The Crest Spinbrush eliminates the grunt work associated with brushing teeth by rapidly rotating its bristles with a battery-powered motor. All that you have to do is drag the spinning bristles over your teeth, and let the Spinbrush work its magic. Unfortunately, bristle heads eventually wear down and fail to clean as well as they once did. Have no fear, because removing your bristle head for replacement is a snap.
Turn off the Spinbrush and dry the bristles with a towel.
Grip the bristle head just below the bristles.
Twist the bristle head counter-clockwise 90 degrees.
Pull the bristle head away from the toothbrush grip.
