Oral-B CrossAction Toothbrush Head Black Edition - 4 Pack

It is recommended to replace your brush head every three months, or sooner if the bristles appear worn or splayed. The bristles' color indicator (green to yellow) will also help you determine when it's time for a replacement.

These CrossAction heads are compatible with almost all Oral-B electric rechargeable toothbrushes, except for the Oral-B Pulsonic and Oral-B iO series models. Please check your specific toothbrush model for compatibility.

The unique X-shape bristles are designed to reach and clean areas that traditional round bristles might miss, providing a more comprehensive clean, especially in interdental spaces and along the gumline.

Oral-B CrossAction brush heads typically come in one standard size, optimized for effective cleaning across most adult mouths. Smaller brush heads are often available in specific ranges for sensitive teeth or children, but the CrossAction model is standard.

The bristles on your CrossAction brush head feature a built-in usage indicator. The green bristles will fade to yellow approximately halfway down as they wear. Once they reach this point, it's time to replace the head for optimal cleaning performance.

While the CrossAction heads provide a deep clean, their angled bristles are primarily focused on aggressive plaque removal. If you experience sensitivity, Oral-B offers other brush head types, such as 'Sensitive Clean', which might be more suitable.

Check if your toothbrush is an Oral-B Pulsonic or iO series, as these heads are not compatible. Ensure you are aligning the head correctly onto the metal pin and pushing firmly until it clicks into place.

Ensure you are not applying excessive pressure while brushing. Electric toothbrushes are designed to do the work for you; a light touch is sufficient. Replace the head if bristles are splayed, as this reduces effectiveness.

Confirm the brush head is securely attached. If the usage indicator shows bristles are yellow, replace the head immediately. Brush for the recommended two minutes, ensuring you cover all tooth surfaces and the gumline.
