Cross Action replacement heads for Oral-B electric toothbrushes. The rounded shape is designed for tooth-by-tooth cleaning. The filaments are arranged at a 16-degree angle to help clean effectively along the gumline. This angle helps to penetrate deeper between teeth to break down and remove up to 100% more plaque for a deep clean.
The filaments become discoloured to indicate that the brush head needs to be replaced.
