Oral-B Precision Clean X-Filament 刷頭，6入

The X-filament bristles really dig into the gumline, and the angled tufts reach spots my old brush heads missed. I’ve noticed less plaque buildup between dental visits, and the six-pack lasts me about four months with twice-daily brushing.

The indicator bristles fading is a nice reminder, but honestly the X-filaments themselves feel way sturdier than the standard ones I used before. I can feel them grabbing more surface area along my gumline, and my last checkup showed noticeably less plaque buildup.

The blue indicator bristles fade right when it's time to swap, which is so handy. The X-shaped filaments really do seem to catch more between my molars than my old heads ever did.
