    Maxillary Anesthesia Placement

    • Anterior Superior Alveolar Nerve

      • Anesthetizes: Central and lateral incisors, canine
      • Needle length: Short
      • Placement site: Height of the mucobuccal fold above the root of the tooth to be treated.
    • Middle Superior Alveolar Nerve

      • Anesthetizes: 1st and 2nd maxillary premolars, mesiobuccal root of 1st molar
      • Needle length: Short
      • Placement site: Height of the mucobuccal fold between 1st and 2nd premolars.
    • Posterior Superior Alveolar Nerve

      • Anesthetizes: Distobuccal & lingual roots of maxillary molars
      • Needle length: Short
      • Placement site: Height of the mucobuccal fold above the maxillary 2nd molar.
    • Infraorbital Nerve

      • Anesthetizes: Maxillary anteriors, premolars, and mesiobuccal root of the 1st molar
      • Needle length: Long
      • Placement site: Height of the mucobuccal fold of the 1st premolar.

    Palatal Anesthesia Placement

    • Nasopalatine Nerve

      • Anesthetizes: Palatal soft tissue covering central incisors
      • Needle length: Short
      • Placement site: On the palate posterior to maxillary incisors alongside the incisive papilla.
    • Greater Palatine Nerve

      • Anesthetizes: Palatal soft tissue from distal of cuspid to tuberosity
      • Needle length: Short
      • Placement site: On palate at the bisection of an imaginary line between midline to gingival margin of the maxillary 2nd molar.

    Mandibular Anesthesia Placement

    • Inferior Alveolar Nerve

      • Anesthetizes: Teeth and surrounding soft tissues in the quadrant
      • Needle length: Long
      • Placement site: Deep depression posterior to the retromolar area towards the lingual side of the ramus.
    • Incisive Nerve

      • Anesthetizes: Premolars to the midline, lower lip, and skin of chin
      • Needle length: Short
      • Placement site: Mucobuccal fold, facial to the apex of the tooth to be anesthetized.
    • Mental Nerve

      • Anesthetizes: Soft tissues from mental foramen to midline, skin of chin, and lower lip
      • Needle length: Long
      • Placement site: Mucobuccal fold between the mandibular premolars and cuspid.
    • Long Buccal Nerve

      • Anesthetizes: Buccal soft tissues on the facial side of mandibular molars
      • Needle length: Long
      • Placement site: Into the mucous membrane just distal and buccal to the last mandibular molar.
    • Lingual Nerve

      • Anesthetizes: Lingual soft tissue of mandibular teeth
      • Needle length: Long
      • Placement site: Lingual gingiva halfway down the root of the tooth to be anesthetized.
