The invention provides a unitary cordless dental drive apparatus with a cantilever arm extending outward and positioned to allow a dental nose cone to be connected. An activating switch is located at the free end of the cantilever arm in a position that is convenient for manipulation by a user. In a second embodiment, the switch is in the form of a contactor mounted below the cantilever arm to contact the nose cone when pressed. In a third embodiment, a foot pedal connected to a wireless transmitter is provided to send a signal to a receiver located within the handpiece for activating the handpiece.

A dental instrument system has an optical component with a mirror for the dental practitioner to view a patient's mouth. A light source and an airflow source have a plurality of output levels that are controlled by a user input on the handle, such as a single button. The output levels of the light and airflow are controlled by a single or double click, wherein a single click increases the output level of the airflow and a double click increases the output level of the light, for example. The light source illuminates the mirror and the airflow source produces airflow over the mirror to remove debris and bodily fluid. A clearing flow of air may be initiated by holding the single button down on the handle and release of the button may return the airflow to the previous level.

Dental hand piece, comprising a housing and a drive train with a coupling element for a drive, wherein the housing radially surrounds the drive train and wherein the housing has a first and a second housing end, and wherein the housing is held on the drive train on the first and on the second housing end. Between the first housing end and the coupling element is arranged a decoupling element, which is strictly springy or springy and damping in the axial direction, whereas the second housing end is braced rigidly against the drive train and the housing is braced with respect to the coupling element in the axial direction by means of the decoupling element.
