If the brush base accidentally touches the teeth, once, twice or three times is ok. If the number of times is too much, it is always bad, and the total vibration of high frequency and low amplitude will have accumulation effect on tooth damage. If a friend's teeth already have a certain degree of crack, the brush head seat of the electric toothbrush should be touched 1~2 times every time when brushing.

The movement and speed of electric toothbrush are not familiar, should they be the same as manual ones? I feel like I can't brush the inside of my teeth. There are many differences between the use of electric toothbrush and manual toothbrush. Electric toothbrush gently put a little pressure on the teeth, through the electric toothbrush's own high-frequency, low-amplitude vibration, can play the effect of cleaning teeth. After brushing two or three teeth, you just need to move the brush head to the next tooth and press it down, and then let the electric toothbrush clean automatically. Repeat this process until all the teeth have been cleaned. Therefore, when using electric toothbrush, the wrist does not need to keep swinging like manual toothbrush. The role of electric motor is to replace the swing of the wrist and liberate the wrist. Do not, the electric toothbrush is vibrating at the same time, the wrist also keeps swinging like using manual toothbrush, which loses the meaning of using electric toothbrush. According to the reason, the cleaning of the inner toothbrush is similar to manual toothbrush. The head of the electric toothbrush can be pointed at the inner teeth, and it will automatically vibrate to clean the teeth. At this point, it also needs to be clear that the cleaning techniques of different electric toothbrushes are not the same. Let's talk about them in detail.
