 The brush of electric toothbrush is rotated, so it needs to stay on each tooth for a period of time, taking into account three teeth, in order to achieve the purpose of cleaning teeth, which is time-consuming. Therefore, the use of electric toothbrushes requires sufficient patience in order to truly clean teeth. If you just put the toothbrush in your mouth and move up and down synchronously, you can’t completely clean the pits and fissures of teeth, gums and crevices, and other special parts of the bacteria, it will also cause dental disease. Correct use of electric toothbrushes does have the effect of removing plaque, preventing dental caries and periodontitis, but these functions are the same as ordinary toothbrushes. Electric toothbrushes only change the way people brush their teeth, and can not completely replace the role of cleaning teeth. However, when many people brush their teeth manually, due to improper ways and excessive brushing force, it is easy to cause unnecessary damage to teeth and gums. Electric toothbrush can reduce this damage and massage the gums.
