The personal experience of a friend who is very prone to gum bleeding tells me that there will be 4 or 5 gum bleeding after brushing your teeth 10, and it will be reduced to 1 0 after using an electric toothbrush.

Secondly, the first time I bought an electric toothbrush, I bought dozens of pieces sold in the supermarket, and I bled every time I used them. Later, after replacing it with a sonic toothbrush (which was also used by the friend above), the gums would not bleed, and it was much cleaner than a manual toothbrush. In particular, the timing function allows you to brush for 2 minutes at a time.

Thirdly, as I said above, you can't buy dozens or even hundreds of electric toothbrushes in supermarkets, which is why many people complain that electric toothbrushes will be covered in blood. You might as well buy an electric toothbrush with sound waves.

Although the landlord is talking about an emerging brand, it is still worth starting to understand the cost performance.
