ABSTRACT:
A pressure dental anesthesia device comprising a needle guiding element attached to a handle and having a tip suitable for pressing against a living tissue area to be anesthetized. The needle guiding element has an elongated cavity which narrows at the pressure tip to localize the needle and widens towards the distal end of the cavity so as to facilitate the positioning and guidance of the hypodermic needle in the cavity at a safe distance from the tissue.
