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.

- Needle length: Long
- Placement site: Lingual gingiva halfway down the root of the tooth to be anesthetized.
