Abstract
An electric, motorized toothbrush includes a switch that has an 'automatic' position. The 'automatic' mode provides for intermittent motorized operation, which is dependent upon application of an external force. Various embodiments allow for the force to be exerted either on the toothbrush handle, such as when it is gripped by the user, or on the brush head itself--e.g., when the brush head contacts the user's teeth. A substantially hollow housing allows for placement of battery, motor, gears, and linkages to facilitate motorized movement of the brush head.
