In some individuals, the mylohyoid nerve provides accessory innervation to the first molar, usually the mesial portion of the tooth. In this situation, there are two options to obtain anesthesia to the first molar:

administer a PDL injection to the first molar

using a 25-gauge needle, administer local anesthesia to the apical region of the tooth just posterior to the tooth in question, in this case to the apex of the second molar
