The efficiency is much higher than that of the manual toothbrush, but it also has higher requirements on the bristles. Damage to the gums during brushing

Electric toothbrushes are divided into many types according to the improvement of technology. Generally, the teeth are cleaned by vibration rotation, and some high-grade ultrasonic instruments are used to clean teeth by pulse and water spray.

Therefore, the use of an electric toothbrush requires sufficient patience to really clean the teeth. If you just put the toothbrush into your mouth and move it up and down without synchronization, you can't completely clean the bacteria in the special parts such as the pits, gingival sulcus and interdental joints of the teeth, which can also cause dental disease. Proper use of electric toothbrush does have the effect of removing plaque, preventing caries and periodontitis, but these effects are no different from ordinary toothbrushes. Electric toothbrushes only change the way people brush their teeth, and they can't completely replace the role of cleaning teeth.

However, if the electric toothbrush is used in the wrong way, it will cause damage to the teeth. Usually, ordinary toothbrushes are actively brushed up and down, that is, vertical brushes. The vibration frequency and strength of the electric toothbrush are relatively fixed. When rotating, the surface of the tooth is similar to the horizontal brush, which may cause certain wear on the teeth, which may cause periodontitis. If the teeth themselves are not very good, such as gingivitis and periodontitis, it is best not to choose an electric toothbrush.
