Oralshark G 1 How often does the brush head of electric sonic toothbrush change?
The time for replacing the brush head of an electric toothbrush is actually the same as that of an ordinary toothbrush. Brush twice a day and change it every two months or so. Remember to change the toothbrush head on time. After the service life, the toothbrush head can not only brush teeth, but also breed a lot of bacteria, which is extremely unfavorable to oral health!
