Oral-B CrossAction X-Filaments Replacement Brush Heads Refill, Black 3 Count

These heads lock onto my handle with a solid click and the X-shaped bristles really dig into the gaps between my molars. My hygienist actually commented on how much cleaner my gumline looked at my last checkup.

The fit on my brush handle is snug, no wobble like some off-brands I've tried. The X-shaped bristles feel noticeably stiffer and get into the back molars without me having to press hard, and the black color hides toothpaste stains well between changes.

The X-shaped bristles really do a better job of grabbing plaque in the back molars—my hygienist even commented on the cleaner pockets at my last visit. Three heads in the pack means I’m set for months, and the black color hides toothpaste stains way better than my old white ones.
