Oral-B Pro Sensitive Clean Electric Toothbrush Heads - Pack of 6

It is recommended to replace your brush head every three months, or sooner if the bristles become visibly frayed or worn, to ensure optimal cleaning performance and hygiene.

No, these brush heads are not compatible with the Oral-B iO series. They are designed for specific Oral-B handle types and do not fit the iO models.

While they are designed for sensitive users, it is best to use Oral-B's specifically designed kids' brush heads for children, as they may have different size and bristle requirements.

They feature extra-fine bristles that are softer and gentler on gums and enamel, providing a comfortable brushing experience for individuals with sensitivity.

These heads are compatible with most Oral-B electric toothbrush handles. If your handle is not part of the Pulsonic or iO series, it is likely compatible.

For hygiene reasons, it is strongly recommended that each individual uses their own brush head. Sharing can lead to the transfer of bacteria.

Ensure you are not trying to attach it to an incompatible Oral-B handle (Pulsonic or iO). Check for any debris in the connection port on the handle and on the brush head stem.

The brush head may need replacement. Replace it with a new one. Ensure the handle is fully charged, as a low battery can affect performance.

This might indicate excessive pressure during brushing. Try applying less pressure. If fraying continues rapidly, replace the brush head.
