Title: DENTAL TREATMENT APPLIANCE
Abstract:
A dental treatment appliance includes a handle, a nozzle for engaging the teeth of the user and for delivering a burst of working fluid to the teeth of a user, and a datum component also for engaging the teeth of the user. Each of the nozzle and the datum component is moveable relative to the handle. A control circuit detects relative movement between the nozzle and the datum component as the appliance is moved along the teeth of a user, and actuates the delivery of working fluid to the teeth of the user depending on the detected relative movement.
