There is a noticeable between the base of the brush head and the top of the toothbrush handle. I'm not able to get the brush head all the way on. Is there something wrong with the toothbrush?


A small gap is necessary because the brush head must be free to move in order to deliver the brushing action needed to clean the teeth. However, the brush head should not be loose, nor should it slip down the drive shaft during the course of usage. If this occurs, it can often be corrected simply by installing a new brush head on the handle. If the looseness persists after trying several brush heads, or the drive shaft is loose, contact Sonicare support to discuss your issue.
