Abstract
An electric toothbrush is disclosed comprising a body, a head, and a neck extending therebetween. A motor, drive train, and one or more batteries impart motion to the collection of movable bristles. A spring component is provided in the drive train that is configured to absorb excessive loads that would otherwise be transmitted to the motor. Reducing or eliminating application of such excessive loads on the motor extends battery life.
