Abstract
A dental instrument for treating teeth with a laser beam has an output by a transmission element arranged in the head part of the instrument. The instrument is supplied with a gaseous agent which is conducted at least at the application side across the optics, particularly across the optical boundary surface of the transmission element facing toward the light exit side and will then flow out of the head part into the beam exit direction.
