YY-Dental Pro Replacement Brush Heads 4pk
To remove the OLD brush head, grip the brush head tightly on the rubber sides, just above the neck of the toothbrush with one hand. Pull the brush head straight off of the brush with the other hand, then wiggle back and forth to loosen – don’t twist. The brush head fits snugly to prevent it from coming off, so you’ll need to pull with a little bit of force to remove it. To replace the NEW 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 toothbrush handle until it stops firmly in place.
