Abstract
A method of attaching a brush head to an oral cleansing device is provided. The method may include inserting a drive shaft of the oral cleansing device into a shaft of the brush head. The method may include causing, in response to inserting the drive shaft into the shaft of the brush head, a cantilevered beam inside the shaft to bend outward, creating a reactionary force that presses against the drive shaft.
