ORAL-B CrossAction Head Brush Black (EB50XF) 4 Pieces Brush head Black

This pack 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 use indicator: they change from green to yellow, so you can see when you need to replace the brush. Suitable for all Oral-B electric toothbrushes except Pulsonic and iO.
