The injection site for mandibular injections is one-half tooth distal to the target.If one wants to anesthetize the mandibular first molar,the injection site would be between the mandibular first and second molar (one-half tooth further distal to the target site).This is because the anesthetic solution needs to penetrate bone and arrive at the inferior alveolar nerve in a location posterior to the target area.
