A method and apparatus for effecting painless hypodermic needle administration of liquid anesthetics particularly in dentistry in which the needle is carried on a light wand and the anesthetic is delivered to the needle by motive means independently of the operator's fingers during penetration of the needle, with both the rates of penetration and expression of liquid being controlled to achieve intermediate numbing followed by a high rate of liquid expression, if desired, to achieve full anesthesia of the site.
