfortunately, for most people, even when you stress the importance of brushing their teeth, they still only brush for a little over a minute.

While a regular toothbrush may work best if you brush your teeth "correctly," there are too many lazy people in the world, and chances are you're one of them.

Electric toothbrushes, not just "Manual Toothbrush Enhancements"

There are two basic types of mainstream electric toothbrushes on sale at present. One is rotary vibration, also known as left-right rotation; The other is the sonic form.

Rotational vibration is actually the high speed of the brush head clockwise, counterclockwise rotation repeatedly, some models also joined the high frequency of the whole brush head back and forth oscillation. Instead of using sound waves to clean them, the sonic type gets its name from the fact that its frequency (more than 260 times per second) is within the range of the human ear.

In fact, from the working principle, the working mode of the electric toothbrush, is a manual toothbrush in any case can not reach. Rotating vibratory like an automatic car wash, equivalent to a quick scrub around the teeth in all directions; Sonic toothbrushes, while similar to manual use, but the scrubbing amplitude and frequency is much greater than manual.

Standard use, electric toothbrush better effect

Regardless of the principle, we judge which toothbrush is good mainly by its practical effect.

The most important thing about brushing is to remove plaque. Plaque can erode the surface of teeth, leading to cavities, and long-term attachment to teeth can lead to problems such as gingivitis. From these two aspects, rotary vibratory toothbrushes have obvious advantages. In the past 20 years, 27 relevant studies have found that after three months of use, rotary vibratory toothbrushes have 21% less dental plaque and 11% less gingivitis than manual toothbrushes.

The concern that electric toothbrushes harm teeth and gums has also been proved unnecessary by studies: regular use of electric toothbrushes does no harm to teeth and soft tissues, and is less harmful to gums than manual brushing.
