Oral-B CrossAction Toothbrush Head Black Edition with CleanMaximiser Technology - 8 Pack

You should replace your brush head when the CleanMaximiser bristles change from green to yellow, or approximately every three months, whichever comes first. This ensures optimal cleaning effectiveness.

No, these Oral-B CrossAction brush heads are NOT compatible with Oral-B iO series toothbrushes. They are designed for all other Oral-B electric rechargeable toothbrushes, except Pulsonic models.

CleanMaximiser Technology is a feature where the green bristles on your brush head gradually fade to yellow over time. This color change indicates when it's time to replace your brush head to maintain 100% cleaning efficacy.

The perfectly angled bristles are designed to reach deep between teeth and along the gumline, effectively removing up to 100% more bacterial plaque than a manual toothbrush for a superior clean and healthier gums.

The 'Black Edition' refers to the color of the brush head, which is designed to aesthetically complement black Oral-B electric toothbrush handles, offering a cohesive look for your oral care device.

No, these brush heads are specifically designed for use with Oral-B electric rechargeable toothbrush handles and cannot be used with a manual toothbrush.

The X-shape bristles are a design innovation that allows the brush head to clean more effectively in areas that traditional round bristles might not easily reach, enhancing overall plaque removal.

Verify your Oral-B toothbrush model. These CrossAction heads are not compatible with Pulsonic or iO series toothbrushes. Ensure you are not trying to force it onto an incompatible model. If it's a compatible model, ensure the head is aligned correctly with the shaft and pushed firmly into place.

The color change from green to yellow is a gradual process that occurs with regular use over approximately three months. If you've been using the head consistently for this duration and see no change, ensure the bristles are not excessively splayed or worn in other ways. If the head is still relatively new, continue using it normally. If it's old and still hasn't changed, replace it based on the recommended three-month guideline anyway.

Check the bristles on your brush head. If they are splayed, frayed, or have significantly faded to yellow (due to CleanMaximiser Technology), it indicates the head needs replacement. Worn bristles lose their effectiveness in removing plaque. Replace the head with a new one to restore optimal cleaning performance.

Ensure the brush head is fully pushed down and clicked into place on the metal shaft of your toothbrush handle. If it's correctly attached and still feels loose, inspect the shaft and the brush head for any damage. If damage is present, replace the affected component.
