Oral-B CrossAction X-Filament Bộ 2 cây

I was skeptical about spending extra on brush heads, but the cross-action bristle pattern really does reach the back molars way better than my old flat ones. My dentist even commented on how much cleaner my gum line looked at my last checkup.

The angled bristles on the head get into the back molars way better than any flat brush I’ve used, and the softer outer filaments feel surprisingly gentle on my gums. I just popped the second one in the travel case for weekend trips.

My dentist actually recommended these, and the cross-action bristles really do a better job grabbing plaque along the gumline than my old brush heads. The duo pack is a solid deal, and I can already feel the difference after a week.
