First, traditional toothbrushes are manual, and it is difficult to completely remove plaque. As far as Xiaobian's personal experience is concerned, Xiaobian usually feels tired after brushing and brushing, so the hand will feel sore, so the three-minute brushing time is compressed to one minute, which is obviously not conducive to cleaning the teeth.

　　Experiments have shown that electric toothbrushes remove 38% more plaque than manual toothbrushes, and oral experts at home and abroad have given unanimous praise.

　　Secondly, improper brushing can hurt our gums. The slight vibration caused by the high-speed rotation of the electric toothbrush can not only promote blood circulation in the oral cavity, but also have an unexpected massage effect on the gum tissue. As for whether it is like itching, you can test it yourself ~

　　In addition, when we use ordinary toothbrushes to brush our teeth, we sometimes inevitably brush too hard, or we can brush up and down, left and right, these improper behaviors will cause damage to teeth and gums. Experiments show that electric toothbrushes can control the strength very well, reduce the brushing strength by about 60%, reduce the frequency of gingivitis and gum bleeding by 62%, and make the brushing process safer and more effective.

　　If you are looking for whitening and beauty, electric toothbrush is a better choice.

　　Electric toothbrush can effectively reduce tooth stains caused by tea, coffee and bad oral conditions, remove dirt and restore the original. However, the electric toothbrush is not immediate, and it is necessary to insist on long-term use to ensure the desired effect.
