ORAL B Pro Cross Action brush heads Pack of 4 Brush head Black

This package contains 4 black Oral-B Cross Action brush heads with X-shaped bristles, which clean where round bristles cannot reach. More than 2,200 bristles are angled at 16 degrees to remove up to 100% more bacterial plaque than a manual toothbrush. They effectively clean along the gum line and deep between teeth. The bristles have a usage indicator: they change from green to yellow, so you know when to replace the brush head. Suitable for all Oral-B electric toothbrushes, except Pulsonic and iO.
