A light irradiating means capable of specifically extracting the affected part of a tooth is provided to a treating instrument such as a hand-piece provided with a dental treating tool or the like to facilitate the treatment of the affected part. A light emitting light source able to specifically extract an affected part is provided in the vicinity of a hand-piece-head for permitting the mounting of a treating tool thereto. Light emitted from the light source irradiates a portion in front of the treating tool. Or, a light source includes a plurality of light emitting elements and is disposed at the peripheral edge of the tip end of the hand-piece-head so as to surround the treating tool to thereby irradiate a portion in front of the treating tool. When the interior of an oral cavity is irradiated with the light, the treating operator can observe it by using a filter function for its fluorescent reflection light to thereby able to confirm the affected part while treating it.
