Designed uniquely for the sonic toothbrush in the GO SMiLE Sonic Blue Teeth Whitening System. The oversized head allows for maximum light distribution through the mouth, for maximum efficacy.
To remove the brush head: grip the brush head tightly on the rubber sides, just above the neck of the toothbrush. Pull the brush head straight off of the brush, do not twist. The brush head fits snuggly to prevent it from accidentally coming off, so you will need to pull with some force.
To replace the brush head: Align the brush head so the bristles face the same direction as the buttons on the handle. Firmly press the brush head down onto the shaft until it stops and is snugly in place. Replace your Sonic Blue toothbrush brush heads every 3 months to achieve optimal results.
