Oral-B iO 終極清潔替換刷頭，1入，白色

The micro-vibrations from these heads feel noticeably gentler than the standard ones I used before, yet my teeth have that just-left-the-dentist smoothness after brushing. The round design reaches my molars way better than any rectangular brush ever did.

I’ve had these brush heads on my iO for three weeks now, and my dentist actually commented on how much cleaner my gum line looks at my last checkup. The round head reaches those back molars way better than any rectangular brush I’ve used before.

The micro-vibrations feel way gentler than my old electric brush, but my teeth still come out with that just-left-the-dentist smoothness every single time.
