Why do I need to change a power toothbrush brushhead every 3 to 4 months?
• Like manual toothbrushes, the bristles on power toothbrush brushheads also wear with use. To ensure consistent, effective plaque removal, the brushhead should be replaced 3 to 4 times a year, depending on the brushing technique of the user (people who use more brushing pressure wear out the brushhead faster) and frequency of use. To let you know when it is time to switch, all Braun Oral-B brushheads (except the Ortho) have Indicator bristles. These colored bristles provide an excellent means for monitoring bristle wear and brushing pressure. When the color fades halfway, usually after 3 to 4 months, the brushhead should be replaced.
