Oral-B CrossAction X-Filament 替換刷頭，3入裝

The angled criss-cross filaments feel noticeably sturdier than my old flat-bristle heads, and they've held their shape for over two weeks of twice-daily brushing. My dentist even commented on how clean my back molars looked at my last checkup.

The criss-cross bristles really get between my back molars—my hygienist even commented on how much cleaner things looked at my last visit. Each head feels firm but not harsh, and the three-pack lasts me a solid few months.

I’ve been using these for about a month now and the X-shaped filaments really do feel like they’re digging into the tight spots between my molars way better than my old brush. They hold their shape pretty well, too, not splaying out after a couple weeks like I’m used to.
